for a long time i had a spare pot potted up sat in the corner of the room,just to lift each day before checking on the girls.

Day 12
Got my ventilation system setup today and am ready to turn on when needed. IMO, massive airflow at this seedling stage is probably not necessary. There has to be plenty of co2 for these tiny seedlings in a 4x4x7 tent and all it's vent holes. Maybe I won't need any circulation if I just sing to these girls for 30hrs/day!!!

Day 14

Received my cool-mist humidifier today and added to grow tent. This should allow me to maintain a decent humidity level of 45% - 65%. Still need to get the temperature between 72deg - 85deg F. Cooler at night seems OK based on what I've read.

Submitted a query to the cannabis 911 forum (aka: Autoflower Infirmary for sick plants) See Below:

Being it is my first grow, I am a bit paranoid with anything that looks odd. I am in day 13.
My concern it this. One plant is 2.5in tall with a leaf span of about 1 inch and the other is 2.5in tall with a 1in leaf span. They were germinated at the same time and have been twins with respect to their environmental conditions.

I am concerned with their height or scrawniness. Is This normal or is it typical of a plant that has not had enough light. Early on I was using CFL lights for a few days at 18in(too far I know!), before moving them under my LED COB lights. I was mainly using 1 400W LED COB light at about 18 inches from the tops of the plants(19/5 sched, 100% Veg), with a second light(same as first) turning on for a shorter period of time(50% 8/16 sched, 50%Veg, 50%Bloom)
I gave them their first real seedling nutrients a couple of days ago @ 75% of the recommended seedling dose(General Hydro - Flora - DTW)
I have been struggling to keep the temperature between 75-85degF and the humidity at 70%. I delibertely was keeping the humidity down so that the soil could dry out some from what I believe to be a "too much water" situation.

I asume the size difference is a difference in the 2 strains, but I think I misplaced the labels for each strain.

Bottom line: the two questions are: Does the light given seem ok? Did it get over-fed? Only gave it nutes once.

Or should I get a couple more seeds started to be on the safe side?

Possible Solution...

General Hydroponics Flora Series is designed around using tap water with PPM under 250. Distilled water will be 0 PPM. So at a minimum you need to add Calcium and Magnesium every time you water including for germination. You will still be missing out on all of the other trace minerals that would be in the tap water. Why are you using distilled? If your tap water PPMs are to high just blend the tap water with distilled to get it under 200 PPMs. If you do not have a TDS meter get one.

The cob leds should be at 30"



OK then. So I definitely am getting off to a rocky start.

Actions:
o Ordered TDS Meter
o Raised LED's to 30"
o Diluted distilled water/nutrient solution 50/50 with tap water
o added additional nutrients + calMag
o re-calibrated pH to 6.0
o will water tomorrow

Thanks @Mañ'O'Green for your insight. The distilled water is likely the main culprit. Not exactly sure where or why I decided on distilled water. Information overload, I guess!

Notes:
From Reading:

Things that could cause stunted growth:

o Inappropriate spectrum of light
early on the first light they had after poping out if the rockwool was window light coupled with a double CFL at 12 -15in (I know too far)

o Overwatering
after adding the rockwool cubes into a small pot with coir/perlite, I did water them...perhaps a bit too much.
At this point I allowed the humidity to stay low so as to adsorb that moisture

o Improper pH
pH had been measured at 6.0

o Low Nutrient Strength
since early seedlings do not need much for nutrients I hadn't given any till day 10 or 11(.75% of recommended)
