Are my girls cold ? Or shy?

[Frenjamin Banklin]

Started a journal of sorts but wanted to affirm some concerns. New grower fist grow.

DP glue berry tallest at 7 weeks. 19" tall by almost 30" around growing an inch a day still.

Mephisto Sour hound and RQS diesel one week older at 8 but both smaller. 14 " tall and maybe 20" around. Still growing about an inch a day.
All under 3000/4000 cobs at 50w per plant until two days ago bumped to 75w per plant. Started at 30 and they have been growing to light with no signs of burn or light stress or burn. I think.
Res is 8 gallons with 6 water and between 65-68 decgrees F. Running hydro guard and other than nutrients stains roots look good. Been steady at 5.9 ph without movement entire run.
Nutrients are Megacrop, silica, and Sweet candy along with cal/mag. Started to add koolbloom this week in small amounts. Pushing all plants to tip burn with the Nitrogen. Between 3.5-4.5 total EC depending on plant. Big girl is drinking a lot but my EC and PH are lock step so u feel lucky so far.
Room temps are 70F with 50% RH.

Lights schedule was 24/0 first 4 weeks. 18/6 next 4 and just dropped to 16/8 hoping to push them to pop. They are showing pistols and Bud sites seem to be popping but I'm just not see those white button preflowers.


So I know they're behind but are all good genetics. My thoughts were large reservoir, cool res and room temps have these girls moving slowly. I know they all show a little cal/mag leaf variegation but I'm chasing that trying to not go to far to fast and get lockout.

So do I just let them keep going ? I'm in no hurry for now.

Thanks, any feed back is welcome

A bit cold me thinks. It will slow them down a bit. They will still go but may make grow longer. I would leave lights at 24/0 or 20//4.

They all look good but should be showing more pistols.Try and get temps up closer to 78 to 80 and keep giving cal/mag maybe this will help.

..yeah, 70 is on the cool side,.. amazing what even 5 degrees difference can make! Overall slowing, but some nutes, like micro's and P are rally affected by lower temps for uptake and transport,... warm it up in there if you can!
