Yellow leaves

Hi. Theres good views here. Theres a ditate that says, if you care too much it will dies. But cannabis like water plenty and the right temperature. I live tropical area so, i just choose plants accostume to sun heat. The second view i would say, calcium deficiency is a b^*^ . I add 1% milk. Sometimes 1% magnesium milk phillips if nedded. Need make compost with eggs shells, helps a lot. Sea shells is a big enviroment damage. Cant get toomuch from beaches... but need a calcium with good absorbtion. So i hope the plants recover well , vegetation phase is althe only good phase for mistakes. Try to water with oxygenated air bubbles. Nitrogen too, it will make strong plants. When learn about phisiologies, the proteins uses monomers singles blocks. To make canabinoids it need sulphurs proteins, like cisteíns. So try to add a Sulphur suplement too, some metals acts like enzymes. I will try to oxydate some iron nails for sulphurs ferrous oxytes. Sorry bad english.

Nitrogen deficiency and heat stress. I'd bury or transplant that pot into the earth, do not let it sit in the sun, its heating up the root mass to much. Its also getting to small for how big they will get. Good Luck!

I gave my plants about 2/3 times the Plagron grow and roots nutrients. In the beginning I gave them a too strong solution and they didn’t like that. So I got really careful with giving them it. I don’t know the pH, I’ll look if I have some pH sticks somewhere

Hello. My first guess could be under or overwatering. But first, how much are you giving in terms of nutrients? And what PH you using? (You could use the liquid PH test kit, cheap and always worked with me)
