 So to the blind eye, these tomatoes that I have growing inside my grow tent here seem pretty healthy. They are producing fruit. Tomatoes are growing, but I noticed we have some blossom and rot. All these ones that I have pulled off the tomato plants are turning brown. It seems like as soon as they get to a certain size, they're turning brown. So we're going to try refreshing the nutrients, adjusting the pH and the EC on each of these. Give them a fresh start and see if we can stop this blossom and rot and get some a good harvest of tomatoes. So I use these inverted tomato cages on my tomatoes here, which works out really good for giving them stability, but it's going to make it a little tricky now to treat this plant and change out the water because I don't really want to have to remove this cage. So we'll see how that goes. I'm going to remove some of these lower branches that are kind of dying off. I'll just run a test on the water here and show you what levels they are right now to see where they're at, show you where they should be, and then we'll go from there. First I'm going to test the EC level and see what it's at. So it's giving me a reading of 3853, which is 3.8. According to my little chart here that I followed, the tomato should be 2 to 4, so it's really not that bad as far as the TDS level. So the pH is coming out at 6.63, which according to my chart is not overly high. It's a little bit over the range that it should be, but still not super high that it should be causing a problem with the Lawson and Brott. The other thing that could be happening is a calcium deficiency in the water, which is something that can be adjusted using some CalMAG. So I'm just going to mix up a new batch of nutrients with some CalMAG added to it and refresh these containers for my tomatoes. See what happens. Start by removing the plant with the cage and temporarily relocate into this pail. The roots don't look super healthy. I might give them a bit of a treatment with some peroxide in water as well, and I'm just going to dump out this nutrient water and mix up the fresh batch. So while I mix up my nutrients, I have put some water into this pail, added two capfuls of hydrogen peroxide, and just giving those roots a little soak in there. So I'm going to mix up a four liter batch of nutrient water here with my two-part root farm. It's easy that way because this is the measurements on the back here are based on a four liter container, so I always use this as my starter. Once we get it into the container for the plant, it may be that we have to water it down depending on how the EC levels come out. First of all, I'm just going to mix it all up in here, and hopefully this is enough to fill my three containers that I'm replenishing. So we're at the mature growth stage for these tomatoes. So I'll be using the measurements provided here for mature growth stage. So part one is 15 mils. Part two is 10 mils. And these caps work out to be five mils apiece, so that makes it easy for measuring. And the measurement for the kelm ag is one teaspoon per gallon. So four liters here is the same as a gallon, so we'll be adding one teaspoon to this mixture. Okay, so now we're ready to set up our container for the tomato to go back into. And as per my chart here for the tomatoes, the EC level we want it to fall in between is the 2.0 to 4.0. So I'm going to pour this in, take a measurement and see if we need to add water or what the EC level turns out to be. So I have about three inches of nutrient water in there. Let's see what the EC level comes out to. So it's coming out pretty high, 6.948, which is 6.9. Okay, so I just kept adding a little bit of water at a time and measuring and adding a little bit more water, measuring, and I now have it down below that 4.0 at 3.7. So I'm going to stick with that right now. So now that we've got the ECs kind of at a level that we want them to be, we're going to check the pH. So again, I look at my card for tomatoes. We want to have that pH level somewhere in the 6.0 to the 6.5 range. So let's see where it's at right now. So usually with the pH meter, you are supposed to leave it in there for about 30 seconds to make sure you get an accurate reading. So it seems to be sitting at 6.53. So that's pretty much on par. I'm not going to mess with it tonight. Like I said, I like to just get it close and check it daily over the next week and just see see how it goes. So this tomato is ready to go back in here. I put it back into the grow tent and I'll bring out the other two and do the same thing with them. So I'm just working on my third tomato plant here and it has definitely got some blossom and brot issues. I'll just show you the tomato. I'm going to remove all the tomatoes off this plant that are showing signs of blossom and brot because they're not going to get any better now. So I'll take them off, feed them to my compost bin, to my worms, I guess. So this one came out with a little bit of a high pH in it. So I'm just going to show you how I'm going to bring that pH down. It's not too high. It should be for the tomato somewhere to the 6.0 to 6.5 range and it's reading right around 7. So it's not super high, but I thought I'll just try a couple