Hi Oscar
Still working on it. It seems to be only one res causing trouble. This is the second time this set up was used. The first time was meh. There was no Scrog and it really took a chunk out of the yield. Buds close to the lamp were awesome, but any distance over 6-8" was all "popcorn".
Never one to talk trash on a fertilizer company, This is also the first time advanced nutrients has been in the mix. Using the PH Perfect line is real hands off stuff, just put the mix in and leave the PH/ec meter out. Its a real "trust us not your expensive meters" situation........so it will take some getting accustomed to. Good thing I have medicine for anxiety.

The reservoir is changed weekly as per instructions. Top off with 1/2 strength base nutrients. NO PH UP/DOWN!!!
