OK, here is my 2 cents.., first, get your ph to 5.8.second, stop with the nutrients..this is still seedlings, no nutes needed. third, get temps right, maybe too hot in there, put fan on across top, but NOT affecting plant yet...just to keep cool.stop with the nutes, just keep rockwool wet with 5.8 water, that's all.nutes at seedling stage with your ph will kill this plant.
Hi there! I don't work with hydroponics but is suppose deficiency signs are the same as in soil. If this started from older leafs and kind of creeped up it's a mobile deficiency, I would say Mg first and Potassium second, not sure. Calmag product could help I think. But if it's something that showed up even on younger leafs then it is a imobile deficiency then I would think of a Zinc deficiency. Good luck bro!
Hahahahaaa you killed me bro with your electric bill 😄😄😄
After looking, you have thrown a lot of light on the floor, not enough plants and too much light, you could have saved the half bro
As @Thizzle suggested they will be monsters. Plants look great. Thumbs down 👎 on your photo uploading skills. I admit I’m a picture Nazi. Out of focus, blurple pics are the worst offenders, and at least you didn’t do that. But well shot pics uploaded sideways are an even more frustrating crime! Lol.
You’ll do well. Enjoy your harvest.
