my room will be 2x2x4(h)
10,000 lumen per square foot for flowering.
2x2 = 4 sq ft so a total of 40,000 is needed for your space. So a 400w would be perfect/ a little overkill as they usually do around 50,000 initial lumens.
5500-6500k for veg
2200-2700k for flowering
whats your opinion on lumens for vegging brother.
Prolly 35-40k
I dont know what jacks classic is but looks like your feeding to much it got to hot or the PH is to high or low. Got any more beans?
Anything above or under those temps and they grow real slow and adds stress to the plant.
Get some carb board and double sided tape and make walls for the sides and back and your finished.
