Ive been adding MAGpro at pretty steady doses however not calcium at all.. (Except for whatever calcium is in my bloom food) could lack of calcium effect magnesium uptake? ..(noted that my ph has been between 6.2-6.7)View attachment 2616046
I would say so
Yes its mag def. Just add Epsom salt to a spray bottle of water and foliar. Epsom salt Imo is the best thing fo mag and also has sulfur and oxygen.
Those are not 1.5 weeks from harvest.
And I dont think that is an Mg deficiency either.
right i understand that some of the leaves are going to yellow but this is like a severe fast progression from top to bottomdude its flowering, some of the leaves are going to turn yellow. if you are about to harvest, you need to flush anyways. Epsom salt will definitely help, but i wouldn't want that on my bud. it will wash off though, so just be sure about a week before you cut it, THOROUGHLY flush the entire thing out. you dont want to blaze up chemicals.
Well... What do you think man? Harvest date is april 30th. So yeah i guess 2 weeks and 2 days
well it actually looks like a mg def although IME, Mg def will start more in the middle of the leaf and work its way out. Also usually accompanied by brown spotting and/or brown tips. Could be N as I notice very red petioles (leaf stems). If it is only affecting the newer leaves, it is probably Mg. But then you say you are adding an Mg supplement so its either an Mg lockout in which case, more Mg will only exacerbate the problem or something else. Bleaching?
There is really no such thing as a "harvest date" unless it is one arbitrarily set by the grower. Harvest when the plants are done, not by when theyre supposed to be done.
