my mothers -under cfl's

my first posts were concerning high temps in my closet..got some inspiration and I'm continuing to correct the situation..i have four mothers, unlabled, but assured to one of each of the following: white rhino, skunk #1, kali mist, and northern lights...were clones i received 7.23.06...they came in a coco fiber medium as well as a inert fiber pot, and so i had to adapt (have only used rockwool in the past)..they are in five gallon containers of coco substrate..they are currently under 300+ watts of cfls, 1 85w 6500k 2 65 w 6500k, 3 27 watts 5500k, 3 19 watts 5000k..the plants cover an area 4x2..adequate circulation, but ventilation requires attention...the temps run b/t 80-93, depending on the time of the day...CO2 enrichment keeps the ppm @ a minimum of 500 to around 8-12 hours of 1000-1200 (i'm using yeast and sugar, home testing CO2 kit)...

i'm using basic chem nutes, dyna grow 7-9-5, superthrive, liquid karma, cal mag+, hydrozyme, at around 1/4 strength, 300-400 ppms/.4 EC - I'm increasing my nutes slowing by week, but the plants don't seem to mind the low ppms in fact, they have curled with 600+ ppm, but probably more to do with overwatering/heat also, 5.3-6.5 ph...watering every three or four days, although i watered a little more in the beginning... i prefer to hand water, just enjoy being around the plants, but i have remembered that every visit to the closet doesn't require a watering...

i've grown before, but never with any other purpose than just to grow..now i'm trying to make a little money, grow good dope to smoke, and to have an avenue to break from the daily grind of life, i forgot the hours of stress-fress thought that comes with being around plants (except for stressing over them, but thats ok, it's not work)...

each pair of pics are a before and after..the plants on 7.25..first day of transplant to 5 gallon pots and under 600w mh until 8.12(now in another location)..and then on 8.12 (moved the 600w and unlabled smaller clones to a different location)..

i would like these four to produce a decent quantity of clones in the near future, although my goal is to have harvest of 1 1/2 to 2 pounds per month (i have the space/rooms 4+ but i would like to be smart and methodical about it)..there are some clones sites available now, but i'm staying the course and letting them grow more...

i could use some advice on raising my mothers to maximize their potential..ie. how long should i wait until taking some clones (or the most efficient way to get to my harvest goals? how long should i expect the plants to heal themselves (i'm sure that's searchable) from a cutting? how best to avoid height issues at this point (the mothers are 14-20 inches at this point)? any other input, interest is appreciated, i will try to update once every week or so...I can answer questions directly about my setup (its basic, but hope to improve over the next few months) and how I would like it to be in the future, but i'm not qualified to give advice, only to take it.

The other two plants, C & D...7.25 and 8.12

the pics were taken today, in order, A-D

i'm ok with their progress...not a bushy as i would have expected or liked but they are coming along...under cfl's exclusively for the last week or so..the total light count is now

1 85w 64k
2 65w 64k
1 65w 27k
2 30w 27k
1 30w 64k
3 27w 55k
1 23w 55k

the larger lights are 1-3 inches aways from the tops, the others are positioned around the lower half the plants

it's still a closet grow, no true setup as of yet...door is open most of the day for ventilation, fan is working well, temps are 84-90 at the heat of the day..

browning on the tips, 1-2 millimeters worth..but not sure about the cause/cure..they are generally healthy so i have not tinkered with their nutes, schedule..watering every 3-4 days now, 480-600 ppms

Thats funny, you have 474 watts of floro power. I'm very interested in how this turns out.

maybe just poor genetics?

Hey Brothers Darkness. I am going to be growing with a similar light setup you are using... Could you give me a rough estimate on how much it costs you a month running 474w of flouros. Thanks in advance.
