It could very well be from the light too close... check your RH and let us know though. Because low humidity and high heat would be a culprit there. What's your temp?
I don't see anything that even remotely resembles a Mg problem; you would have to get better pics of the leaf surface to diagnose that anyway.
It's not overwatering though no worries on that one.
Hello again Stinky.

Well as I suspected its low humidity (30) bought a dial today and as you say high temps aswell 85f

Its got me puzzled tho,my new rooms 6x6x7 intakes 6" and extractions a 5 and 6 inch fan i thought 11" extraction would handle it without any problems,how wrong was I...i had to pot up today to 6.5 ltr pots and in doing so i added a 600hps to the 400hps i was using so 1000wts in total now and still hot,I know its been around 80degrees outside today and im drawing that in thro an open window,just cant understand why my extraction aint taking as much heat out as i expected?

As for the humidity ive stuck 2 10lte buckets of water in the room,but i cant see any difference on the dial,any advice is welcome and thx for your time again in replying,its very much appreciated.
