First indoor grow

Yo all! Lol. So my first indoor grow. Im using mars hydro tsw2000 in a 4×4, temps 20/4 light cycle, temps 82 with light on 71 with light off humidity stays around 50-60%. I have 4 golden goat photos that i plan to put outside that are 3weeks old, 1 blue dream auto thats 30days above soil and g13 photo thats 27days above soil.. Using fox farm warrior and happy frog mix 50/50 with added perlite, roots organic cal mag and earthworm castings.. Been alternating feeds recharge/mammoth P every 2weeks and using 1/4 to 1/2 of fox farm mixtures every 2weeks big bloom and grow big together.. Using well water and 6.0-6.8ph.. Any suggestions? How should i be feeding the auto as you can see its pre flowering and has been since 18days old. Started topping g13 week and a half ago and just topped goldent goats. Only doing lst on the auto...

Fr yall im a newb to indo and ive only had a couple successful outdo grows literally 2 like 10 years ago lol.. Idk wth im doing for real lol.. Did some research just kinda threw some stuff together and trying different things lol.. Do they look good? Im open to criticism and any suggestions on different things. Should i get another light? Is my g13 going to get too big for the tent to put into flower by the time the auto is done? Do autos need 12/12 cycle during flower and when do i know to change light cycle?.. When should i stop lst? My first auto also. I think i went in over my head for first grow lol like idk how having a photo in the tent with auto is going to work out lol.. Help me! Plz!
