Auto and regular plants in one box.
I got an auto plant in a box, waiting for flowering to start very soon. Light schedule 20/4. Now I planted a new photoperiodic seed in a same box. What should I do, keep the 20/4 light schedule before the auto plant finishes and after change to 18/6? Or change it right now?

NEED SOME ADVICE! Change to LED from HPS? which ones are good for tent size? Which ones are good for good yields?
I've got a 4x4 tent with 8 seedlings in cups but will be in 11L pots. Currently I had a 600w HPS light but my ballast busted today. I have a back up CFL 150W not to mess up the light schedule. Thinking about changing to LED lights, I know it'll be cheaper but I want same yield...

Will this one be too hot too?
Do you guys think this light will be too hot for my tent? Will it be ok, or bad? Maybe 1500w is too much? Or will the plants grow faster? shorturl.at/grtFL I had to make a short link to fit in question

Veg/Bloom switch
My plants are 5 weeks from germination, I have flowers and buds forming but I am starting to worry they aren't growing as they should (I want them bigger). I have had my light veg and bloom switches on throughout. Would you recommend I change over to just bloom switch now?

Should I flip?
I’ve got my plants in 2gal fabric pots and I’m not planning on transplanting up. The plants are averaging about 8/9” and I’m starting to see small roots out the bottom. Should I flip to flowering, or can I get away with another week of veg?
