Yellow/Brown/Spotted/Crispy Lower Leaves
What is wrong here? Gave an extra dose of nutes but the problem only seems to be getting worse and spreading up the plant. Definitely effecting the bottom leaves more. Others said to just increase N-P-K ration, but this seems like something specific.

I'm using a coco mix with advanced nutrients organic. I water 1l everyday with little to know runoff.The new growth is a lighter green and the leaves are thin. Is this some sort of deffinency or toxicity? I recently just flushed and stared giving half nutes.

To defoilate or not to defoilate.. that is the question!
I've always heard that you shouldn't "defoilate" auto flower cannabis, especially if they're a sativa to boot. With that being said, (looking at my pics for reference) should I do more defoliation? Would doing so really increase my yield significantly? Thanks

Are we growing on track?
Thoughts on my grow at the end of week 2? Am I on track? They seemed to be a bit stretchy don't you think? With my cool tube installed planning on dropping them 30cm/1foot away from my plants. The leaves feel some what rough any suggestions. Please like, comment and follow 🙌

What should I do next?
Was reading 1870ppm at 5.6 so i flushed 20L water threw till I got 6.3ph and 950ppm and let dry. Feed the other day 4L at 50% nutrients strength 840ppm and is seems it's gotten dramatically worse since then. Before it was very slowly getting worse. Worse at the top now too.

I'm not sure what's going on, but the tips of several leaves are twisting over and/or turning white. I don't know if it's a nutrient deficiency, nutrient burn, I don't think it's too much heat, but maybe due to sun burn? I'm not finding much luck about white leave tips online.
