If it's only happening on the top-most exposed leaves it's light bleach. If it appears on leaves further down it's N def.

It could also be mg def. And LED can be a contributor to that. But, it doesn't look blotchy enough between the veins.

The buds should be ok. Just raise the light. I had bleaching at that stage and it seemed to go away by the time I harvested. (I had the tip of a bud bleach in late flower and that didn't go away. I discarded the affected area when I trimmed.).

I did let water sit out for 3 days but i say there was so much in it it did not matter, just mu luck

If your plants are behind in flower it might also be cold temps. Just throwing that out there. I learned that the hard way. Like a lot if things. Just found light leaks after my new grow room settled.:dunce:

I have bleached my plants, with a T5. Yours look nothing like mine did. Bleached is bleached as in the leaves turned almost white. Mine happened early when the plants were about 15". They fully recovered.
