what u were seeing was the good ol fashioned MG burn. it happens when U plant directly into MG soil without giving your plants time to mature first...n00b mistake, nothing serious...next time germinate in rockwool or a jiffy cube first and allowed the plants to get about 2 weeks old and then transplant into the MG.
For now just flush the plants asap and make sure U get a good amount of ferts out of the soil (you will know bcuz the runoff water should start off orangeish-brown then the more water U flush thru the soil the clearer the runoff water will get..when its just a little yellow it should be alright.)
then you can add ferts
as needed.
You should be fine if you flower now
Keep those CFL's no closer than 4-6 Inches.
Make sure U dont give them too much waer, they're looking kinda overwatered, and when u start feeding start off at 1/4 the recommended dosage and work ur way up. Its always better to underfeed/underwater than to overfeed/overwater...simply bcuz its easier to correct.
besides that ur doing pretty well. keep it up
