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?

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.

White leaf tips and spots? Help :(Im using spring water from a mountain near by,but it is pretty acid (~4.8 ph).
Could that be the reason my plants have white tips and a spot on the leaf? Or could it be the height of the light?
I will raise the ph to about 5.5-6.2 ,so hope for better results.
Thank you :)![[First Grow] RQS Q1 organic](https://bucket.growdiaries.com/static/post/photo/65797/3062838_ef9716894eff05137e1c440f793ba7b0_m.jpg)

Nutrient lockout or deficiencyThe plant in the picture has been light for a few days even though I fertilized more last time. I watered with EC 1.5 / pH 6.2. The runoff came out at EC 3.5, but there was only a little runoff, so I actually find 3.5 to be okay. The leaf tips are noticeable, though.

Classic N toxicity (:Heyho :) since she has progressing leaf tip burn and curled tips which I'd almost certainly say is a nitrogen toxicity, would you recommend going down to 50% general strength or maybe leave out the grow supplement at all and just feed Bloom? Cheers guys :)6y ago
