-P.S. - I change the nutes/water in the entire system ever 7-10 days depending by switching the hose connected to the pump and just pumping it all to my bathtub...then i re-fill and yada yada...and bam! consistency like you've never seen before! I also check the PH everyday, which seems to go from 5.3 to 5.8/5.9 in one day, which is good, that means they are eating, but you need to set the ph in the auto-topper res. to about 5.1/5.2 to accomadate this swing....plus i auto top with half strength lucas veg nute formula...i use lucas veg nute formula for flower and 1/2 veg for veg...works just as good and conserves nutes.

Reg lucas formula is GH Micro/Bloom: VEG 5ml/10ml
BLOOM 8ml/16ml
(where 5ml = 1 teaspoon)

** Ok, now we can move on....
