They look fine to me.. plants that are at their happiest have leaves pointing up, but it is fine a little wilt. Are you watering until it runs out the bottom and letting them dry well before watering them again?
Do you have spots on your leaves? Do you wish i would quit asking you questions?

I suspect the soil you are using is the problem with the wilting leaves. It looks like it doesn't aerate well. A little trick to help you get over the hump is to aerate your water with a fish tank air pump and stone for 12hrs and then adjust pH again. This will saturate the water with oxygen that the roots need to thrive.

Anytime you are starting from seed, you have to be very careful what soil you use and how dense it is, how much nutrient is in it. Its not good to use a prenuted soil as that can be too strong for young tender roots. Once the roots system is established (around 2-3wks) the plants can handle much more variance to the soil conditions.

The lighter color on new growth is not too unusual. But it could be a sign that something is just a little "off". the usual suspect for problems is the pH being off some. It could also be your soil. sometimes with commercial soil, you can get chemical binding that locks up a certain nutrient element where the plant cant absorb it. What kind of soil do you use?

Do you put anything in the soil to break it up so that it aerates better. I use large pebble pearlite to break up my soil, at about 25% or 3 parts medium to 1 part pearlite. This prevents the medium from compacting too much when watered.

The FFOF is good medium but I have heard of people having issues with salt buildup in it. It also seems to have enough material to break it up that compaction shouldn't be an issue for the larger plants. I would just watch the plants right now. If the new growth straightens out and greens up as it grows then it may just be a trait of that strain.

However, if they continue to look "off" then I would suggest you do a soil pH test. You may have to flush the medium if they get worse, but I would just watch for now.
If you do end up doing a pH test, you will need to get distilled water and pour through the medium slowly and then catch the runoff in a clean pan so that you can check the pH. Don't use regular water as it will have elements in it that can throw off the pH. The distilled water has nothing in it and will more easily take on the pH of the soil and give you a more accurate reading.

At 70f, if I am reading your thermometer correctly, and 40% rh, you are well below normal temps and your low rh are affecting transpiration. What seems like a normal watering routine may actually be perceived by the plant as overwatering, considering it isnt able to transpire properly.

Feed less in a feeding, no runoff.. Or, the better idea, get your temps up to 78f and your humidity closer to 70% and watch your plants explode.

The vpd for cannabis necessitates roughly 60-75% RH at 78f for optimal growth.

Hope that helps

agree! my growing guide on my fluence led says 80 to 85 degrees is ideal and also likes 55 to 65% r.h. as ideal, as well. i think the temp will vary from strain to strain. where the r. h. is more constant.

70f is a little on the cool side for young clones or seedlings. I try to keep mine around 80f.
