Ak47 X Lowryder2-Running into a problem, please help.

This is AK47 X Lowryder2 feminized. I am growing indoors. I am using CFL's; 1 45W 6700k, 1 26W 6500k, 1 40W 2700k, and 1 40W 3000k. This plant is about 2 and a half weeks in. I have not used nutrients yet. I am watering about every other day. I make sure not to overwater since that happened with one of my outdoor grows. The water is moutain water (I live on a moutain in Costa Rica). The soil came from an area where banana trees and coffee plants are abundant. Based on this information can anyone help?

Your water and soil sound great!!! Cfls should more than cover it, you got a HPS for 12/12? Gonna add nutes?(nute burn) The plants look great so far! Just make sure not to over water and you should be fine! +rep!

Nuteburn? Could have been fertilizer in that soil you use. I understand Ryders are very sensitive to nutes.

maybe nutrient lock-out due too the ph of the soil or water??

Flush soil?
Looks like nute burn to me also.

Hey, I wanted to get back with those of you who ended up replying and offering help. Turkish420 no I do not have HPS for 12/12, I've kept lights on 24hrs, if anything I was going to put more CFLs. Thanks alot, it turns out that my ph was a little high. I lowered my ph and waited to see how things went and it took a turn for the better. The burning on the leaves does not seem to be spreading. Once I noticed everything was good I fed it for the first time on Wednesday and it looks like it's on track. What do you think? Again thank you for your help everyone. Here are some photos of the progress.
