First Grow, Very detailed with pics, having problems!! Help plz

I recently had a friend finance the nearly $6,000 bill to get all the top of the line equipment and I put it together in a 10'x8'x8' by myself. I don't have anyone that I can both trust knowing about my grow, and willing to help me with the little details I haven't learned yet. Here is what I have currently set up, then I'll tell you about the problems I'm having next.

• 4 quantam 1000w ballasts inside of a/c hoods
• active carbon filter at the end of all the a/c hoods
• all of them piped together with 6" ThermoFlo tubing with (2) inline jetfans pumping the air up and out of an old chimney
• I have the ebb & gro system with 40 total pots connected
• for the medium, I have about 3-4 inches of hydroton at the bottom, with a layers of canna coco and layers of perlite (i'm retarded, should have mixed them together, not layered separate)
• this is located in my basement room adjecent to my bedroom
• using all canna products, currently on veg at 24 days from transplant
• currently at 900ppm with canna coco a&b, rhizotonic, and cannazyme in my 50gal res.
• the big bushy ones in the pictures are Green Crack, the smaller ones are blue dreams and grape punch
• I can only water them once a day because the medium stays so frikken wet and get's mold on the top layer if I do it 3-5 times a day.
• I have two oscilating fans
• With the ballasts running 50% it stays 75 degrees, at 75% it's between 79-81 degrees and at 100% it gets up to 85-87 degrees
• humidity is at 50% and varies by 10%
• I'm getting an 80mg per hour ozone generator next week for mold and smell
• the ebb and gro pots were not fully draining so I put all of them on 1" x "6 boards, now less water is sitting in the bottom

NOW FOR THE PROBLEMS

• Temperature, I have to leave the grow room door open otherwise temps are pushing 87 degrees, what is the max it should be??
• The leaves are starting to get little spots that are growing bigger every day and turning the whole leaf brown/yellow
• little patches of grey/white mold keep appearing on the soil, I['m not able to water more than once a day
• the stems appear to be reddish-purpleish in color
• do you think it's time to flower?

Here is all the pictures that I have taken for you to better understand my situation.
