Veg lighting approach? Switching from cfl to hps?
I started my second grow a couple weeks ago with a 130w cfl in my 1m veg cupboard. I’m thinking I will make the switch to a 250w hps soon. I don’t want to overheat the space. Do you think this is a good strategy? I’ll flower the autos in my 1.4m tent with 600w hps.

Discoloration and patches on the top sugar leaves
Leaves circled have gone lime green to yellow with the dark and light spots shown in the image. Is it light burn, wind burn or something more sinister?!

Leaves "praying" after lowering the lamp
I am in week 4th of flowering Laughing Buddha, 220W LED ~60cm from tops. Today I have lowered the lamp and the leaves started "praying", on one (higher) plant the other, mostly-indica Holy Punch seems unaffected. I am curious, is there too much light or sweet spot and it's good?

Side lights ?
Would my plants benefit from these extra lights hanged to the side? Photos included of light and how they look. Above are two SF1000D lights. Curious if these will help the under growth or if it's just a waste? Thanks for any info anyone can share . Happy growing!

Distance from plant to lamp
I’m growing under a 200W LED light... how close to the light should the seedling be? Right now it’s just about 90cm / 35 inch away from the plant.

Starting photos indoors for June transplant
Want to start photos on a 14/10 schedule in April to match the lights around June 1st. Can I grow my babies on a 14/10 indoor schedule or could that possibly induce early flowering? I would rather not slowly adjust down from 18 to 14 before Xplant as suggested otherwise

Longer Light Cycle - Mid Bloom
Is changing the light cycle of an autoflower from 18/6 to 20/4 in mid flower too stressful? Doing so would bump my DLI enough to keep my existing light through harvest. She sleeps like clockwork but less so now in mid flower. Will she adjust in a couple days to a longer day?

Temperature VS More Light which is better for buds size and potency
Should I continue to use two LEDS if temps are reaching 87f during flower (day 1) or just move plants more towards center of tent and use one LED for better temperatures (75f) (only growing two plants). lights are 1000w bestiva and are in a tent that is 24"x48"60".

I think its to bright and to hot, seeing some taco leaves. Sanlight on 100% for few days, temps go up to 32C Next plan is to add BB Grow,Bloom,CalMag,TopMax,BioHeaven,Activera,Algamic no Canna Mono Mag anymore. What do you guys say to feed? Light back to 80%? https://growdiaries

Lighting schedule?
Many references state the when moving from vegetative to flowering stage the lighting schedule (indoors) needs to be reduced from 18-20 hours down to no more than 12. Why do many here stay at 18 or more the whole way through?
