Issue with leaves diagnosis?

FatBoyVik · Jan 18, 2025

Hello,

I have a couple smaller plants in veg and they are recently having an issue with their leaves.

They are in coco and are being fed 1.4ec of canna coco and a little cal mag.

The temps are 24-26 C and humidity is above 60% atm.

I feel like I've seen this a long time ago but I can't remember does any body recognise this?

Any help would be appreciated!

What is your feeding schedule?

Once a day so far they are in very small pots and it's not drying out as they are young. Get alot of run off also.

Are you removing the run off? Can see it in the pics.

Skip the Calmag. It's already in the base formula(Coco A+B). Adding more won't make the plant grow faster. It's even contra productive to add on top of a formula specifically made for Coco coir.

Do you use tap water and do you pH your solution?

Cheers!

Yes. Run off is removed every few days but the bottom of the pots are half way up the airpot so roots are too high to touch any run off water.

I use two parts RO water and one part Tap water. Which gets an ec of 0.2. I PH to about 6.1

Every few days as in it sits there for days?

Have you checked the roots at the bottom? I’ve used those pots before and had roots extending down into the runoff. If it’s dark and humid enough roots can reach.

I would look under the pots and make sure roots are ok
