Dman3000's first 600W grow

Hello everyone this is my first official grow and I put alot of money and time into it. I have them all growing in one of those lightproof Homebox tents; with a 600w MH and will be using a
600 HPS for flowering. There is a 6" carbon filter in it as well.Also I have the light in a air cooled hood connected to a 435chm exhaust fan (which also has a diy duct muffler connected to it). Inside is completely white for reflection purposes I am using fox farm nutes(growbig,bigbloom,tigerbloom), but have only used growbig with a little of bigbloom as its still in veg stage.
Now on to the plants. I have about 5 different strains growing currently.I have 3 Diesel Ryder plants, 4 Female Cheese from greenhouse
1 Unknown sativa strain from swagbag, 2 Critically Smashed and 3 white widows. the 3 white widows and sativa plant have been vegging for about 2 months so far and I
plan to put them into flower at the end of these week as they are starting too get a little too big.I'm going to build a separate veg room this weekend out of Rubbermaid container and cfls. Im going to put the cheese,critically smashed in here until the others are done in the flowering room so ill have two harvests.Im going to keep the diesel ryders in the flowering room under the 12hrs of light as I feel Ill get me weight out of 12 hrs off hps then 18 of cfl lights. Im thinking I will definitely have to tie down the sativa as they are
known to grow taller and I only have a 7 foot home box with about a foot and a half taken by the filter and light.the 3 WW and sativa are also in 5 gal container and were transplanted a week and a half ago
into Foxfarms happy frog soil. these 4 are very vigorous plants and have shown little to no nute burn throughout they're lifespan. The biggest widow has yet to show any burn.
The diesel ryders are about almost 5 weeks into growing and are starting to show lots of flowers and look pretty healthy(the smallest one get a little nute burn but has bounced back).
I transplanted the biggest one into a 3 gal grow bag last week (filled with happy frog soil), and plan to do the other 2 lowryder this week (does it matter since it already has started flowering?).
The 2 critically smashed are doing fine no since of def. but Ive yet to know they're gender.(there's all female except for these mystery kids). I get them for freebie from the doc so I decided to give them a try.
Now on to the cheese about a week ago they started to yellow, now a few of the leaves on at least 2 of them are COMPLETELY YELLOW, just take a look at the pics. and also a few of the upper leaves on the same plants have ALOT of brown spottish going on.
I know for sure root bound may be a factor if any else can chime in on these. For instances yesterday morning I notcied one of the roots in the cheese starting to going UPWARDS out of the soil. I put a little dirt on top to cover it up but I think that this is a problem thats has to be dealt with.
Im goinng out of town a few days but when I come back I plan on tranplating ALL of the cheese into 3 gal containers of happy frog potting soil and watering with regular phd water. hoping this helps.Temps stay around 75-83F. Humidity is always a little high like 60-70; is there any way to lower it especially since I will be flowering this week. Ok now for the pics:
1st: Showing the completely yellow and brown spotage on one of the cheese plant (any help diagnosing appreciated)
2nd:The strongest diesel ryder of the crop, hopefully Ill get at least a half o from her
3rd: one of my White Widow (very bushy)
4th:Overhead view of all of the plants.
5th: pic of the unknown sativa ( a beast!)
Thats about it for now I would have provided more pics but theres a limit.again all opinions are welcomed concern my sick cheese plant. Heres looking to a good Harvest!!

You're doing really good so far, I see you've probably been lurking on the forums for a bit before deciding to post! Welcome!

I'm not much help when it comes to identifying plant problems, but your girls seem to be doing fine.

i tried lookin around for anything dealing with brown spots and yellowing leaves...maybe this is the solution

Looking Great! What size homebox do you have? Passive intake?

Im about to start my Homebox XS grow, and i just ordered 5x Female Lowryder X AK-47 and there on their way :D

Happy tokin' :rastasmoke:

to deal with humidity, i set my AC to the "dry" setting (acts as a dehumidifier,) and i use a 45 Pint dehumidifier from best buy ($250 w/ a 4 year extended warranty) and this usually stays on the low setting (i set it on low and 60% humidity. it comes out a 39% right under the lights.)

also, HIDs usually make things dryer. i use flouros for veg cause its easier to keep the humidity up

Hey Dman, nice grow. How are those diesel ryder plants doin? im thinkin about buyin some seeds, are they worth it? sorry if this doesnt make sense i just smoked a blunt:jointsmile:

Nice grow you going on here bud, lookin good for a 600w :) give props to the least ammount of strench iv seen with plants spread at different hights by a 600w. More mature plants sure are lookin good, nice LST stragety

Hey if you're having humidity issues check this out, it's a great find!
