Week 2 Ak48

Week 2 of my AK48 from Nirvana. Just started adding nutes this week, and also added a cool mist humidifier.

The lighting that I'm using while vegging - 6 6500k cfls 4 75 watt and 2 60 watt, once I start to flower I'll switch to my 400 watt hps. So far I'm just winging the nutes as I don't have a ppm meter so I'm just playing it a little light with them. PH has been staying in the low 6s or high 5s. I can't really tell as the test strips are a little lacking in definition. any input would be appreciated

i use the liquid tester i keep it between red and green, i like orange
