Day 35: White widow max auto and White LSD auto updates & questions

[Gaigenale]

It's day 35 from seed now on these white widow max and white lsd autos from MSNL. Running a few different LED's in here a 2000w cannalight, 600w mars hydro, and another 600 watt cheapo. The white LSD plants are just finishing pre flower while the WWMA are on about day 8-10 of flower. Curious to see which plants do better as the WLSD had a longer veg phase. Using a soil mix of 2 parts promix 2 parts Happy frog 1 part perlite 1 part worm castings. Currently the only additional nutrient I have given these plants is foxfarm big bloom and i'm curious if it's time to switch nutrients on the WWMA now? I have been watering with rain water so i'm not PH'ing my water very often but last time I did it was right in the money at 6.5. While I think the plants look pretty healthy and have responded pretty well to the last week of LST, I assumed they would bush out just a bit more in the veg phase. My lights I started at 24" above the plants which quickly became difficult with the larger colas wanting to constantly reach out to around 1' from the light even after redoing their LST constantly, I have attempted to keep the canopy even though. My other issue has been that during the day even though I am running an AC unit in the tent, it will get to around 90-95 degrees for an hour or two and then I turn the lights off and the temp goes down during the hottest 6 hours of the day, though this has been the most efficient way to keep the tent cool it definitely keeps the tent about 5 to 10 degrees over where I want it to be during their last few hours of light and first few hours of dark. There is not much more I can do to effectively bring the temperature down any farther so I'm hoping it's not affecting my results too much. You can see the power of the WWMA genetics as they blow past the other strain in the veg phase and right on into flower in just over 2 weeks, I ultimately wonder if this means I will get a poorer product off the slower grower but i'm not sure. This is my first grow so any help or advice is much appreciated!
