I checked a bunch of nutrient deficiency tables and found some Boron deficient pics and they look similar.
The Tiger is 2-8-4 and I have only fed them twice since flowering 9 days ago. Actually looks like a little too many nutes. Just gave them plain water today.
I'm actually pretty sure that I may have some fungus or something from the fan I put in there last nite. This just happened overnight> Sux!!
couple more pics...stuff is mushy, then gets dry and breaks!!
