Do you think temperature is too high for this first stage? It’s about 28 degrees with light, and 18/19 in the dark.

Veg cycle-Blooming
Hi I ordered a mars hydro ts600w which is arriving either today or tomorrow. I also ordered light timers which I just switched from 24hrs to 18/6. My white widow is currently 5 weeks and my Alaskan purples are 4 weeks. I was wondering if I could start flowering by next week?

Can rotating my 12 hour cycle back a few hours over the course of 3 nights harm my plant mid flower?
If i were to manually flip my lights on and off an hour early for 3 nights to adjust my 12/12 from 9am-9pm to 6am-6pm would it be detrimental to the plants? They are in the 5th week of flower. Rotating back 1 hour each night

PAR/PPFD and light height
PAR/PPFD: does light height matter if your PPFD is in the right range? Another way to ask: is 300 PPFD @ 2 feet the same as 300 PPFD @ 20 feet, or are there other factors involved? (assuming heat, C02, all other non light inputs equal)

18/6 leads to high temps in small tent; change light schedule or stick it out?
Girls are at 18/6 and 3-4 hours before lights out the tent gets up to 90 degrees and humidity can’t compete. Should I wait it out or try 16/8 moving towards 12/12 close to flowering (autoflower). Will lowering light exposure affect yield more than high temps would at 18/6

Swapping lights during flowering
Do you guys think that swapping lights at the late flowering stage is going to harm my girls in any way? Been fortunate enough to be able to order myself a Viparspectra xs4000 to replace the v600. And as I understand it should be quite an upgrade. Thanks for any advice!
