i think thats polyploid or something like that, just a filthy mutant, ive heard they can yield alot more sometimes never had it myself someone will know.. could be ph issues on top of that just the deformed leaves and bark in the soil it looked like that but its all guesswork anyway.
whats your runoff ph? if you have a meter
looks like youll need a lot more light to flower, just something to think of itll be ok for veg probably but youll most likely end up with airy buds. optimal numbers i remember were 3000lumens per square foot for veg and 5000 for flower or as close as you can to get good dense results.
hid lights are good for this as theyre much more efficient but if you cant do that then id just add more cfl until heat becomes an issue. some t5s (tube flouros) would be a good inbetween
