the og kush, ive got the tips of the leaves curling down, i had some light stress, that ive sorted, now its about 60 -70% humidity in flower, what ive learnt should be 40 -50 % humidity in flower, im about to use a dehumidfier to try sort that out in the next day or 2, nitrogen ?
You definitely have a phosphorus deficiency the purple is a great indicator of such if you Google it, you can compare the colors,
First, balance pH (Hydro: 5.8, Soil 6.0 - 6.9) or re-apply nutrient mix if necessary.

Nitrogen toxicity causes leaf tips to curl down and claw. Also Shiney leather like leaves. Plus the deep dark green is most obvious sign. It is not phosphorus related. The amount of green in your leaves tells how much nitrogen is in the plant. This was one if the first things I learned 3 years and some change ago when I had same issue.
this weeks been better since i sorted the light stress out after not turning my 4x4 og kush tent light back to the timer for flower , had it going 24hrs, so there getting into the flower cycle now, ive notice 60-70% humidity i have learnt should be 40-50% in flower, so going to add a dehumidifier tomorrow hopefully gets it to the ideal humidity, also the leaves are curling down so might be ph levels, might be nitrogen levels, im using an anarchy organic nutrients one of their product line that balances out nitrogen amongst other things so hoping that works as i need to collaborate my ph pen to start getting involved in my ph levels abit more, that i know is extremely important, other than that if i sort out my leaf curling down i think my plants look alright and have good structure , might hold some weight. The pennywise in the 70x70cm tent looks too be going well im really happy with it and the temps are real good, tops seem to have a good strength to them so looking forward to see how nice the kolas are and how full, its a strain i bred myself so looking forward to the end results
