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?

GreenHillZoneanswered grow question 4 years 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.

Yellow leaf tips in flower She'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?

Dry leaf tips Over the past four days, the tips of the leaves have begun to dry out, what could be the problem? The 300w lamp shines only 75% at a distance of 50cm. My second ceyote plant feels very good under it and has no problems.

Defoliation late in flower on Auto's I 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!

Flush?I have never tied to flush a plant and I seen if the leaves have too much yellow then it is not a good idea. I plan on doing a harvest in 10-14 days and wanted to know if both of my plants should be ok with a flush.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency? This is mostly on one spot near darkest edge when tent closed. Thanks!
