Hydro for Dummies (me) ;D

@BeefWellingtons,How are you man? I put some new photos, because today I noticed the problem at the other plant. any idea?

@BeefWellingtons,Surely it will have happened to me at the beginning of having sprayed water on the leaves. I use a heated greenhouse, but the temperatures in my country mean that there is no need to turn it on (when I turn it on, the temperature rises to 30 degrees celsius). this morning I turned the cubes as you suggested, so as to give the right light from all sides. As for water, I bought a reverse osmosis system (the water in these parts is really disgusting), so as to bring the levels of ec at the minimum. I will only have to try to bring the right amount of calcium and magnesium to the plant, which apparently in hydroponic fertilizers is slightly lower than soil. Today I will change at 18/6 hours of light / dark so as not to stress the plants too much. thank you for your time. 🙏

@Sora85, well I asked the same thing a long time ago. My suggestion would be to ph that water to 5.8 exactly. Keep it wet, but not soaked. I let mine dry out by accident and they fell over and then stunted (really bad). I would have said yes to the move, however you put them in those huge squares. When you move them, they should have a substantial root system growing out of the bottom. Not just the tap root but a few roots. Because you put in larger squares, you need to wait it out, no worries though, you should see something pop out soon enough. Is that seedling nursery on a heat pad? If yes, dial down the heat by 2 degrees or so. My 2nd grow plant had the little leaves that turned yellow and fell off. This is just a warning that something is not perfect for the plant. Since you look like you have the right temps, keeping medium moist, then it's either the light/heat, or wrong ph water. Since you have a cover over them, I don't think its light, also they are leggy/tall (like mine were), so last thing would be ph water...research it, hydro loves 5.8 (there is nutrient lockout above and below this number). Once you are flowering you can kinda drift between 5.8-6.0. Also, are you using tap water? I do. I will keep an eye on your grow and help ya out when I can. Good luck!!

@BeefWellingtons, I'm following the guidelines dictated directly by the manufacturer, even as the starting ec was much higher. the main doubt was whether to move the seedlings in the hydroponic system or wait. Doubt then clarified by the expert and also by you. Did you see those yellow specks and those folded leaves? What do you think about it? Thanks for your advice 😉

@bobo420, Thanks 👍

@BeefWellingtons, Thanks Man! 👍
