The Three Amigos

1/22 flushed all three plants with florakleen and then immediately fed afterwards. Runoff from NL and FO ph 5.8 ppm 573. LS runoff ph 5.5 ppm 650 1/23 plants look great after flush and really started to drink up. Increased canna coco a+b from 9 to 12, reduced calmag from 6 to 5, increased canna boost to 10. Ppm up from 900 to 1000 6 1/25 backed nutes down on canna ab to 11ml total ppm 950. NL stretch appears to be over, no new hiegth achieved last 48 hours. Tent extension was wrong kit, had to order the right extension and delivery time frame is 5 to 15 days. Keeping eye on top branches, one NL branch is and has been 11" away from the light. No evidence of burn. Viparspectra recommended 24" but have read multiple sources of people getting them as close as 10" with out problem. I never go more than 14 hours without visiting this grow room and have my eyes peeled for light or heat stress. 1/27 backed a&b down to 10ml. Saw some signs of tip burn. Looks like 950ppm is what they like right now.
