Growing indoors
She's a baby (3 weeks now) autoflowering strain in a 3 gal pot. Yesterday I watered it properly for the first time (watered until I got drip on the bottom of the pot)
Growing in soil.

I got this problem:

Older leaves look like this and are drying out while there is still healthy-looking new growth. She responded very well to nutrients. The first leafset is almost completely dried out I think I might have to remove them :( Help pls

over watering?

It's been like this for a couple of days. And I've only properly watered yesterday. I searched the info and overwatering looks a lot different on other plants (all leaves look lifeless). However new growth looks perfectly fine. In fact, she's fattened up quite a bit since yesterday under a 45 Watt CFL. I would like to provide more info but I wouldn't know where to begin. First grow btw.

What's your soil mix? What nutes do you use? do you test PH value?

No I did not test PH value. Nutes are 7-3-5. I threw away the packaging for the soil but from what I can recall it wasn't hot; PH 6-7

kinda looks like Phosphorus deficiency.
what are you feeding them?

I figured phosphorus def too at first, which is when I started giving it 7-3-5 nutes. Do you think I should go with "bloom" nutes?

Always use perlite in soil,youve created a perfect home for pythium,it can only live in anaerobic conditions.

Makes perfect sense. I do have some good news though: I trimmed off the bad leaves and she's looking better than ever. I used the pot within a pot method to avoid overwatering and when I removed the inner pot I may have damaged some of the roots and she's recovering... only a theory based on how good she's doing now :D anyway in my future grows I am definitely looking into perlite
