Nutrient burn or light damage?
GreenHillZonestarted grow question 4 years 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!

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!10 months ago

Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Yellow leaf tips in flowerShe's pretty far into flower, in DWC, and the environment and nutrient schedule have stayed consistent for a while now. I'm using GH Flora Trio at 5ml of Micro, 2.5ml of Gro, and 7.5ml of Bloom per gallon.
The leaf tips are looking burnt, should I ease off on nutrients or what?

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

The bottom leaves on one of the plants are turning yellow (starting from the tips) and slowly dying , while the top leaves tips look very burnt.
