Nutrient burn?
Stonerdanswered grow question 4 years ago
Can't really determine what's going on from the picture but from the diary it seems like your plant suffers from a Phosphorous (P) toxicity! - top leaves grow thinner with interveinal chlorosis while Calcium (Ca) and Magnesium (Mg) deficiencies are showing at the mid-bottom of the plant.
I'd suggest lowering the "Aqua-Flakes B" dosage by half and checking it daily for any improvements. If the problem gets better then keep going until she looks completely healthy then start increasing slowly as the plant matures, if it doesn't get better then try flushing your system and providing her with tap water for a couple of days to clear out the toxicity (this may cause deficiencies of other nutrients so be careful!)
Hope this helps! Good luck and happy growing :)

980ppm is high for that size of a plant . Dial it back a bit and growth will increase . I'm coming up to mid flower and the plants are at a decent size . But they're only getting 1.4 EC. less is usually more .

It's looking like a little nute burn from the yellowing tips. Maybe back off a little and should be fine.

Yellowing on leaves tips. Should I start feeding her?Some yellowing appeared on the leaves this last day. Temps and humidity are controlled and ok. I haven't been feeding her, she has been growing on light mix for the past 25 days. Im thinking its time to start applying some nutes. Or could be something else? Thanks!

What gave this? Light excess or nutrient burn or lack?I had this symptom from the beginning, stable, I didn't worry too much.
What could be the reason?
How to avoid this in the next grow.
I mean, it's minor, but might be better to attend and unleash a better result.
I have this on all buds, on canopy it comes with curly leaves.

Possible nutrient burn ?I’m pretty sure this is nutrient burn but it’s weird because I’ve only given a tiny dose of nutrients so far. Less than a quarter of recommended dose and probably less than I’ve ever given an auto before. What do people think ? Nutrient burn ?

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.
