PPP NL journal updated !!!!

hi guys....as you can see ive posted an update...this update is for the N L's...ill post and afghani update proboly tommorrow. Ok first what we have is the youngest N L is it exactly 2 weeks old its doing very great ...nice and healthy looking to me ( altho u guys be the judge ) and is catching right up to the other NL ....now secondly we have the oldest nl ( second pic ) and it also seems to be doing very well...both saying very nice and compact with the early sets of leaves being very close to each other. Ive ran into my first bump in the road ( third pic ) ive noticed some slight browning on the very first set of ridged leafs ( the set after the tiny petals ) anyway ive noticed some browning...it cant be burn from fert or light b.c the light is close but not to where it can burn....not only that but is a floresent cool white setup, it cant be the burn from ferts b.c i havent used any yet b.c i am now at the 2 week marker i havent needed any yet, i am quiet unsure what it could be from so maybe your guess is better than mine....thanks for all the imput...
happy growing
