No Growth after nutrient lockoutI had nutrient lockout due to using full strength nutes instead of 50%, after thoroughly drying pots for a week. I Flushed each plant with 5 gallons of water then I added back nutes at 50% minus calmag & boomerang Still no growth in a week and stems are wreaking, new growth twist5y ago

Leaves bent downToday after lights turned on I saw all leaves of my plants looking down.
I watered them one time in two days (day watering/day resting), the temperature wasn't too high (27°c max) but there was colder this night (near 17°).
Also, I added sulfur 2 days ago to low my ph.Week 6

Lamp distance to canopy, dialing it in.I usually use the manufacturer's recommendations on lamp distance from the top of the plants/canopy, but its different for some cultivars. Some need a little more distance at 100% some can take it a little closer than the recommendation. What signs do you look for to dial it in?Week 12

I’ve got photos above of Plant C- super curly leaves, they develop brown spots, then dry out/become crispy and I remove them. This moved top to bottom of the plant in 1 week. Deficiency, toxicity, root rot? Plant continued to grow vertically but buds have stalled out. Help!!!Week 7
