Maiden voyage

Had to leave town last week from Tues - Sat. Came back and Critical Kush looked beautiful and happy, starting to flower. Zkittlez had grown much more veg and was stretching up towards light. Seemed to be getting close (15" or so from top of plant to light) and looked kind of droopy. Raised light thinking I might be burning, but after a few days she doesn't look any better. I've been on a 2x light nutes schedule (Cyco Grow A + B for Zkittlez, 2 ml of each; Cyco Bloom A + B for Critical Kush). Watering using blumats seems to work great.
