what is wrong with my seedlings?

The problem came a few days earlier so they had not been transplanted to rockwool when the sympoms occured at first.

My RH was 75-80 % so I lowered it because I thought that it could be te problem.

temps at the plant top is about 22.4 C and

temp where the seed is is about 22.1 C I know this because of the use of a heating mat

These symtoms r showing on 4 out of 8 seedlings

oh yeah I also spray on the tops like 1-2 times a day..

I thought first that it was due to spraying the root it plugs and thefore causing overwatering but i dont think so anymore because the leaves dont hang a bit..

thx in beforehand fellas

it looks like calcium def but they have only been growing for 8 days I didnt think they needed thm nuted at this early stage but do they?

Stop spraying them and give a weak feed with some kind of nutes and cal mag

Stop spraying mate... I was going to say it looks like you spilled something on them.
Just keep the rockwool damp then see how they go.

thanks man ! I just put them in rock wool yesterday that had been soaked in water and nutes at the EC of 0.8 but it was just the regular grow nutes. should I just soak them again in water and calmag at a low EC?
and also why shouldnt I spray them isnt that a good thing to do?

ok

Spraying seedlings heavily like that just isnt needed, you have problems so you need to strip everything back to basics until you work it out.
Stop spraying lol.

Are you under LEDs? Its not uncommon for young plants under LED to ask for food like yours are.

Tbh your whole method sounds too wet. Root plug, rockwool, foliar spray, the plant needs an umbrella and ski boots with you hovering over it lol

okey thanks man I will try to keep it a bit dryer next time haha.
no they´re under a 48 w t5

The thing is that the other 4 seedlings looks perfectly fine thats why i´m a bit confused but it could really be the spraying if the effected ones have been getting alot more water on them..

 

[monstaganja]

but its totally fine to keep the RH at around 75 % right?

Many healthy seedlings have been grown in high humidity. Thats not your problem.
I don't think the spraying is causing the spots, thats caused by a deficiency that will be fixed when they get some nutes into them.
Seedlings only need a tiny bit of water but yours are living in water world hehe.
