Plant dying and I’m not sure it can be saved. 2 plants in a 2’6" x 4’ space in 3 gallon felt smart-pots. I’m nearly positive that it’s root-bound due to amount of roots that I see on the outside of the felt (or maybe that’s how it’s supposed to be? Pic will be attached). Exposed roots have started to turn brown where they had been white before. One plant (first plant) has always been a bit ahead of the other (second plant). First is the one that’s dying, but I’m starting to see early signs of the same yellow leaves on the other. The second also is showing tips of leaves curling up, which is a brand new symptom as of today. Buds are firm, but trichomes are all still clear. The pH soil meter was reading about 7, but I don’t know if it’s reliable. Yesterday, I flushed with 4 gallons of 6.0 pH water. Run-off was about 6.5, so it appears there is some kind high pH condition in the soil. I suspect that the same condition the first plant is having, will appear in the other if I don’t act. Using General Hydroponics nutrients.
So I’m not sure how to proceed. I’m lowering the nutrient pH to 5.5 to compensate for the high pH condition. Unfortunately I didn’t check the soil pH until too late due to the nutrient pH being automatically monitored and adjusted to 6.0. Hopefully one of you pros can give me some advice that will help me keep them alive. The two photos that show a relatively healthy plant is the second one that’s just starting to show symptoms. Thank you in advance.
