tall plants

Start bending it and tieing it down. Also what nutes is he using, I use a three part and when it starts to get too big I cut back on the grow nute. Not all togther as it contains the nitrogen but I cut way back like half to a third of what it needs. But tie down for sure little bit each day so he does not break anything.

so what i did was get some hemp string and tie them down.i did this a lot sooner that the stage u are in tho.if u are in tent and u have a plant getting too big its tuff.one thing u can do is get rid of one or 2.also i would have done this sooner too.if one is streaching real bad them u can supercrop it to stop upward growth.if u tie them down(low stress bending)colas will form down the stem and grow up.be sure to allow for growth in the stem so dont tie tight! make a loop or something cuz it will cut thru stem as plant grows.in a tent if they get too close to light the nugs will foxtail and not finish out so plan ahead nex time and u will have shorter fater buds.this grow might be a wash tho.600w lights dont have much light penetration, couple feet,so keep them short from the begining.also try to pic short strains.if u grow from seed then alwase remember all the same strain will grow diferent so pick out small fat plant and clone it so u have all same hight.

no no dont tie them down yet. you say 7 weeks so say 4 week veg 3 weeks flowering. they might have just finished there stretch and will very little or grow no more at all. could you put up the info on how long veg ect ect. as you might be ok
