Thank all of you for the responses. I was wondering what was causing the downturned tips as well and the Nitrogen was most likely the culprit of the tails: I added fresh water to the fill line and it dropped tds to 703 in both reservoirs. I’ll purge and fill tomorrow and use 1/4 strength maxibloom and 10ml/gal of florabloom to keep the nitrogen low without sacrificing the PK. Also will continue 2ml Si and 2ml Signal.
