Brown spots

Hello everyone, I have to ask the same question, since that problem is spreading although I give her CalMag. 9 days ago only 2 fan leaves had those brown spots, now almost all of them are affected, especially higher ones. I wanted to feed her once again and then start flushing

Verge of leaf burn reminds excess of potash. Calcium and potasium correlate , blocks each other if one is in excess, then you overload other, but it cant be absorbed and you have new problem from corecting old. Check ph, most common. Feed autos less, they dont need so much food, plus soil is always full of goodies. She has still 4 weeks, so you have at least 2 weeks of feeding from looking to diary. You never flush in soil. You just stop feeding at final stages, but amount and regularity stays same.

Plus you dont get notifications if anyone mentions or reply. Platform has chat. Right bottom corner, press arrow. She is very far from harvest. At least in diary photos. Dont believe breeders recommendations. You can feed her few times still. Ph would be two letters constantly repeated if i would wrote a book how to grow weed in soil. Ph is everything here. Then goes rest. Autos dont like many food. Excessive nitrogen, potash, and many more complicated relations can block calcium absorption, but wrong ph is most common mistake, then goes overfeeding. I would do two plain waterings for her, with 6.3 , dechlorinated wateter. Only after 9-10 days ( or what ever it takes for 2 wet/dry cycles ) i would return to feeding. Want to be on safe side, add 0.5 ml/L of calmag to second plain. Thats what i would do. Honestly from look she has 3 weeks, maybe 4 till earliest harvest window.

Hi, Looks like a pH issue that is blocking Ca absortion... Adjust the pH to 6.2

AsNoriu, thanks for you answer. I use PH perfect nutrients, so I never check PH level and so far everything is ok (that's my second grow). That's what I mean when I say "flushing", I just wanted to feed her tomorrow and then after 4 days start giving only "flowless finish" for 2 weeks. What do you think, can this problem affect the endproduct or am I close enough to harvest, not to worry about this? Слава Україні! btw, is it ok that we are limited in letters when we are asking questions, and then are unable to comment on our own questions? I think that's a little weird.
