I have about 3 weeks left of flower, haven’t sta...

Winged_Growerstarted grow question 6 years ago

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?

I wouldn't introduce more/new nutrients this late into flower, especially since your plants look pretty good overall. You could try and reduce your day temp, as 1 of the benefits of calcium is help the plant handle heat stress. Hope this helps. Good luck and happy growing! 💪

Dark green leaves, check; clawed leaves, check; burnt tips, check; interleaved burns or peeling, check. What you have is nute burn, mainly nitrogen excess. Just for reference, cal / mag issues are present several weeks before showing symptoms, if it were that, there would be no point to give it at this point. Stop feeding and give the plant water only. Next time use an EC/PPM meter, they are a great tool in preventing over feeding.

Brown leaves and red stems. Is this a calcium deficiency ?I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!

orange sherbet crispy leaves. Close to harvest Fastbuds Orange sherbet first grow. I already harvested this plant but I’m curious what the issue was. The leaves were yellow and crispy to the touch. Other leaves looked fine. 2.5oz harvest but it dried really fast(7 days) and now smokes harsh. Don’t want to repeat this mistake.
