[thc is good for me]

MH lights arnt very good for budding you should use a HPS if you can. 90 deg is too hot without co2. You should also buy some nutrients that are for growing buds thats what i did and i didnt have any problems.

IMO man you neeed to lower the K and boot the P and make sure your tops isnt too close to the light, heat can cause yellowing too. Its still early in flower so again id say get a HPS bulb and toss it in the color spectrum is needed now. Might wanna get an extra fan or 2 in there to move some air around while your at it, 90 is a bit too hot when your not using CO2.
