Weird formation on fan leafs

After flushing and changing the reservoir cleaning the pumps this problem has only progressed to the point I'm quite worried and in need of opinions options. This is starting from the bottom and is only effecting the fan leafs at present. I did a search and looking around and google images but could not find anything that resembled this I can't seem to embed so used a 3rd party image hosting
Any ideas, opinions, cures!?Cheers in advance

Looks like molybdenum def to me I personally have never had it. You need more pics with hps off people hate that and won't help so I suggest you get them into some better lighting and people will help.

self bump, I looked around at molybdenum def but mine doesnt seem to fit the bill, what with the crisping leafs which are really light in color, perhaps whatever is doing the damage is causing a nute lock as well. Any other help + cure would be appreciated!

Sometimes a N deficiency will manifest and show in this manner. Usually in the mid and lower growth. You probably also want to look into a P deficiency as it can also cause red/purple tinting of the leaves. Usually in the upper, newer growth.

A molybdenum deficiency is very rare but is more likely to occur in color changing strains and in cold temp conditions. The only time I saw this in my garden my ac timer broke and was shooting cold air all the time. As the deficiency progresses towards the shoots the new leaves become distorted or twisted. Also causes leaves to have pale, fringed, and scorched look along with retarded or strange leaf growth. Older chlorotic leaves experience rolled margins stunted growth and red tips that move inward toward the middle of leaves. Looks like your leaves exhibit these traits described but just an opinion.

What about ph, what is your ph in the soil. I had a plant do this last week, it was a week or so away from harvest so I just pulled it and hung it. I later realized it was ph issue I corrected but did not give it long enough to take hold and fix problem. The buds were almost ready and I did not want to lost them.

beuffer hmm I do have an intake blowing right on them from outside so pretty cold air. This could be it? My PH is about 6.0, I did have some PH issues earlier about 3 weeks ago. dropped right down to 3.5 but caught it and fixed that, the new growth seems decent it's just the lower fan leafs that are showing them weird formations. I've since turned off the intake and just relying on the outtake fan to keep temps down now. See if the problem stagnates

After some research and close inspection this may indeed be the case. Some of the first fan leaves have rolled margins upwards and I did keep my intake on 24/7 so as soon as lights went the temp drops right down. Plus the low pH I had some weeks ago would of locked molybdenum. I've now also got my intake off and I'll see if the problem resolves itself. Is there any nute/remedy I can use to fix them up to good health or is it just a case of correcting the mistake and letting it fix itself?
