Just updating, yesterday I did another water change and let the PH do it's thing, watching to make sure it didn't exceed 6.5. This morning I tested when I woke up and both tanks were borderline 6.5. My tap water tends to have a PH of 7.3, and my nute solution always tends to swings up. Last week I let it swing on its own without interference and it stayed in the 6.3 range. This morning I brought both tanks down to about 5.6, and based on what I've seen the PH will gradually climb. climb. The yellow tips haven't improved, but all new growth seems to be very healthy. Main problem I am having is humidity. RH in my house is about 60%, but I've managed to bring the tent down to 59%.
these are my observations this week, please provide feedback if you see fit.
P.S. I've added 2 nets and defoliated the bottom 6 inches of each plant slightly.
