I’m growing in FFOF soil and saw recently some holes in my bannana k and blackberry k. I’ll show pics of the problem and notes I take for feeding. ive only been using recharge and cal mag with every feeding. Keep in mind I sprayed them a week ago with peppermint and today with lavender, idk if it’s a pest issue.




Are there more and more white spots appearing on the leaves each day?
ph is fine, idk about sulfur, the ffof soil should be good with what’s in it, the only thing I can really think of is some kind of pest issue. It’s a tent in my closet with no windows and I have to open the closet door to let fresh air in. I’m thinking the bad ventilation is causing one of these asshole pests to show up.
I've only seen leaves like that for three issues, pest, ph issue, or sulfure. There could be more but those just what I've seen. I'd get a magnifying glass and take a close look at those plants, leaves top and bottom, branches, crotches, and also get a pH and ppm of medium.
@mwhite9829 Could I get your opinion on this one. I'm at a loss.
That second plant picture. Check under your leaves. See if you have anything living underneath and dig around the surface of your soil a bit.
How far are your lights from the canopy?
Edit: what's your rh?
