Nirvana master kush and og kush auto 600w grow

Hey everybody the grow has been going great using general hydroponics nutes in 3 gal pots. Only vegged for 3 weeks in the greenhouse before bringing them into the 4x4 tent then switch to 12/12. No lst or scrog this grow. And been flowering with a MH. I have a hps and I know that's best for flowering and I have used hps every other grow to flower would it have any effects this late in flower positive or negative? Plants are 5 ft tall including the pot. I'm going to post the latest pic how long do you guys think untill I'm ready for harvest? I know another few weeks at least just wondering if anyone sees something I could be doing better. Constructive criticism is welcome

Hey there, looking good. The only thing that worries me is the heat coming from your cool tube light without an exhaust hooked to it.
Happy growing!

Okay so here are a few more pics taken from a few days earlier. And alitttle more information, they have been in flower for almost 4 weeks. I use a 6 inch 440 cfm fan to pull air from the cooltube with one end open and the passive air intakes on the bottom open using the negative pressure to create a vacuum airflow. I have a few 55 true watt CFLs in there for supplemental lighting. The whole room my tents are in has its own dedicated window a/c unit. I run the lights over night from 9 p.m. till 9 a.m. to keep the temps lower and have to run the a/c less as it's summer here. Have no heat issues to date even when I did run in the day time just easier load on the a/c. Stays pretty constant 70 degrees with lights on or off. Haven't been monitoring humidity tbh. I feed 6ml of bloom and 4ml of micro every 3 days as the master kush are heavy feeders. pH of 6.0 No nute burn in sight. The og kush auto has been handling the same feeding even on a 12/12 flower schedule and has kept up in size with the photoperiods. But buds are definitely smaller and maybe just farther along, although quality seems to be next level. Overall Nirvana has never let me down on quality. Any advice is appreciated.
