helk me

I WENT SHOPPING $540. I got a 400 watt Extra Sun Power box for my light. It switchs from MH And HPS with the flip of a switch. I got a $90 Mh Light and a good HPS light. That crumbled thing u c is one of my babies who didnt make it. Right after i took this pic i found another dead one. I got 16 left to hope for. Well i kinda have a problem. Im in my mid second week and i just switched from CFL to MH and now my temp is way to high. Its at 84.0-87.2. I have a Fan blowing air down onto the plants and a fan blowing air across the plants on the ground. I have my Mh light about 1 1/2 feet away. Should i higher my light? or will my babies strech to much? and i am using BLACK GOLD soil and now i have 30 days before nutes run out but wut should i use first? FOX FARM- GROW BIG or FOX FARM- TIGER BLOOM. Any critisaim is well thanked for you guys have helped alot.

help me plz

first of all black gold isnt really soil, its worm shit...84 degrees isnt thaaaat hot but youd easily be ok with it 2 feet away or even more especially at this point, and dont have the fan blowing on them too hard

well, if you still plan on vegging I suggest using the grow big first....the Tiger Bloom is geared more toward the flowering phase.

get a glass enclosed reflector and use a separate in-line/vortex exhaust fan to cool your light.
