Leaf tip brown and curling under, sounds like overfert to me frenzi, the feeding schedules are only guides and have to be adjusted to your particular plants situation (age, lights etc). I'd flush and feed with 1/4 strength nutes next watering.
hudson88 Reviewed by hudson88 on . Plant Tips Browning? Ok so my plants have been under 12/12 since 7/2. I watered with the FoxFarm TigerBloom and BeastieBloomz accordingly on 6/30. Now my plant tips have started to brown and curl under. I was wondering if it might be because I over-fertelized or what? I used the FoxFarm soil schedule on their website. Maybe its jus cause the plant is not used to the ferts yet. Maybe a N difencey? Thanx in advance for any advice. Ill post pics when I get my camera back. Prolly tomorrow or Wednesday. Rating: 5
