ok im going to try;
flower or veg?
ambient air temp?
cfm intake?
distance from light?
soil temp?
newt temp?

80deg to high sir,
need to drop to 70 sir,
key rule stay within deg operating temp day/night

they look dry in need of soil flush with 3oo pmm and some good old fashioned clean air, need flushed almost three days to bring back from such stress.
this dry wet extremism plants develop bamboo like stems when this happens all-tho it promotes extremeness in rapid up take it also needs water more often than normal almost everyday 1-2 cups. this bamboo like stem can be beneficial in its treatment and maintaining growth, but its not advised to practice method to much stress. hope i helped
