Strange for sure. Doesn't look like there are any deficiencies in the plant.
Changing nutes is the best thing to do for start off.

Would say there's a lot of excess leaf you could defoliate a bit.
Could be it's in the plants genetics other than that maybe another can shed some light on the problem

The leafs are twisting in the 4th picture it might be ph, have you calibrated your ph meter recently? I’m no hydro pro but if I was going to harvest in a week or two I wouldn’t be feeding anything

I haven't calibrated recently no actually, but hopefully this tank change will help. I assumed they were twisting as i added a new light, and theres just no space left!
1-2 weeks is a guess, my magnifying glass should be here this week so once i know for definite I'll lay off the feed

Low potency, weak terpenes, low yield. The only thing going for it is the exotic appearance and pretty pictures. It's Instagram weed from before Instagram was a thing. There are a couple of popular crosses with it, but I'm pretty sure they aren't much better and people just think if it glitters it's gold. The hash wasn't much better. The trichomes lack the bulbous heads, they're mostly hair like.

I see, thanks for the reply
Purple is certainly pretty but not for every type of user
