I think this is happening because your lights are too low...

If any of your mid canopy leaves have this discoloration, that it may be from too much nitrogen.

But, Im willing to bet its because of the heat of your bulb.

G'luck

I know how you feel...

I initiated flowering when some of my girls reached about 30"..LOL!

I think Ill just barely manage it.

Make sure you have an oscillating fan swirling around in there...

It will help some.

Usually, Mj plants stop stretching around the 3rd week..

Yeah they should stop stretching soon as that stage of flowering will be over. They will start filling in the stretched part with tasty bud

yup i have a oscillating fan blowing on them, my garden gets no hotter then 80F. as far as head space i guess i'll have to deal with it when the time comes i guess. lol

so ya think its heat stress then? does nute burn only occur on the tips first?
