Strain : Green crack auto freebie unknown genetics, 3 gal fabric pots

Day 12

Medium : Mother Earth 70/30 coco perlite

Light : Mars hydro fc3000 (300w) @24” and 50% on dimmer (leaf temp ~64F)

Temps : 73-75F and ~ 65RH

up until day 7 was watering with roughly 200ppm but not until runoff

Following coco for cannabis schedule using flora trio only + calmag

Starting since day 7 I have been watering every other day until runoff following this schedule which is about 500ppm it consist of
-3ml/g calmag
-2.25ml/g micro
-2.25ml/g gro
-.6ml/g bloom

Ph 6.0-6.2 & starting tap water ppm ~160ppm (.5 scale)

Hopefully I didn’t leave out any needed information any helps appreciated

does a 64f leaf temp seem ok to you?

Definitely not but I’m struggling enough keeping the ambient temperature of my tent in the mid 70s right now. I didn’t think that would be the direct cause of the issue I’m seeing but I don’t know so that’s why I’m asking

Your going to need a space heater to keep it warm. Get the lights on temps up to 80f

i'll second this and add, 82F would be better. you need that LST up at high 70s for proper transpiration. not that it really matters right now because you're in early veg but without proper temperature and RH your plant is gonna struggle to get to a size it can perform in any reasonably economical timeframe. time is money, and electricity is gettin expensive these days.

Looks like ultimately I will want to buy a oil radiator heater on some sort of controller like an ink bird however I already went way over my initial budget so I'm going to have to wait a few weeks unfortunately.

For the time being I'm going to see how raising my light from 24" @50% to 30" at 100% will effect temps. at this height it should be roughly 330 ppfd. Is this reasonable or would you go higher/lower?
