need some help (pics)

#1 is the only one left for the bagseed I germed on 1/25. so its 23days.
#2 #3 #4 are from a friend said to be skunk #1. so they are 14days.
do these seem little for there age? how do they look?

lights: 1000w 24/7 30" away from plants
temp:73-78
humidity 35%-39%
water:
ph: 5.5-6.0
5 gallons 1/2 reverse osmosis 1/2 tap water
rockwool formula 1 A 5 tsp 5-0-4
rockwool formula 1 B 5 tsp 1-5-5
northern lights bloom enhancer 1/2 tsp
watering twice a day. about 5min enough to wet with run off.


the hydro-guy suggested the bloom enhancer after I described my plants to him. he said sounds like I have major ph swing and need a little fertilizer.

anybody have any tip? seems like mine are growing much slower than others I have seen in the journals. also I can ph the water to 5.5 then test the run off and its 6-6.5. is this normal? do I need to flush the plants or what?

#1 #1 #2
#1 #3 #2
#3 all 4

in pic one it looks like its over watered and has a signs of some kind of deficiencie starting.

yea the over watering is from me rigging the drip system. it took a few times. its my first grow so I am not for sure how often I should be watering. I have done alot of reading here at riu. (maybe not enough) I am still unclear. I will cut back.

any suggestion on the nutes. where talking only 14day old.

thanks for the reply.
