Glookies.

Found the tallest plants (which are only 8inch from light with a ppfd of 1500-1600) the leaves had started to yellow. Moved left side up to max height for my space (11 inch ppfd 1200). Also found my root zone was ph6, my meter isn’t the best so ran some water out the auto pot through my bluelab probe and it was only 5.8. Pretty low for flower so put them on plain PH’d water 6.4 over night to boost it up. Took the opportunity to do some much needed maintenance. Drained and cleaned main tank. Definitely not running carbs next time. The gunk was really bad. Had to clean and flush each autopot float system. Everything nice and clean for last half of flower. PH 6.1 PPFD 900-1200 (on canopy top) EC 1.9 Humidity 65% CO2 1200-1500 Thanks for stopping by ✌️🏽
