have a few questions to ask the experts

Hello all. I am new to this and I was wondering if you guys can help me out in a few fields of expertise.
My first question, I am growing Larry OG, Pure OG, OG kush, Lemon, ghost,sour kush strains. I have heard these are the best in CALI . I dont want to lose these guys by screwing things up so my question is I have my grow room so seeled that the room temp hits 90 + degrees during the day, also the light cycle is off during that time but, is that too hot for them during the night cycle ? is it stopping growth during those temps ?
My second question is I am currently in my veg stage , week 2. I am using Sensi grow A & B. I Am using 170 ppm in my second week in veg, should i be giving them stronger doses at this point. The tallest is 12 inches already, and I feel like they should be getting more but I read somewhere that you should only be feeding them only 1/2 strength, until week 3, then thats when you start giving them the full strength. I am so confused when it comes down to PPM. Please advise me and give only your best and honest opinions to help me have a great first harvest.

Ya can increase the nutes slowly and see how they like it. If they are green they are growing. Bigger the plant the more nutes they can take.

I understand that, I really want to give them more but my friend told me to go by the book your first time in order to not screw up, it states on the sensi grow site stating I should be using 1/2 strength during week 2 veg. I really want to give them more but I am not in the position to take chances here. These plants are the best money can buy around here. So you see the concerns I have.

man I would never let it reach in the 90's... ever...

I know what your saying smokingbot but they arent effected at all by the heat as far as I see, they arent wilting, they arent deficient looking, no discoloration at all, they are really nice considering the temp. My main question is will it effect my yield or flower stage or is it stunting their growth.
