Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

Dark tips
it seems to me that the tips of the leaves have a very dark color, it looks like an excess of nitrogen but in three weeks I have never fertilized and the only additions to my biobizz light mix are a sprinkling of guano kalong and 10% of worm humus biobizz.

LEAFS DYING
The edges of the leaves are dry and black. Every single point of the leaf is burnt(black) or yellow...even some edges on the leafs of the coal are burnt. I guess it’s overfert...but I just flushed. Is it Ph? I haven’t checked in awhile. Is it they ready to be cut down?
