Looks like some heat stress and over-ferting.

How often are you feeding them?
What are the temps in the closet?

You should fill out the nursery questionare, mods will prob. move this to the nursery.

temps have been as high as 35c but ive not got it down to 30c but thinking of getting rid of box and just using wardrovbe.
I used some 'baby bio' 10-1-2 a week ago, then 3 days ago used some 7-7-7, apart from that water every other day (about 1 litre) with 6.4 ph water.

i would let the soil dry out completely before water.... use ph'd water for the next few waterings... after a good leaching... run about 5 gallons thru the plant medium, get the nute burn out. then proceed with water to let the plant regain normal processes.. mj plants like consistentcy... so grow formula for veg and seperate formula for bloom.... good luck...PEACE..

and im not sure what C equals to but good temps are 70-85 ferenheit any higher and the plants suffer stress.

Moved to the Nursery.

Copy and paste the Nursery Questionnaire and answer as many questions as best you can.

Actually, here's the soil portion:

Soil Growers:
1. Are you growing from seed or clones?
2. How old are your plants?
3. How tall are your plants?
4. What size containers are they planted in?
5. What is your soil mix?
6. How often do you water and what type of water do you use?
7. What is the pH of your water?
8. What kind of fertilizer do you use and what is its NPK ratio?
9. Do you foliar feed or spray your plants with anything?
10. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights")
11. How close are your lights to the plants?
12. What size is your grow space in square feet?
13. What is the temperature and humidity in your grow space?
14. What is the pH of the soil?
15. Have you noticed any insect activity in your grow space?
16. How much experience do you have growing

I'd say get rid of the box that it is in so the air can move around the plant.

Temps need to be a bit lower, and you might be able to solve this with a big box fan to get it down to a manageable level.

Stop watering so much and chill on the nutes for now. On the next watering you might want to flush the soil good with pH'd RO water. The soil should be completely dry before you water each time.

Trying using nutes every other watering and start your nutes at a lower strength to see how they will handle and slowly step up.

could it be heat stress? the curling and burn look like heat stress to me

only you could know how hot it gets in there to say if it could be heat stress

also could be potassium as the edges burnt on some leaves, could be another def in there too...

EDIT: looking at the pictures of the whole plant looks like nute burn also as the tips are burnt lower down

i thought it was either nute burn or heat.
Ive let her go dry nearly bone dry now.
and ive managed to get the temps to a steadier 28-29 degrees (84.9 farenheit)
if the new growth starts looking ok, im gonna go 12/12 and only use 'biobizz' bio bloom

Or both
