What deficiency is this?

This is my second grow ever. On my last grow I had a Mars hydro 2000. I kept the same distance plant to light distance even though I upgraded to the MH 3000 this time. After looking at the plants more and reading these responses I realize my light was wayyy to close to the plants. The actual buds are still covered in resin and the under leaves are surprisingly healthy but the top fan leaves are fucked. I raised the light and the plants are gonna get flushed over the next 2 weeks before harvest. Thanks for all the responses, much appreciated everyone 🙏🙌

Oh yeh, is your water quality hard or soft?

Alright mate, what happened between weeks 6 and 7? Looked lovely in week 6 then on 7 it turned into one of the ugliest plants I've seen in a while lol, joshin pal. So what did you do on or after week 6? How was your feed/water regime? It went down hill fast so at first guess I'd say lockout, but lets hear about what you did from when it was lookin good, to when it started lookin like shite.

I guess potassium is too much for your plant Leaf is important if it dies, the plant can make banana sacs naners to survive My suggestion: you can spray biobizz algae mic or seaweed, prepare 2.5 ml for 1 liter of ph balanced water, wait ten minutes, open the mouth, then spray before bedtime or an hour before waking up as a possibility, otherwise the energy will go away.This is just a suggestion I use it constantly Even if it is not a problem, my leaves usually shine and photosynthesis does it easily and it keeps insects away.

I ph my water to 6.5 every time I water and I gave a half dose of cal mag and a 1/4 dose of reefertilizer bloom on 3 occasions. I feel like I’ve taken it very light on the nutrients but maybe not.

Mine started to look this too after a I feed them too much PK, check your pH next watering. Maybe it's a lockout but I don't know just want to share my opinion.

It seems she is fading but It is too early. Happened something similar to me, found out I was giving more nutes than what she needed. Whats your feed and hows the rh?
