Lots of people say this is natural for seedlings, unless thers obvious leaf damage, and if the plants are still growing, i wouldnt worry too much. Usually its a temp issue but ures seem ok.

so yeah little update the girls doing a bit worst .the leaves drooping and some light yellowing on the edge of leaves,i do not over water them sure, i wait till cups dry out i check inside soil its dry,or very little humidity almost nothing,so maybe underwater even ,the cups was really dry ,i checked inside like with my finger 4 cm and it was dry a lot so i gave 35 ml to each girl ,only water no fertilizer yet,,i was thinking maybe its light i put 600 w hs lamp 60 cm above girls maybe too hot ,i will put light up till 80 cm min,and also intake air pipe blowing directly on girls ,maybe is not good?too cold for them? i don't think its water issues because i gave yesterday to only 1 girl water and no change between the girls all of them looks same ,if it would be water problem the 1 girl i gave water would be better,but she is not all look same,when girls wake up i send pictures ,i use biobizz all mix soil ,the girls r 2 weeks inside cups maybe i should put them in big pots already and start with nutes?
some help please
best regards

Hello. Yes, 600 watts is a lot of light. Keep more like 80 cm when the plants are so small. You need to repot them. Those are very small cups. You are watering every day so their roots are always wet. They don't like that. Also, the light coming through the sides of the cups will slow the root development. What kind of soil do you have? Don't use soil that has nutrients added or you will have problems. Make sure your soil has plenty of drainage. You will have to add nutrients eventually.

to much light intensity/heat from the light get's my vote. They're still small dog, get that light further away! For sure! And yes, like shnkrmn said, lights are bad for the roots. They dont like it!.. A simple layer of duct tape around the outside of the cups would solve that problem. You should be transplanting before to long tho.

hi, i heard that if you grow in soil indoors with a 400w hps lamp and the humidity goes under 40% -30%, you can put some water in a big bowl and put inside the plant pots. but the pots must not touch the water. you must put them 1-2 centem=eters above the water.
is this correct???? thank you.
