Do you think it has a deficiency?

Wondering if any experts can tell me if she is a bit deficient or all ok She is about 5 weeks into flower. Also, not 100% sure of the strain so if you have seen similar I would love to know. Cheers

Lighting? Medium? Nutes?

LED - Samsung + Meanwell = 2.7 umol
Coco mix with some worm castings
Currently, just bloom and some calmag no more than 500ppm (as I got nute happy and burnt the tips a while back)

I ask because it looks like you're getting some light burn. How high are the lights?

Yes, thank you! Very low actually (maybe just less than a foot). I was trying to maximize the sugar. Should I back it away?

Definitely. Tips burned and curling up, cupping of the leaves. Definitely light burn. Not saying there isnt more, but back those lights up. 18 inches should be enough.

Probably a good idea. also looks a little pale green. maybe a a little nitrogen if it isn't getting any.

Righto, I will whip out the tape measure, many thanks for the advice. I will make adjustments now. After I burnt it with 'bloom' nutes, she stopped drinking water completely and the pale green set in. I flushed heavily and allowed to dry out. Now she is having half dose of Fertz and water ph to 6.2. Today was the first time I noticed the RH rise sharply within a few hours of watering. So I think she is drinking and perspiring again. I will provide a little nitrogen tomorrow.

yes deff feed some nitrogen, you have another 5 weeks of flowering yet
