Yeah more light is always better ,every little helps.. and as for nutes your doing great ,way better if you don't overdo it and just give the plant enough.. around about week 3 of flower you should give her some epsom salts .. i don't know the exact dosage ,but i figure that is where my plant started heading south.I know for next time ... but i'm letting you know for this time.. and if you start getting leaves yellowing from the bottom it's a nitrogen problem ,just feed her some nitrogen then.Your not overwatering or anything.. your doing a top job.. just look out for that 3 week epsom salt dose.. plants really burn through mg at this stage ..i have found to my cost..
