My Royal Creamatic has the edges of their leaves pointed down, loosing soil and some yellowing in the older leaves. I've tried to use google but there were many opinions about this. Have the feeling that I should just give ph water for now. Any ideias/advice? Thanks

I may have over watered or it could be nutrient lockout. I only feed them every 10days to 2wks. I was switching them over from 1 fert to bloom fert by mixing 1 tsp of ea into 1 gal water but I did it 2x in a row. BEST WAY TO FIX THIS ???

Leaves turning a yellowish color
My plants are turning a yellow color. The two in front were shorter than the one in back, so I raised the two in front 4" so they all received the same amount of light. Any ideas?

Overwatered cubes in hydro? Too close to the sun? or effect of having add
Hi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes. Did i manage to overwater some of these plants by having them too close to the net pot?
