Hey y'all, due to recent humidity issues I started pulling back my nutrient schedule for the girls, in fact I pulled back on watering altogether. I've been able to bring it back under control now and will be looking at getting a bar heater within the week, but now I've got this fuckup to deal with. So, I usually give the girls 3L each 4x a week, but had to cut that back to 2x a week with the humidity. The issue is I premix my liquid nutes in a container, usually this isn't an issue as I empty it after the third or fourth feeding, but I may have let it sit for a week or so this time, the pH rose to 7.2 and I didn't check it for the last two waterings. I'm in week 5 of flower now and I have a few rust colored leaves on one plant with burnt tips and margins across all three. Ive already watered with correct pH and nutes twice, What should I do next?
