Sorry for the late reply. Night shift worker
Problem: Leaves are curled up and slightly rolling. One leaf has split. The worst of the curled leaves feel a bit dry to the touch.
Medium/grow method: Biobizz Light-Mix / extra perlite Using 3 Gallon smart pots
Feed: and supplements used: Mostly water to this point. Have added some Bio Root from General Organics. Very diluted. 1 ML per 4/5 Gallon. Added this when I first soaked the soil for planting the seeds.
water source: Using a RV filter to remove chlorine. Water tastes great, so it is working to filter the chlorine. I admit I have not been pHing my water. Water does work well for growing other plants (non-cannabis)
Strain/age: Plants are around Day 11 on the pictures. 2 White Widow Auto 2 Nirvana AK-48 2 Nirvana Bubblicious (I know I went a little overboard with the strain types for my first grow, should have stuck with just one strain for ease)
light used: Using 3 LED: CREE CXA3070 3000K Roleadro COB Led Grow Light (Cheaper Amazon lights. Went in with my dad on the costs of the setup, he knows Amazon and was the best lights I could convince him to buy)
Climate: Temps around 75-79 F Humidity has been around 47-54 %
Additional info: Around day 5/6 while I was at work the duct for the AC unit actually popped out of the window and off the unit itself. Was cycling hot air into the room. Not sure how long it was like that, but when I got home the tent was around 100 F. Fixed the issue, although the soil did not look too dry I gave the plants a decent watering fearing they got scorched. Plants did not start looking curled however until several days later. Not sure if this is related.
I have since backed the lights off a bit, around 5-6 inches and have even turned off 2 of the 3 to see if the plants will uncurl a bit. Lights are 28 inches from the top of the leaves. I also gave them their first heavy watering (with some run off) Any other suggestions are welcome. Thanks for the information thus far.
