I started a PILE of trees indoors this over this last winter. Everything was going great until I started fertilizing them with some high nitrogen bat guano fertilizer that I inherited from a friend. They've been on a steady decline since.
I applied the guano as a fresh brewed tea twice over the span of two weeks.
Once I started seeing adverse affects, I flushed everything thoroughly with tap water and pruned back any bad looking areas.
It's been about two weeks now and they seem to still be on the decline.

Any experts in here that can help? Thanks!
