Curling up leaves and brown spots on young plant

[veroxas]

Hello everyone, I am growing for the first time and need some help with my little baby. It is 12 days old and started to show some distress signs like leaves clawing up and small brown spots appearing on bottom leaves. It's planted in verve multipurpose compost from B&Q and I was silly to use some of miracle-gro slow release nutrient granules (8g) around planing hole. I haven't fed the plant yet and watered with ph6.5 water. Soil ph seems to be alkalinic at 8, which i flushed with water once and still no effect on adjusting ph, though soil stayed very wet for pretty long time. Light is LED 50W and was very close to plant for 24/7 most of the time. Humidity is at 49%.
I moved the light up a bit for now, I'm not sure what else I can do to make it better... I suspect possible nutrient toxicity from concentrated miracle-gro granules at wrong PH some may become more available I heard and that would be a huge problem... Other thought perhaps drowned the roots when I flushed soil to lower Ph, or wrong soil because of high alkalinity, even though I read this compost is fine for cannabis.

I need help from experienced growers with this matter as I'm really lost at the moment.

I uploaded some photos to show the symptoms.

Thanks guys!

Any chance you can pot her up into fresh medium and try rinse out some of the miracle grow stuff before putting into the new pot?

I dont think things look too bad and you could probably just carry on just watering for a little while till it goes away

If you're worried I would just pot up like gmo said, honestly doesn't look bad at all though

This happened because you've given extra feed to already rich of nutrients soil. As said above you can either try to flush nicely or just pot her up into bigger pot without adding any miracle grow :) Let us know how it goes. What LED are you using?

Thank you guys for all the advice. I would really like to avoid repoting as I dont know how much roots have grown and wouldn't want to damage them while takign the plant out and stress it out even more, also it's already in the pot that I'm planning to grow all the way (doing microgrowing). Plant itself is in 15cm (6") pot inside the cabinet 22cm (8.6") x 27cm (10") x 75 cm (30") and I'm using full spectrum 50W led light with additinal 50W blue+red+green spectrum to add later if needed. Plant is autoflower by the way.
Do you guys think when plant grows bigger it will naturally require more nutrients and it will balance out? If plant will stay healthy enough till that stage.

You should be fine in the same pot, transplanting would be a bad idea anyways since it's an autoflower just keep with water only for now, let us know how it progresses

Looks healthier than my 1st auto grow

Small pots usually do well with Canna A+B, or like bottled nutrients don't they guys? (Not a bottle fertilizer user myself)

That verve compost is pretty rich in nutritients just on its own. I did have problems with bugs in my soil last time I used it though. Maybe worth checking under the leaves regarding the brown spots.

Otherwise that's a healthy plant!

Maybe worth while telling the actual power draw of your LED though:

Like how many AMP'S it pulls at the wall? Or how much PAR/Lumens it gives out.

Much like it does here:

Or give the specific light model.

Happy growing

I've missed the fact it's an autoflower for some reason didn't see in the first post. How is she doing? |Getting any better or same?

@Bulls only got mentioned later on.

Oh and curling up is usually a sign of heat stress.
