LED used in Veg growth... no limbs??

[shondo]

I am currently vegging plants under an Illuminator 90 W LED, in a 2x3' room, using a 3 gallon pot, lights are about 12-18" from top of plants (depending in strain), 4 plants per room, water ph 6.5, soil ph 6.5.
I have good height growth, but the plant is not producing limbs. Could this be a nutrient problem? Plants otherwise look healthy.
Any suggestions??

If they're seed starts then they typically don't branch out unless you force them to. Pinching top growing tips can force apical branching.

What's the lumens on that bulb?

I keep a 400w hps 12-14" away from my plants, I'm sure you could be keeping a 90w LED much closer. I have a feeling what you have going on isn't growth, it's stretch. How bout a pic?

Sounds like another satisfied LED customer to me......... 1) lower your water to 6.3 if in soiless soil. 2) I believe a lot of this is strain specific- some strains put off a lot of branches, others don't. Pinch the growing shoots to help branching but with LED's, don't expect much anyways.....

Agreed.
