If week 9 of flower this should be part of plants natural process of fading. Fan leaf on the second picture looks like there has been a HR (hypersensitiv Reaktion) going on. Nothing to really worry about, could plug it off just to make sure. Gotta say that she already looked quite pale in week 6/7 should consider give her full feedings next time with a base nutrient. Only seeing additives in your schedule. During week 4-7 you want to push your plants giving them all building blocks she needs to build up mass.

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance.
Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

At what stage do leaves get darker ? This is confusingI overwatered them at the beginning of veg and then I fed them with 0.7 ec nutes max, EC would go up if I gave more.

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.
I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?Week 13
