First Time Grower Would Love Experienced Opinions

Dude they look stellar. This is your first grow right? My suggestion is to ditch the CO2 attempt, up your RH to between 35 and 40. Keep the extra amendments around for feeding later (as teas). Kick back and observe!!!! You're really on track to have a good successful grow the first time. I can promise you that you will NOT get the strain dialed in this grow. Instead, concentrate on seeing what happens this time and keep tweaking the method as you learn. Find a "strain" and stick with it, getting it dialed in nutritionally and get to know that plant.
As for nute burn, the bat guano is about the hottest stuff you listed. Feed them as "teas" later in the grow. They are all good.
PS, I run 3 1K lights over the flowering table and they are right at 22" off the tops. With the A/C system I think you have, you can put them however close you want!!! As long as they don't bleach out. Lamp heat should NOT be one of your probs.
Do you have any strains you recommend. I'm interested in dj short blueberry but i have a few veg and clone closets so id like 2 or 3 strains eventually but will def stick to 1 next time

So do you recommend never switching just 100% of grow use both?
All personal choice, and it won't make too much a difference overall, but enough if you want the most out of your plant.
This is how I'm doing it right now.

MH/MH from Seedling to week 4 (I veg for 2 months, every time)
MH/HPS week 4 to week 8 of veg
MH/MH or HPS/HPS Week 1-2 Depends, do you want to minimize stretch, or let them do their thing. I use MH/MH on Sativas and HPS/HPS on Indicas.
HPS/HPS Week 2-4 or 2-5
MH/HPS for the last weeks

Dual spectrum gives them the best of both worlds, and as a bonus the MH UV spectrum in flowering makes the plant produce more trichomes or bigger trichomes to protect itself from the harmful rays.
As for humidity, I personally keep it as low as possible the entire grow cycle past the first set of true leaves. Lower the humidity the more/bigger resin the plant produces.
So I would say no for a humidifier.

You can check out Advanced section, probably a lot of good threads on ways to make cannabis force more trichome growth. Just be careful, I know there is a thread on UVB lights, they cause cancer, but have been proven to work. (Cancer part is contact constantly, most people set them in the grow rooms and have a off switch outside the grow room so whenever they go to check they turn it off first to minimize risk)

okay thanks I'll just do it how I planned then, I def don't want stretching so maybe next time I'll do more time of mh and not add a humidifier. Thanks for all that info I love it!

I wouldn't recommend the humidifier in flower. During veg, yes, maybe, but during flower you want to keep the RH below 50% I personally like around 35% to 40% RH.
