Do a good flush with ph7 water...what nutes ya using??? what strength??? back off the nutes for a week or so, then introduce them in diluted measures,like 1/6th recommended dosage.....If thats nute burn on your leaves theyll quite prolly die off, best to wait for more leaves before flowering..if you need to keep the plant short, try some very gentle Low Stress Training..search fo LST in the forum and you'll get different techniques, i use wool to slowly pull the stem over...do it gently and a little each day or so or you'll snap the stem..you can also train the plant to lean over if you position the lighting to the side of the canopy, as the plants canopy will always grow toward the light..
LST should help keep it short.
or you could top the plant...this will concentrate growth to the sides..Also what lighting ya using?? does it have enough blue spectrum light???
GOHYDRO- how close is your lighting???
Plants usually stretch due to lighting bein too far away...also certain deficiencies can cause stretching too..
I just posted looking for an answer as to why my babies stretched so much. Mine are beautiful but are causing me serious problems due to their height. What system are you using? Hydro? Aero? Soil?
