Stalled finishing

This is my fouth grow and my indica dominant strains have stalled big time. It is over 12 weeks for a 7-8 week strain (NL X BB) and bud formation looks good, but they will not finish. The plants are getting plenty of light, but temps are high and humidity is very low. These are things I cannot address in my current situation. It is being grown in perlite with generic nutes. She is 31" tall with a 21" budsicle and a scrawny, pencil-sized stem. The attached picture was taken two weeks ago and little has changed.

I have been making the nights even longer (14-16 hours) in an attempt to get her to ripen. Any other ideas besides being patient?

Put the lights back down to 12/12 immediately.....Now how about a super dose of Molasses or a bloom fert with mucho P and K? Roots over 85 and the cannabis stops growing. Can you cool the roots? I dont' know your temps.

high temps are most likely the problem. looks like some real potential there. harvest it already.

I figured it was probably temperature. Outside the house it has been over 112F for a month. The house temp is about 81 and with the lights and such jammed in a 2' X 2' space with a small fan it is about 88-92.

I have some fresh seedlings getting ready for the fall/winter season in another area. When they are ready for the 'main grow room', I will harvest her and her sister no matter what. Until then I will only use ice water to see if that helps even slightly.

no ice water will shock the roots. You can harvest early, it looks ready enough. Cloudy is fine

My brothers greenhouse gets over 100 degrees with no ill effects, my grow area right now has been in the 90's for over a month, cement slab with moveable containers.

That is the key,cement slab it is like a big heat sink....or cold sink depending....stores lots of energy
