Seedling Issues [Help]

Well in the UK we've hit a bit of a heatwave compared to usual..

Temps in my grow area have reached a max of 87.6
Ever since the weather a few seedlings have took a turn for the worst.

Soil: John Innes No. 3
Currently watering with filtered water

Pics are abit out of focus sorry.
Got droopiness and curling.


Can anyone confirm symptoms ?

-bump.... anyone???

any reply will be appreciated.

Anyone??????

Looks like heat stress.

What type of soil, did you use nutes, how often are you watering? How far and what type of light are us using?

Posted soil before, John Innes No.3 it contains some slow release nutes but im watering with filtered water usually every 2 days.
John Innes No.3 soil PH is 6.5 - 7
Im not actually feeding any nutes. I know my soil isn't the best for starting seedlings but im pretty sure it's just the heat.
Currently using x2 125w CFL with reflectors plus ive got more side lighting. got it very close, but have raised for now due to the weather we are having.
Will be using HPS for flowering.

This is your problem, seelings need no nutes at all they make seedling soil, you have them in soil for mature foliage plants you are burning them up. Use seedling soil in a solo cup until they have five or six sets of leaves and the roots are coming out of the holes in the bottom of the cup. You threw babies into a gunfight they cant win. Might not be too late for them get them out of that soil into cups and seedling soil and hope for the best is all you can do.

Thanks for your reply, I had a rough idea in my head this could be a problem. I will do as you advised immediately.
