you should be fine.. ive had 4ft plants in 1.8 liters and they flowered fine, go figure. it is a weed after all


looks like a homebox tent. the best

also looks like maybe your on the verge of over feeding & heat problems " tips start to dis-color"
im looking at the orange pics, the tips are starting to show signs, and a few of the edges of the fan leafs are wilting under.. "heat"

im assuming your using a HPS (looks like it anyhow) whats you setup

you need some fans, intake & out-take. aka inline/outline or just regular fans rigged to suck cold air in and blow hot air out.

open that big square flap, and stick a fan in front of it blowing up. then mount another fan in the roof or up high, sucking air out.
