Indoor Grow journal BB blue cheese + Critical mass

[dkauto]

My set up atm
Homemade grow room like 4 sq meters
360 cfm fan + filter (out)
2 x ventilator
1x 195 cfm intake fan to pull fresh air from outside
1x 600 HPS
1x 250 HPS
temps 28 c -26 c daytime
19-21 c when lights are off
when i water its ph 5.8-6.0 ( i got a bad ph meter)
as for nutes i use vitalink series
there are 8 x critical mass (from big buddha seeds)
and 6x Blue cheese
They are 15 days old atm and the first white hairs just shown on 3 of the plants(isnt that a bit early?), this is my first indoor grow, and that is kinda also why i made this journal, so if something comes up i can mabye get some help from someone who are more experienced.
so far i have had some problems as my room got to hot and my plants got a little heat stressed but they seem fine now, i will post some pic so you can see the progress so far. i am doing some low stress training since i sence that space will be a problem having that many plants in there.
and i did top 2 of the plants by mistake, when i was LSTing the plants i was being to rough 2 times and the top broke but they do not seem mind they look just fine

Subbed up man, very keen to see how your blue cheese does.
I have some blue cheese seeds but so far not got around to germing them.
Currently in the middle of a NLxBB grow, along with a Sweet Skunk grow.

I did my first LST with the NLxBB and its going ok, I found holes in the sides of the your pot work well with just string or twine.
I gave up on the pipe cleaner method as my plant kept pulling them out of the soil.
