    Default PLEASE HELP!!! Sulfur or Boron deficiency, or what else...??

    Hello everybody, this is my first post on the forum. I do it out of an emergency issue. The branches in the two photos are from the same plant (the third one showing the second branch sideways), which is a Blue Cheese (Dinafem): as you can see they are strikingly different. The one with the white hairs it's ok to me, it also smells fragrant and starting to bud with abundant trichomes on leaves. The other one looks very bad, and most of the branches of the plant is like this: hairs growing already dark red, few perfume, and few or no trichomes on leaves. It began flowering some ten days ago, at some 40N latitude. I read extensively on diagnosing the problem, and guessed it might be sulfur or boron deficiency. I would exclude boron because I watered regularly, the pH is ok, and climate is not at all dry. There are also here and there random leaves cupping just a little bit (not pictured). I have available boric acid and Epsom salts to fix the issue if there is one, or I'm only being paranoid? Many thanks in advance to any who could help.

    I'm growing outdoor. The plant is quite huge: it has grown from seedling to a 60x45 inches oval plant much trained, in a 30gallon pot, from 20th may to today, and it's still growing a bit, many many leaves. It seems at first glance a wonderful healthy plant, well green, no yellowing leaves. Last week there was a row of 4-5 days of very humid climate.

    Hi ban taku, would you be able to get some close up shots of the 'nodes' ..between the brances of the plant you're worried about?

    The closer the better, as stable as possible.

    Next time you feed her, add some of your Espom salt to the mix. I think that will help. Looks like it could use A little N as well. JAO

    I don't know if I quite understood what you meant, as yet, first thanks very much Hotshot! I will add Epsom salts next time. She has still some 40 days to go: can I rescue her? and second here are some more pics.Click image for larger version.

    I am feeding her Plagrom 100% Terra Bloom with this N-P-K composition, 2-2-4, last time I gave her some 6/7 gallons of water with 5ml/L of such nutrient. Could this be too few N?

    I have sprayed the plants some days ago with an organic product against caterpillars who left those white specks, being made of rock dust who obstacles their munching. I found it looks awful, and even though it would not leave residue, I won-t use it anymore....

    I also have treated her with pyretrum some time ago, because there were some spider mites affecting it, but after that no new symptoms of infestation appeared.
