First Grow under CFL, 5 weeks

This is my first grow, and I've chosen to use CFL lights in my closet. I started out with 4 seeds, all 4 germinated and sprouted, 1 didn't make it. I'm left with the 3 in the pictures. I'm currently using DNF Grow A-B 1-2 times a week at 1/2 recommended mixture, water roughly every 3-4 days.

All 3 plants have grow differently, guessing must all be different strains? The one plant is like a little apple tree, the other one is just growing tall now, and the third got munched on by my cat (i left them out, got high, forgot, cat loves weed leaves) on one half of it, but it seems to have been recovering.

My questions are, and any answers or help would be GREATLY appreciated, why are a few of those leaves almost completely yellow, do those tips look like heat burn or nute burn, and can anyone guesstimate about the actual strains they might look like?

One last thing, I'm using 3-42 watt 6500K CFL's, 1 OttoBrite 23 watt 6500K CFL, and 2-40 watt 2700K CFL (for a mixture of wavelengths, been reading is a good thing). They are on an 18/6 schedule, are rotated throughout the day, and sprayed multiple times with plain water on the foliage.

Thanks in advance for any replies.:leaf::leaf::leaf:

If you got the seeds from the same bag they are probably the same strain but different phenos so they have slightly different traits among them. Also what are your temperatures? Cause that yellowing you have going on there could be from many things. My thoughts are lack of humidity from high temps. Another thing that causes yellowing is lack of Nitrogen but since you are vegging and using veg nutes 2 times a week I doubt that is the reason.

If you can just get back to us with your humidity and your temperatues. Also do you PH your water? Other than that the plants look healthy, expecially the one(s) you toppped.

Also I wouldn't feed that often. I looked over at the pictures and it seems like that is nute burn but I could be wrong. The plant will let you know if it needs nutes. I would just give veg nutes at half or quarter strength every other watering or once a week.

Also how far are your lights from your plants? cause that could be heat burn but the leave itself tends to curl a little also, not just scorch the tip

Hey! Thanks so much for the response. Honestly, ive read tons of these threads, and it's cool having my own plants involved now!

I dont have a hygrometer (lost the one i had, but the soil gets dry very fast, so im guessing its not too humid in there (I thought of that in the first week, but got some really good medicinal stuff, and it kinda made me forget lol). I was thinking of putting in a bowl of water or something to try and raise the humidity a bit. It's a pretty confined space, but i cant take a picture cuz i only have the webcam camera atm, but i keep the lights anywhere from 1 inch to 3 inches away.

One thing I noticed with these plants though, it's all 3 stems are super thinck. They have never stretched and are really densely packed (hard to tell with the pics). They were never spindly. I believe the temp is around 80. One last thing, since the fan is so close, could the curling leaves be because of the wind too directly on them?

What I like to do for getting humidity up is twisting a rag up and sticking it in a plastic party cup and filling it with water and putting a few of those in the box and in front of my fans. Also plants usually grow faster with good temps/humidity and less light rather than tons of lights and ridiculous temps and low humidity. So try taking the 2700 lights out for veg right now and see if they do better. Lower temps will also increase humidity.
