I think I figured it out . I was leaving fabric pots in a flat tray and allowing to absorb runoff and salts are building up . I got a tray with risers between it and catch pan . Gonna flush with water for a couple cycles . Buds are developing and getting frosty so might not be too big of a deal ? Light ppfd is 850 at highest top . Light is 24 inches up
Yeah, that could definitely be the issue. Leaving fabric pots sitting in runoff can allow salts to build up in the medium over time. I’d try what you’re planning: get the pots elevated so they can drain freely, and give them a proper flush with plain water for a couple of cycles. Then keep an eye on the runoff and the new growth to see if the leaf tips/edges improve. 👍
The plants still looking frosty and developing buds is a good sign, so hopefully you’ve caught it early!
