Near harvest deficiency

Outdoor 5 gal container grow, 7th week of flowering, unknown bagseed, and ive only fed it distilled tap water its entire life with NO problems.Last time i fed flowering nutes was 13 days ago because leaf tips resembled those of lightly nute burnt ones. so i flushed with more distilled tap water and the problem is worsening. The spots are really only effecting the top fan leaves of every cola. all the other leaves look green and healthy I know plants leaves die during flower but this doesnt look to be of that nature. i was told calcium def but i disagree. These spots look more like manganese def spots. Seeing as though i have maturing buds of unknown genetics and i dont know how much longer i have to flower, what do i do? should I treat it or am i too close to harvest for that? I have analyzed my trichs and pistols and it seems as though 30-40% of my trichs are milky white yet only 20% of the pistols have browned and retracted so i literally still have no clue how much longer i have. i have included picture of spots and buds to show you how ripe they are. Im afraid to feed it nutes for chance of nute lock.

that is cal or mg. probably CAL. Distilled water does not have ca/mg in it. Lemme ask you, why not use your tap water? If you PH it it ought to be fine! Also, on those spots is it kind of like a rust, does it rub off?




EDIT: You're certainly closer o harvest than you were a week ago, however; i'd say you have quite a bit of time left on those gals. Just saying.
I'd look into the detrimental effects of harvesting early. You've come this far... DO IT RIGHT!!!

Heya Hiram....I wouldnt worry about the spots...most likely a result of the mild nute burn. PLant is looking freaking awesome!!! cpl more weeks looks like

Pistils will do that as the plant matures. Im pretty sure that is a CA deficiency, when you distill the water you remove these trace elements that your plant actually can benefit from. I do hydro DWC and I use tap water. Straight out the faucet no letting it sit. Just PH adjust to 6.5 for soil and 6.0 for my DWC getup, my plants do fine. Yours ought to as well.

If youre hellbent on using distilled water, invest in some Ca/Mg.


I wish you the best!!

just a little cal mag, youre at the stage where they start fading anyways... looking great! dont stress.

maybe one last boost, but no more
