Welcome!

Looks good for 7 hours of light :thumbsup:
Nice strains as well!
How old are they? any signs of sex yet?
What soil are they in?

They are startin to take on a lighter green color, and since you havnt fed yet, its definitely time for some nutes.
I use FoxFarm's Trio, which couldnt be an easier line to use. But there are lots out there to chose from..
-Feed every other watering.
-Let them dry out before watering again. I let mine go a little limp-leaf'd to let me know they need water. Or sticking finger in the soil an inch or so by the side is a good way to tell moisture.

Looks like there's more than one plant in the longer box; Keep one plant per pot next time.
-also a good rule of thumb for soil is 1 Gallon per foot of anticipated growth. 3-5Gallon pots usually yield decent sized plants.

Good job with the green house, has it been used the whole time?
-Also, kinda looks really wet inside, are there holes anywhere?

Hope you get some Fire! Ill help where I can. Good Luck man
