You need 400 ppm 0.8 ec right from the start of their lives. 5.8 ph, use vinegar until you receive your ph down. Increase feed 100 ppm 0.2 ec every week after you see new growth start. Cheers

Hello community! I broke 2 branches this week. The first one happened by accident when I was draining the runoff, and the other when I was bending it.And today I came across a video where the author explains that silica can cause brittleness of branches. Does anyone have experience with silica and have you experienced anything like this? I add potassium silicate with each watering, at a concentration of 15ppm

Accidentally poured 2mL of "Grow Big" into "Big Bloom" bottle.I absentmindedly put 2mL of FF "grow big" directly into the bottle of"Big Bloom" (the murky one with bat guano).
Is there going any type of reaction that will create products that would be unsafe for my plants? Haven't taken chemistry yet. Is it ruined?

Why is my PH possessed?Why is my PH refusing to go down from 9s to 6 unless I quadruple the normal amount of apple cider vinegar to 12ml? Normally 3ml does the job. This week, ml somehow doesn't move the needle. The EC is a little higher, could that be it? The RO is normal starting at 8, this week 10+Week 6
