lollipopping and trimming in weeks 5-8?

i am a new grower and am in week 6 (day 36) of flower. this is my first grow and i have 4 1000 watt hps lights, 36 plants (18 Abusive OGs 18 NY sour diesels) in 5 gallon buckets with coco perlite. i am currently watering them at 1400ppms with a 5.9-6.0 ph every other day, NO CO2. my first question is do my buds look normal sized or are they small for day 36? and my second question is about late trimming or lollipopping. i am in week 6 i want my buds to grow as much as possible. I have a lot of foliage so taking away smaller branches and taking down a lot of leaves seems like it would help the plant concentrate on producing more bud BUT at the same time i am afraid to strip them down and put them into shock which can backfire and slow down bud production. also i used Big Bud by advanced nutrients from week 3-6 as stated on the bottle but i was thinking should i keep giving them big bud or stop. if anyone has any advise or pointers on how i can finish off strong please let me know

Sorry for the sideways pictures

I always get my training done at least 1 week before flipping.

I', hard headed I took a few leaves off,will not do it like that again. I think people that know what they are doing with it come out good. I ain't there yet.Lollipop works,but I don't know when to do it.
Looks like they doing good as far sideways as I can tell. You can tell I don't have a lot of experience,someone will come along that knows something.
GL&HY!

I flipped your pics for easier viewing.

They look good Btw.

thanks for flipping the pics!!

They look pretty good at this point of the game it might be risky to start stripping the plant. But it would definitely help the buds if it doesn't shock your plants first.

how far away are your lights?

some are taller than others but id say they are about 18-36" from the light
