This is be far the worst effected leaf... at the moment & has occured since plants have been under 400w in the last 3 days.
The leaf tissue between the veins extending from the midrib has dryed out & on examination is brittle & cracks in places once pressure is applyed !
My first assumption was Heat Stress, but their is no curling up of the lamina - the blade of a leaf.
This lead me to believe it may be nutrient burn ?
Hence i come to ye the grislyed old forum veterans of many a grow seeking wisdom 'n' advice of Fuzzys fcekd leaf problem.
