Leaves have turned rusty

First of all: DO NOT CUT HER DOWN!!!! You will definitely regret your decision if you do so! ...soooo, I just had a rough look over your diary and feeding, as I am using BioBizz aswell and I experimented a bit with amounts in the past. Right now, you are definitely feeding way too much. It's hard to overfeed with bio nutes, but I managed to do this with BioBizz aswell. If your 4ml/l is correct, its too much. You shouldnt even use much BioGrow this late into flowering. Also, the tons of Bloom you are adding leads to a Potassium and Phosphorous toxicity. The runoff pH is to be ignored when using BioBizz (thats what I learned for myself). The input pH of 6.5 to 7.0 is perfectly fine, if you can, try to get it to 6.5 but BioBizz regulates itself so dont worry. By the way, the leaves that have the spots on them look like potassium deficiency, my noobie guess would be a nutrient lockout due to way too much phosphorous (and nitrogen). My recommendation would be to just water plain water pH'd to 6.5 until the plant finishes. It's probably gonna get a lot worse over the next couple of days if youve really been feeding that much (bio nutes need about 72h to show their first effects), but like I said, just add pHd water without nutes and let the plant and soil work things out. You'll see in maybe 1-2 weeks its gonna fatten up and more and more hairs are slowly gonna turn amber. More and more leaves are gonna turn yellow and fall off (thats intended). Just dont add any more nutrients to the amnesia, you would make it worse. And for the Blue Bullet and Blue Cheese, you definitely need to reduce the BioGrow, I personally would leave it out completely, and also reduce Bloom and TopMax. You can decide if you go another week of feeding with 1.5ml/l bloom and 1.5ml/l topmax or just plain water. I would do plain water for all of them. They all seem to have a serious nutrient overload. Hope I could help, if you wait it out youre still gonna have a wonderful harvest, just be patient and dont harvest early, youll have shit weed if you do ;) Cheers man
