Good question Xarn,
how's your stuff setup, lights fans tent size etc.
the info will allow people to Dial in on a real problem to help you.
I think you are fine, put a fan blowing on them lightly to strengthen stems and stick them under your MH.
re-pot, bury deeper like suggested and Be Careful not to burn your plant, I did to my first which I finished last month.
back of the hand at the distance for 30 seconds to really feel the radiant heat.
if it's uncomfortable for you it's the same for the plant.
sort of a balancing act, to far they stretch, to close they burn.
I check my plants daily to make sure my light distance is OK.
Spek your a Hoot!
cant laugh Hard I'm in pain.
2 new blown discs last Monday.
L2, L3 burst inward, I took a ride in an Ambulance and 14 days of pain later I'm still in pain.
Thank God for my Jars full from my 1st plant.
oh and pain killers and muscle relaxers too
Sorry to to steel thread OP, I had to spit that out!
