3 plants, 20 days. Look ok ?

Hi there rollitup people,

thought I`d share my three Spanish ladies grown from seed, sprouted 01.11. So 20 days today:
Dinafem - Moby Dick
Seedsman - White Widow
Seedsman - Lemonchello Haze

Grown in coco /food : Canna Coco A+B only / under 250W HPS

What do you think about their growth considering their age?

Looking good man. I would veg 7 more days then flip seeing how you don't have a ton of light . dont over veg them

My ballast is set on 250W now, once I flip will turn to 400W

Nice pots look good

Gotta love those air pots.
Are you feeding daily? Your coco looks dry and I see some problems on some of the leaves.....what pH are you using?

Im watering by hand once a day or if the pot feels very heavy, I dont.
Probably seems dry above, cause HPS emitting heat.
My PH pen broke 2 weeks ago, so waiting for new one. Right now dosing PH minus by memory only ...I know not good.
PH minus I use : HNO3 38% from my local Hydro shop

So far so good I think.
Added some cal / mag to the feeding and raised Coco A+B to 2.5ml / 1L
Day 26 of veg today.
I think 1 week more and then it`s time to flower ?
