I've been having a situation with 1 of 2 plants currently in my micro grow box. Both are the same age and strain.
The problem as can be seen in the picture is a curling of some leaves, It's happened 2 weeks before and it went away as soon as I transplanted from a 16 oz cup to a 2 liter pot, 10 days later it happened again, and I'm not sure if it was the transplant that helped or the watering that came with it.
Currently growing in SOIL:
How long has this problem been going on? It started 1 day ago, although it happened 2 weeks ago and lasted 3 days until I transplanted from 16 oz cup to 2 liter pots.
What STRAIN are you growing? World of Seeds Colombian Gold Feminized.
What was the establishing technique? (seed or clone?) Seed.
What is the age of your plants? 28 days old since breaking soil.
How long have they been in the soil mixture they are in now? Since the beginning.
Were they in the same mixture when they were seedlings/smaller plant? If not, what mixture were they in before? Yes same mixture.
How Tall are the plants? 8 cm, just over 3 inches.
What PHASE (seedling, vegetative or flower) are the plants in? Vegetative stage, dropped the cotyledons 4 days ago.
What Technique are you using? (SOG, SCROG etc) I only have topped once around day 16, topped the 5th pair of leaves as it was appearing.
What size pots are you using? (Include how many subjects to pot) I started in 2 oz. pots, 9 days after breaking soil transplanted to 16 oz cup and 9 days later I transplanted again to their current 2 liter pots.
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) Biobizz Allmix.
What brand Nutrient's are you using? So far none, just plain water.
What is the TDS/EC/PPM of your nutrients used? I’m using tap water which is naturally soft, 20 ppm (or 0,04 EC).
What is the pH of the "RUN-OFF"? Haven’t measure pH, mainly because the water is very good here.
How often are you testing pH/ppm/EC/TDS? pH, never. EC every time I water.
How often are you watering? I water every 3 to 8 days depending on how most I notice the soil.
What size bulb are you using? I’m using 6* 10 watt led bulbs.

What is the current Air Flow? (cfm etc.) 17 CFM
Tell us about your ventilation, intake exhaust and when its running and not running ? Passive intake with exhaust always on.
Is the fan blowing directly at plants? No fan blowing at the plants.
Is the grow substrate constantly wet or moist? No.
Is your water HARD or SOFT? soft
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? Tap water.
If using tap water, what is the ppm/EC/TDS of the water right out of the tap?(Only if you have a tds pen) 0.04 EC or 20 ppm
If using RO,Distilled,mineral water, what is the ppm/EC/TDS without any additives?(Only if you have a tds pen)
Are you using water from a water softener? no
Has plant been recently pruned, cloned or pinched? No.
Have any pest chemicals been used? If so what and when? None whatsoever
