Dutch Passion: Dutch Haze feminized

Hello my friends! well i think i have a lil problem here as these ladies are borned in soil pot at 31/aug. now.. about 1 month old and i think they are to small for their age!? what you think?
is this normal for a dutch haze (allmost sativa) to look like after 29 days from germination??
i water them every 3rd day with HESI TNT complex fertilizer about 60-70% of normal dosage.
i dont have a soil ph meter, but i have a water ph meter, and i correct the ph in the watering with fertilizer to be about 6.0

well i think they are growing a lil slow what u think? the heigh of the plants now is about 20cm.
Thank you.

PS: Lefto photo is from today(29/sept) and second at 20/sept.

what kinda lights you useing , and wattage

u think they dont get enough light huh? i think that to..but idk.. can just the light be responsible for this height? i mean its about a month old! anyway i started for veg with just 4 cfl lamps 1060lumens each about 30cm away from the plants. but i have a sylvania 600w hps 90.000 lumens i wanted to use it for flowering because i havent completely finished my grow room to get rid of the heat from this HPS lamp.

ps: you can see the type of lamp i use in the second photo down-left.********

ello m8 i started mine not so long ago white widow n pinaplechunk and the WW are about 18 inches and the chunk is the same age as urs and she is feminised and she is about a 14 inches so i wud say man that they r small for the time frame but i aint grew sativa's before so not sure of there traits but i wud think straight away that its a lack of light i use a 600 watt hps in soil and they explode wiv growth in 4 weeks, ope u suss it, but if u av a 600 watter then u shud be using it i used mine imedietly after sprouting, let them get there first set of leaves then strait in the tent under the 600 watter andlike a sed they av expoded in growth
