appreciate guys i got 5 plants and all of them have it on them a little bit on the bottom leaves and i had no clue why. If i where goin to add nutes about how old should i let the plants be so it doesnt shock or burn the roots up?
I am by no means an expert, but it would depend on what type of soil you are using. I use Fox Farms Ocean Forest, which has a good nutrient supply in it, and I usually wait till about the 3rd or 4th week and start adding nutes every other watering at about 1/2 strength. If you start noticing your bottom leaves turning slightly yellow then you should go ahead and start. After about the 5th week I bump it up to full strength. Once you get a few grows under your belt you get a better feeling for this sort of thing.
Hope this helps!

I'll take all the help i can get right now i got 3 100 watt cfl's 1 6500k and 2 5000k and a floru grow light i know i need alot more lights well really i need alot of stuff but really i just started off with miracle grow moisture control potting soil i got 2 bagseed plants that are about 2 months old and 3 chrystal sprouts and another seed a just got from a bag of smokin stuff...but 1 of the chrystal sprouts just stopped growing shortly after it broke the surface...i would give pictures but it says they're to big and i need to re size them and not really sure how to do that...

Yes yellow on the leaves like that can mean too much water, but be sure you also have the lights far enough away so its not the light burning the leaves like that. i would keep the light 12-18" away.

Turn the resolution quality down on your camera. That'll help. ANYWAYS.....I have grown with CFL's forever....and it's really hard to achieve LIGHT BURN with them. They have to be like within an inch and decent size water droplets. CFL photons do not dispurse in a linear pattern like HPS lights do. Making it very difficult to focus the light.
If it's happening to all of them, maybe over watering, or lack of ferts, which shouldn;'t happen at this stage, unless your dirt is severly lacking.

IF your CFL's are actually 100w, the you have enough light. HOWEVER> it is my feeling that you have 100W equivelent.
Which means your cfl's are 23-27 Actual watts. Go check it out on the bulb.
Pay no attention to the guy above sayin keep them 12-18 inches away. He obviously didn;t read your light setup. You would likely only do that with HPS/HID lighting.
You wanna keep those lights 1-3 inches away at all stages if you decided to flower with them. You'll need 2700k for that.

yea they're 27 0r 26 actual watts with the equivalent to a 100 watt...do you know the difference between the cfl's i got and a 125 watt cfl from the hydro store? pic are on the way hopefully
appreciate it sgt. sly anymore advice will be much appreciated

If it's the 125 actual watt then the difference would likely be lumen output and maybe they designed the spectrum to be more ideal for growing.
However, here's something cool i learned. Remember what i said about CFL's photons diffusial pattern? Well same goes for the 125W. It's a nice light , problem is:
1. One physical light makes coverage difficult.
2. Cost to replace.
3. Lumen's per watt. 42-65 Actual watt CFL's give you the MOST Lumens per Watt Ratio. Means you get a little more out of your power costs.
Plus with MORE of these great smaller bulbs you can obtain greater coverage.
You're likely to get much better results from 125 watts broken up over multiple bulbs than in just one.
The minimum For good CFL grow, is 3000 lumens per sq.ft.
1-42W 2700 or 6500K CFL = 2600-2800 lumens.
You can use this as a rough guide and put 1 bulb per sq.foot you want to cover. Get good reflectors or make em, it helps HUGE. Some use pop cans, slice em open long way and open up like barn doors, light goes inside. Genius.

i had a couple of idea's for my setup i just dont know which one would yeild the best... havin 2 actual 125 watt cfl at the top and 2 cfl's like i got now on each side or just go and get a bunch of cfl's like i got now and put 10 on top and 6 on each side with homemade reflectors like you were talking about...

i water them usually every 2 days if the soil is sarting to dry out at the top...someone told me to think of it as a cactus instead of watering a little every day water good every 2-3 days...

However you do it, i would go with the cheapest option. Ultimately i'd get a 400-600 HPS.
Design your setup at the top with a pulley and string system, so you can easily raise and lower your lights. Just keep em cfl's CLOSE i can't stress that enough, if you don't your nugs will end up popcorn like and airy.

Ya but you want it to be like dry like half way down. It's ok and very good for the soil to dry out almost completely. MJ will bounce back from a drought much faster than over watering. PLUS it's easy to get a feel, just let em go without water till you see the first sign of wilting, then totally saturate the soil.....it'll be perky in an hour.

With an hps though ventilation and cost is an issue but ultimately thats the goal but cfl's are more cost friendly right now...i already got my lights on a pully system to make things easier... do you know if its better to just have all 1 color light for the cycle they're in or do you think a good ratio like 2-1 or 3-1 would work better? do you think its to early to put the bagseed plant on an 18/6 or should i let em get taller they're about 8 inch and about 2 months old and my chrystal is about a month and a week and its about 4-5 inch

Ok that makes sense...like i said i'm new at this and like everything i do in my life i like to do it how its supposed to be done and really i just love mj to much for her not to grow to its full potential...thats abuse haha you're helping out alot sgt. good lookin out

It's never too early for 18/6 light cycle.
I personally use BOTH 2700 and 6500k spectrums, through out the whole grow. If you cannot do that., i suggest 2700 for flower, and 6500 for veg.
2 months old? Which one? I didn't see any like that in your pics?
