First attempt - Nitrogen deficiency?

Hello guys,

Its my first grow ever, and babies started getting bottom leaves yellowed, and then going up to anothers. After some research, I think it is a nitrogen deficiency, what do you guys say?

I feed them 2.5ml/L Biogrow, 2ml/L Bioheaven and 2ml/L Alg-A-Mic, BioBizz ferts. (I started after the very first pair of leaves turned yellow).

I dont know what to do now..

Light: 18/6 240w qb, 40cm above them
Medium: Peat + Perlite
Temp: 25-27 C
Humidity: 50-55%
Planted in 9L pots - the bigger plant is in a 11L one
80x80x160cm tent

Thanks in advance for your help!

Pictures would be more helpful. Also, medium, temp, humidity info.

3 of them are in 9 liter pots, the bigger one (last right photo) in 11 liter pot

About the mud/overwatering, is there something I should do? Or just wait for it to dry and water less on future?
he meant me when he said "agree with mud" it's like a nickname.
they're stunted and will look like that until they pop out of it (usually a week or two)
don't water them so 'frequently' those pots hold a LOT of water for tiny plants.

oh didn't notice hehe :bigjoint:

okay, I'll take more care on that and hope they can get over it, thanks for the info!

What’s your medium? Plant looks small/young for pot and your already feeding….if you mean by first leaves , the cotyledons, that’s normal and what the plant uses until true leaves are formed . Most decent soil contains 3-4 weeks of feed

I'm using peat+perlite 50/50, yes I meant the cotyledons. Do I transplant them to smaller pots? Would it help?
 
Whats your PH? Peat is very acidic
Im using a 7ph tap water, but BioBizz ferts dont require to control it since its organic etc, right?

Overwatered and overfed. Your autoflowers are already flowering as well. Extremely small for that already so you need to focus on the basics.
Sadly I dont have any information of the strain, didn't even know they were auto (nice), just know they produce very purple buds. Maybe the overwatering delayed the growth stage too much (30ish day old)? They also started outdoors at the balcony and 10-15 days later moved into a tent, were receicing too little light due to weather. :sad:

You're missing the compost.

Also Biobizz Biogrow is basically expensive molasses it sounds like.

Peat is also super low in pH like @jimihendrix1 just said.
 
I dont agree about not worrying about PH. Peat has a PH of 4.4

I can control PH with no problems, but if so, what would I use for it? Saw that organics like vinegar/baking soda are good with BioBizz to PH, do I stick with that or chemicals like sodium hydroxide/phosphoric acid?

Also, restarting the grow is a thing? Or better keep them, considering they will veg for much longer time than usual?

Jeez, so many questions, sorry man haha

I'll attach some new photos

You can control the pH going in, but you have no idea what the actual soil pH is.

And that 3rd pic? It looks like it's flowering already. Am I not seeing that right?
