Nutrient burn or light damage?

GreenHillZonestarted grow question 6y ago

Burnt tips appeared around week 3. I think the bio tabs are a bit too hot for this plant. The plant is growing at a good rate so I don't think a lockout is occurring. Burnt tips across most of top of plant. Could this be light damage? How to proceed or do I even need to worry?

GreenHillZoneanswered grow question 6y ago

this is my own grow. I don't think this was either nute or light burn. I am using the Biotabs starter pack, and I believe the yellowing tips are a result of my failure to include BACTREX in the growing regime. Can't say for certain but my light levels in terms of PPFD/DLI have been ok, and there has been no nute lockout that I can see 7 weeks into the grow. Thank you smoke24 for your assistance!

Your light is too close, back it off 10 inches. Happy growing.

Early nite burn?Hello! I've noticed that many of my leaves have burnt tips. I first noticed this about 3-4 days ago. Since then, more leaves seem to have this but the it hasn't gotten worse on individual leaves. Could this be nute burn? Thanks in advance!

General Plant Health Check In Are these yellow tips anything to worry about at this moment? I noticed slight Nutrient burn on day 25 and lowered nutrient concentration which seems to have stopped it on newer growth. Anything I might be missing?

Nute burn? How to handle?Hi, i guess i made the typical newbie mistake and over-feed a little bit. The plant started to get some brown/yellow tips, mostly the upper part of the plant. Is it enough to just stop with nutrients and stay with clear water or is there anything else i can/should do?

Rusty spread mid flower…What really causes this rustyness to slowly creep and cover the whole plant sometimes, and sometimes plant only partially affected, always in midflower. I know the obvious answer being calcium/mag but even with increase in this there is oftn no change or noticeable slow in spread

Some very little holes appear after feeding them, and maybe after I spray them with water. Could it be some light burn on the spots that some water bubbles had stay for long? Some nutrient burn?
