Need Help!! slow growth - leaves rolling

Ok so both plants show a really slow grow, it's a auto #1. also just now i noticed leaves rolling up, so something is definitely wrong. Girls are in BioBizz light mix. temp 75-78 day time, 68-70 night time, humidity around 50-55. Using Led light. Could it be nutrient burn? Since i read that even light mix can be too heavy for autos at the start? also they're growing way slower than supposed to, i believe it's a day 14 for one plant and day 9 for another please give me some ideas what should i do

Anyone? am i overwatering? or whats going on?

I'm a noob but, what I see are the edges of leaves are starting to curl upwards. I would say the onset of to much nutes.For me I would only give ph'd water. No nutes. Let the pots dry out to prevent over watering. Hopfully someone else with more experience can chime in

Thanks for a quick reply. i'm not adding any nutes, i believe it's a Biobizz light mix that is a bit harsh for autoflower.. anyways i will not water them for 3 days and see if that changes the situation..

dont water till the pot dries out almost completly. then only use ph'd water

Update!! 2 Days of no water, soil is still damp, swiched the lights from weak led to T5, that's whats going on now.. i still believe it might be a nute burn, any help would be appreciated

Picture of a full set up, all three plants are still in early veg, again i'm a first time grower, so any advice would be useful..

also waiting for HPS dual spectrum 250w to come in, as soon as they grow a bit i'll switch to that.

dont water yet. wait till it is dry not damp, make the roots search for water. ive read the rule of thumb is put your finger in about an inch or 2 and if its dry then its good to water.

with your small pots it could be less distance down,

Still no water, looking better already! hope that solves all of the problems.. just that it still looks to me that they grow a bit slow, but i guess we'll see what happens in a week or so..

See this thread and my links and the one pinned right above you on moisture stress.

Considering all cultural factors are in place, if it's growing slow, it may need more N. Cannabis is a flowering tropical foliage plant that flowers like the rest of them. Treat it as such.

I don't like the peat pots. For starts the height restricts the tap root and unless they are kept constantly wet, the roots will not punch thru the peat material except maybe at the bottom (which is always wet). When you upcan make sure you scarify the sides with a sharp knife and bury the plant so that no peat is above ground. If it is, it will wick moisture away from the plants.

Good luck,
