Please help seedlings dying!!

Hi,

i am am a first time grower looking to grow indoors and then plant outdoors once my plants are 6 weeks old in the UK. I am growing 20 plants (6 world of seeds amnesia, 6 feminised super cheese, 5 auto skunk, 1 Big Bang 2, 1 auto critical and 1 white widow).

i used the tissue method and was very pleased to have all 20 seeds germinate that have all now been planted in 5cm pots into miracle gro potting mix which is root boosting compost. On Saturday 2 of my plants died because I accidentally placed the led lighting system with red and blue lights to far away and they stretched to much and the top of the stem thinned and the plants collapsed and dried out. I have moved the light closer about 3 inches from my plants as it doesn't get hot and they seem to be loving it. However this morning I noticed that another has thinned and collapsed which means the light cannot be the problem.

i am growing in an airing cupboard/boiler room which is pretty warm inside and I have also set up a 6inch fan inside to try and strengthen the stems but lost another plant. I have also noticed brown dots on the leaves as well. I have the light and fan on an 18/6 consistent timer. I have been watering the plants 2-3 times a day because the soil is getting dried out fast spraying them with one of those spray bottles 5 sprays on each plant making sure the PH of water is 6.5. This morning I tried something different I got a 5ml medicine syringe and squirted 2 full syringes of water on each plant to see if the soil holds the moisture better.

i now only have 15 plants left and fear that these will follow in the other 5 footsteps if I do not find out the issue.

I am on my iPad at the mo but I will add some pics later.

please help me lol

thanks

A lot of people have problems with miracle grow, search it up using the search bar mate, aparently burns the roots, that might be ur problem try changing to seedling and cutting compost can pick it up at homebase for a fiver
