what am i doing wrong? am i going to lose this harvest? should i harvest early..

im tripping help guys..

Are you sure your only on the 6th week of flowering? They look older to me.

I actually am not sure if they are about to hit week 7 or 8.
i thought i wrote it down but i might have done it wrong

Wait a week, don't stress you will still have good meds.

#1: TO HOT!!!!! Even when running gas (C02)and adding silica I won't run temps over 85!!! C02 and adding silica will allow plants to be more heat tollerant. Even at 80deg a Marijuana plant will SLOW down growth rates!
At 90 deg your plants go dormant! No real growth happens. your plants are freaking out and trying to finish as fast as they can (looking to pollinate). This may in turn cause herming!

#2: The pics show plants trying to transpire, but not doing well...see #1

#3: Add CalMag as they show a need for more, but again #1 is involved.

Now then, others are correct. Your meds will be ok, and NO don't harvest untill tricomes begin to darken. You can adjust and do better the next grow.

You are lucky that the heat hasn't killed the roots and thus the plant.

Good luck.
