Bellamy - XXL Critical Auto First GDGrow

Her buds are forming nicely and starting to fatten slightly which is good, however, I can't pinpoint the issue with the leaves. I've tried allsorts and just can't seem to resolve it. Some of the last week the temps have been high so that's caused a few issues but the apparent deficiencies have been ongoing for a few weeks. Still, she's growing strong so I'll carry on trying to sort it and see where she ends up.