drops of the, whoops, not that one. Make sure you use the right one, pH down. We want to bring it down slightly. It seems like with my water that the pH is normally higher than lower. So I'm just going to add, and it doesn't take much, three drops. We'll see how that affects it because we don't need to go down too much. A couple more drops. Just about at that 6.5. So it's pretty close. Maybe a couple more drops. It's pretty much right on 6.5. So that's good enough for today. So hopefully soaking these roots in this water with some peroxide is going to give the roots a nice little cleaning and treatment. I trimmed off some of the lower branches that were kind of dead and lifeless. I've taken off all the tomatoes, like I said, that have the blossom and rot and we'll put it back in the tent and see if all these things we've done to it tonight are going to help these tomatoes. Okay, so all three tomatoes have had their nutrients refreshed. I've adjusted the EC levels and the pH levels on them. The nutrients contain a little extra kelm ag. So I'm not sure what else to do to try and save these tomatoes and improve the quality of them and get rid of that blossom and rot. So I will keep you updated. Check on these every few days. I'll continue to check the levels in the water to see if they stay the same. If anybody has any other suggestions, I would love to hear them in the comments. So it has been a couple weeks since we have done the treatment on these tomatoes where we refresh the nutrients and added a little extra calcium and I'm going to just take out one of these plants now. We're going to have a look at it up close and see how it's doing. So it has been a couple weeks since I have refreshed the nutrients on this plant and since then I have been checking the EC levels and the pH, keeping it adjusted, adding a little more nutrients, adding water depending on what it's been doing. And I've noticed that since that I have been maintaining that process with this plant that it really has been absorbing a lot more water. So I'm checking it every few days and finding that it's drinking drinking it quite a bit faster than it was. So I think that is a good sign that, you know, the pH level is at a good level that the plant is able to absorb the nutrients. And so we're just going to have a quick look here at whether we've solved the blossom and rock problem. And I've noticed on these little ones here that I still have that issue with them. And then over here we have another batch of tomatoes coming. So I've been checking the bottom and I see I still have a bit of a problem there. But these other ones, not so bad. So I'm hoping that, you know, this is helping out a little bit. I'm also been mixed up some cow mag and water here and give it a little shot of that just to give it a little extra calcium. So this is my other tomato plant I just brought out and I believe I had removed pretty much all the fruit that was on it that was showing the blossom and rot. And we've got a whole batch of new tomatoes coming here, and I don't know if you can see this, but so far no signs of blossom and rot on the bottom of these. And there's another small batch coming here so far so good. So I'm hoping that this treatment process that I'm following now with my nutrient water is working and we're going to keep getting some tomatoes that are going to hopefully grow a little bit more and ripen. I just wanted to give you a close-up here too of the roots. I think that they have really improved also since giving them a soak in that peroxide water. There's lots of healthy air roots coming here. They look fairly nice and white and healthy, so that's good. So before we put this tomato back into the grow tent, I'm just going to test out the EC levels again in the pH. So right now the EC level is showing at 3.45. So according to my EC chart here that I usually follow, we're still within that two to four range, so that's okay. I might just top it up just because the level is getting pretty low here with a little more nutrients, a little more water. Get it balanced before we put it back. Like I said, I've been finding these tomatoes are really drinking up the water a lot quicker now, so you really have to keep an eye on it every day because I found that just some days all of a sudden it is dry, which causes a little stress on the tomatoes. So we'll test this again. So still below four. Just give it a little splash of water. And then we'll just check the pH here. So the pH is registering at 6.6. Here's my range that I like to keep it in. So I'll give it a little shot of the pH down just to bring it down just a little bit. Again, only one or two drops is needed. So it's sitting at 6.47, so that's good. So this tomato plant is ready to go back into this grow tent and hopefully in the next couple weeks we'll see some ripening happening. So if you are having issues with growing tomatoes indoors, I hope that you found this video helpful. And if you haven't started growing food indoors hydroponically, I hope that you will give it a try. I have a whole bunch of videos on my channel that you can check out and learn how to grow food indoors using the Kratky hydroponic method. Thank you for watching.
