Please help! Slow growth, curling leaves, tried everything

Hey, guys, can you please help me with my problem?

I'm growing from the seed for the first time, I've always started with clones before. I successfully germinated, put them under CFL for a while, now they're under 600W MH lamp.

Setup
- 9 Bubba's Gift plants from Humboldt Seeds
- 110x110x160 growbox
- 600W MH lamp (Superplant)
- Coco

Fertilizers
- I put just a small amount of Jungle in da Box fertilizers + Supervit.
- pH 5.8

Now the problem:
Symptomps:
- Slow growth. I literally didn't see any change for a past weeek.
- Leaves curling as you can see on my photos
- Branches are very close to each other but that may be a problem of the strain

Dates:
- Seeds germinated on 7.10.
- I put seedlings under 600W on 16.10.
^ this means the plants are almost month old. Are they supposed to be this small?

Probable causes / What I tried
- At first I thought the plants are freezing. The MH lamp doesn't produce much heat (it's in cooltube) and I use a humidifier that produces cool mist. Cool mist is the first thing I thought is the problem. I stopped using the humidifier for like a day or two, but it didn't help and humidity dropped to 30 % so I turned it back on. The temperature is 20.5 - 24 °C. Humidity around 50 %.
- Because of the cold problem, I closed a window a lil' bit. Not entirely, there's still a gap. But, I thought that maybe plants are not getting enough air. However, opening window didn't help and I used this technique before with much bigger plants with no problem.
- After reading some articles, I suspected my plants are suffering with bud rot. However, roots are not brown or slimy and there's no smell.
- I'm 90 % sure it's not overwattered or underwattered. I water them every day with little bit of water and fertilizers and next day, they're almost completely dry.

-. Both guys before me are right., fix the problem and many deficiencies will go away...
Overwatering & underwatering
High humidity
Uneven moisture levels in the soil or growing medium
Too-high levels of N-P-K nutrients
PH is too high or low

Also when u transplant make sure to add some perlite for drainage and to keep good oxigen level at root zone. GL

When I water my plants, next day they're almost dry so I don't think they're overwatered. I tried to add more water, but that seemed to be too much, because they were still pretty wet next day.

PH of water is 5.8 which should be fine.

How exactly can I affect this? Good drainage? I have it in regular pots as always so drainage should be fine. Next time I try to use perlite to be extra sure.

Thanks for any more tips guys!

tips of your leaves are showing too much N with how some are hooking.

They are ment to get dry, If your watering when almost dry thats your problem.
But dont go off what it looks like. You need to be feeling the weight since it can be dry every where except around the middle of the root ball. Which is what suffocates them.
Plants that sized shouldnt need to be watered more then every 3-4 days in those sized pots unless your running really high temps with low humidity. But then youd be having heat stress which makes the leaves roll up the other way.

Seriously overwatered. Lay off the waterings & let them dry out a bit.
:peace:

More coarse sand is the fix for poor draining soil that will give you a base for good soil should you wish to work towards better or organic growing. Although your soil does need more perlite. Throwing Perlite at poor soil is like duct taping something that should be welded. Sand is cheaper also.

"Ph. 5.8 which should be fine". Where did you get that?
"I have it in regular pots.....so drainage should be fine". Pots have nothing to do with drainage. Roots, yes, drainage no.

I use pH 5.8 because they're still young and need to absorb lot of nitrogen which absorbs better at lower pH. Am I being wrong here? And can wrong pH cause this kind of problem?

If you're implying that I need to use more perlite, yeah, maybe you're right, but I've never used it before and I've never had this kind of problem.

Phosphorous, Manganese, and Boron are your low PH. uptake neuts,, Nitrogen works throughout the Ph. scale. I'm not implying you need more perlite, I'm saying you need more perlite, but not as much as you would if you mix some coarse sand into your soil. I don't know the effects of watering in soil at 5.8 because I don't do it. I do know that continued acid baths will scour your soil, and perhaps your plant, removing things that, most likely, are a benefit.

Yes. Continued watering with acidic water will eventually acidify your soil. Especially if you add acidic nutes. But lime or oyster shell should be in the mix to buffer it. You are not likely getting specific uptake from the waters ph. The medium buffers the solution if mixed properly.
