What strain, Seed bank, or bag seed (photo or auto)
-Age of plant
-Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF
-Vessels: Type and capacity of container (fabric, plastic, etc)
-PH and TDS of Water, Solution, runoff (if Applicable)
-PPM/TDS or EC of nutrient solution if applicable
-Method used to measure PH and TDS
-Indoor or Outdoor if indoor, size of grow space
-Light system List brand and wattage/spectrum
-Actual wattage draw of lights
-Current Light Schedule
-Temps; Day, Night
-Humidity; Day, Night
-Ventilation system; Yes, No, Size
-AC, Humidifier, De-humidifier,
-Co2; Yes, No
If growing Hydro some additional questions:
-DWC? RDWC? Autopots? Ebb and Flow? Other?
-Distance of liquid below net pot (DWC)
-Temperature of reservoir
-TDS of nutrient solution
-Amount of air to solution
We can help you out. Need more info. I’d say temps but need more info for these pros to chime in.

Original sour diesel auto 42 fast buds my plants are a week old im using ocean forest an happy frog mixed with some organic worm castings. Both are in gallon fabric bags manually testing ph so i would say no mre than 6.5 im indoors in a 48"X24"X72" grow tent i have a APQ1200 LED Grow Light: High Energy Efficiency with 2.6 umol/J, PPF is 260umol/s.Only consumes 400W just started using the ff trio plus the bush doctor cal mag today. An honestly my temps an humidity is everywhere when i do run my ,10"H x 4"D,fan the tent implodes an when i do open a vent the humidity get down to the 20 an 30s
Negative pressure in your tent makes the walls suck in when the inline fan is on if that’s what you mean. That’s ok. If the walls of the tent come out your exhaust tube is on the wrong side of the exhaust fan. Also Intake air can come in at the bottom of the tent and exhausting out the top. If your in early veg your humidity needs to be higher. 70% ish for veg.
What’s actual temp in the tent and where’s the probe located?
Thats my set up temp Guage is hanging out the left vent or dho7ld it be on the floor?
I usually keep my probe at canopy level and move up as they grow. So for you just above the pot. What’s your temp set at? Home heat will lower humidity so you’ll have to get a dehumidifier. Open a vent at the bottom of the tent and let the fan suck the air out the top to cool things down. They’re young tho. Keep temps below 80 and humidity above 60 and below 85. Again that vpd chart I posted is helpful.
So opening vents an letting light out is ok?

Look at the plants the still look very young, maybe too much water. Did you transplant them or grow them directly in smart pot. Alsontry watering at least 3 inches from the main stem to promote lateral growth. Of roots. When you say curling up do you mean tips or is leaf folding like a taco? If tips are curing down could be a sign of over or under watering.

Letting light out is okay. You don’t want to let light in during lights out on photoperiods

You said you’re in FFOF and FFHF soils and at 2 weeks of age? You shouldn’t need any nutes yet, both soils will hold for up to 6 weeks without using nutes. At their age, you shoukd be fine with pH’ed (6.2-.8) water.
And btw, excuse my manners, welcome aboard!!!
Back to it…
Your humidity is also really low. For their size, i suggest getting a couple of empty 1 or 2 liter bottles, cutting the bottoms off, and spraying the inside with some distilled or RO water. Place them over the youngsters for a few days, keeping it misted a couple timea a day.
This acts as a humidity dome, and with their size, it can be very easy to overwater the soil. A humidity dome for the next few days or maybe a week can really help. Just watch for droplets to form on the leaf tips as they can become dry and crispy when the dome is removed.
For feeding, be sure to follow the FF schedule, and use all three of the trio together when needed. A few weeks into veg, and once or twice later in the grow, the schedule calls for a “SledgeHammer Flush”. This is pretty important with the FF lineup. Salts buildup in the root zone and can eventually cause issues. The flushing helps keep this from happening so your roots keep on sucking up the good stuff.
Hope some of this helps! Good luck and happy growing!!!
