Plants are starting to turn yellow, leaves are starting to curl. Not sure what on earth is going on. They were looking good just yesterday. Woke up to find them like the picture shows. Also included In pictures is my set up. I've had nothing but trouble with growing plants in this box. Keep my p.h. between 5.5 an 6.5. Use the recommended nutes for that age. Just don't understand why I'm having so much trouble. I've grown in soil but I'm trying coco coir this go around. I thought I was following everything step by step with it.

Are you using nutrients made specifically for coco? If not coco needs a little more calmag than soil. But I don't use anything but PH water the first week after emergence and then start at 1/4 the recommended strength. work up from there. Your plants get energy from the sun and oxygen from the water. Nutrients are needed but not in excessive amounts.
Your two plants look pretty decent_ the little round leaves at the bottom should turn yellow as the seedling matures. They are the first "food" your youngster gets.
Get ready though...it won't be long until they start "raiding the fridge"!
If the "real" leaves start to curl more then its probably a humidity issue_ you don't have them under a dome to keep it humid so those young leaves can start to dry out.
At this stage they don't have much of a root system so they get some of the water they need from the air as well_humdity should be above 50%. I think that might be your problem. try misting them with a light spray with water only_ no nutrients on the leaves! They are tender. Then spray a little around the stem to moisten the top layer of soil. You can make a dome from plastic wrap over some kind of support, or a clear plastic container turned upside down. Just keep it warm and moist inside and make sure there us enough head room so they don't grow into the top of the dome. If they start to stretch too much, then lower your lights and keep an eye on them.

Yup, I agree. Those bulbs will need to be pretty close if you set up a humidity dome...and you'll need a good deal more light to get much out of them in the near future unless you get some more light. For me light ranks first, water second, environment third and nutriments 4th. Genetics and all play a major part too of course.Current grow_ coco based medium, Fluence LED lights, AIT, 5 gallon planters,

Nastyyeti yeah, agree with all the above. Nebula says the light is like food and the nutes are more like supplements. If you don't give them good strong right kind of light, you won't get good strong right kind of results!!!Anyone can grow schwag.

Okay guys I had two bigger cfls that are 60watt laying around the house. Until I can get the funds up to buy a better light system. Also I used my microwave plastic dome as I couldn't make it to the store to buy seran wrap. Could this possibly get me buy for a couple weeks till I can afford a better light?Comment

I love the way you have the dome rigged, because it's open on the bottom to allow for air flow.
I just looked this up on GWE: growing with CFLs:
It says that CFLs are not the best for huge grows, which you aren't doing right now. Here's what else it says:
1.) Start with about 150W worth of CFLs, which is enough light for one small plant
Total of 150W Per Plant to Start
Example Setup: 2 x 40W 'daylight' CFLs + 2 x 42W 'soft white' CFLs
2.) Smaller bulbs = better results
Because the penetration of CFLs is poor, many many smaller CFLs is more effective than a few big CFLs because they can be spread in an array around the plant.
For example, 4 x 40W CFLs (at 160 watts total) will usually get bigger yields than a cannabis plant grown under 1 x 200W CFL, even though the smaller bulbs use less electricity in total.
For tiny plants in a small setup like a space bucket you want 20-30W CFLs. If you plan to grow your plant up to a foot tall, you may want to use 40W CFLs and bigger since the smaller ones won't have enough penetration to reach the bottom of your plant. 40W-sized CFLs are a great combination of power and penetration when it comes to growing cannabis with CFLs.
So, Nasty, it looks like it would be better to go back to the smaller wattage and just add more of em.
