Your temps are OK. Towards the end of flower you will want to drop your humidity so you don’t get bud rot. Keep your fans blowing oscillating on them.
You can download a Flora Trio feeding chart and just follow to one for photoperiod. I may be wrong but I found no chart for auto flowers. Week 7 calls for 1000 to 1400 ppm run off. I am wanting just a hair higher to be aggressive. Taper off to nothing but water last 2 weeks to get all the nutes out.
I will adhere closer to ppm numbers on the Flora Chart more towards end. I have messed that up before myself and did not finish correctly. Chem bitter slight after taste.
Water to 20 % run off and don’t let your fabric bags sit in tray water overflow. Get rid of the run off.
