Need help please!! Leaves getting brown spots and then drying up and turning yellow?!

[youngxgreen]

Growing in soil for the last 5 weeks, still in veg(18 hours of light). Been using bio-grow and calmag for the last 2-3 weeks. My first grow ever. Didnt have much money to spend so basically made a grow box out of cardboard. Two fans with filters, one taking air in, one out. Help please!!

really tough to say without more info but i think you need to pot up that's a big plant. and from the leaves i'd think maybe potassium deficiency. just my thoughts at first glance.

Well is that peat moss or ? add some perlite soil is bad needs more drainage and bigger pot with holes in it. Some things like pots you can get by but soil is another. It's got to be light fluffy well draining.

Do you have a pH meter or test kit?

 

[CaptainWiese91]

PH levels ?
what type of soil are you using ?
You need a transplant really soon.
again like the others say, hard to know without more info?
What about perlite or leca in the soil ? And how much drainage you got in that pot ?

Thanks for the responses guys. So cause im on a budget i didnt have enough for a ph tester at the time( ik that was risky but i just ordered one so hopefully it comes quickly). The soil is just an all purpose soil that i got from b and q(hardware store) but i got some more from bio-bizz with perlite mixed in was just waiting to use when transplanting to a bigger pot. I would say the pots got pretty good drainage as i've watered before and waters then seeped out of the bottom of the pot. As for the peat moss? Not too sure what this is ngl( first time growing so dont really have an idea) would it be worth removing or does it not really affect it? Again thanks guys.

PH meter is your best friend when growing Cannabis 😎
when you transplant- make sure you have enough perlite in it. The plant will thank you.
you maybe have a lockout of some nutrients 🤔

put about 100 holes in the pot so your roots can get air. The peat moss was brought up because of the green showing on your root ball if its growing fungus on it thats not good. if it's peat moss in the soil its ok. im going to assume it's not peat moss

 

[Gjourney101]

Yeah if that's no peat moss you might wanna do a hop and a skip cause there's a bigger problem on hand

The plant is showing various different symptoms so I also think the ph must be off balance.
