Returned from weekend away to notice this :(

[AutoManCan]

Hello all

Autoflowers on day 15 of growth so far.
I watered the plants using root stim and water on day 12 and have been away since.
They were suffering from heat stress earlier in the week but it has now been remedied.

I get home to notice one plant is doing well but the other is very pale and has burnt all towards the ends. Hoping someone can diagnose this for me





The other plant seems perfectly fine

Have you sprayed them with anything? The last few pics look like something shining or white on the leaves

And heat stress on them leaves
But I have no idea what those spots are fella

[AutoManCan]

No there is nothing on the leaves, no white spray.
On the first two pics there is 1 or 2 water droplets from filling my humidifier but I gently shook them off.

They look a little hungry and the second one, especially, looks hot.

suffering from lack of love while you were away, get back to giving them love they should pick up, treat them gently

What you growing in, soil or coco? What you feeding 'em? What's EC & PH?

Growing in soil, not used any muted as they are only 15 days old. Surely there is enough food in the soil still?

Which soil are you using? Could be too hot for the plant....
