heat stress?One of my top cola doesn't look that good

Nearing end of week 4 and one of my top colas to one of my plants looks rather yellow and not as developed as others, it's one of the taller ones does in the room, does it look like heat stress, running 600w hid air cooled

Since the rest of your plans are shorter, put it in a corner so it's not directly under your light.

Got a few tall ones mate, this one was central of the light but have put it to the side of light now, wasn't sure if it was heat stress, but lower down on that branch buds look good

Nice grow

Cheers mate, second grow n have my fingers crossed all Gos ok

Netting and supercropping.
