Can we see a pic of the whole plant please mate?

And what nutrients are you giving it? If its in living soil, you shouldn't be feeding it much

You described the media as supersoil/coco coir. Did you mix the 2 and at what proportion of each if you made the mix. These 2 media usually are run very differently. Coco needs nutrients and Supersoil does not. The 2 also run at different ph levels. What I see looks like some ph problems possibly. Might need to find the happy place for this blended media.

Thanks for replying! I use 1 pound living soil and equal amount of Mothers Earth coco coir / Perlite mix to fill 1/3 of a 5 gallon smart pot removed link mix that together real good and fill the remaining 2/3 with coco coir mix.. that’s it. Ph of soil is 7 and water and cal/mag ph is 6.5

Doing the math I get that the pot contains 5/6 coco and only 1/6 soil, someone can check my math it’s late here. In my opinion this mix needs to be run like coco. One very important thing is coco should always be kept wet, yours looks very dry. Coco should be watered daily. Coco also likes lower ph so I’d keep that ph in the 5.8 to 6.2 range. Coco also needs cal/mag on every watering as the coco alone has a tendency to lock up both of those nutrients. You are in uncharted waters for me, I keep my coco pure, but as your soil level is so low adapt coco grow practices and you have a better chance at success. You are also going to need some coco specific nutrient supplements for this grow as the soil fertility won’t last long. A decent EC meter will be very important if you continue to run coco. It is the main tool to fine tune the feed level of your grow.

The math, yes close enough, the top is dry.. they’re  watered everyday with Cal removed link it’s not dry below the surface.. it’s just the way the air movement is.. I’ll have to check out the coco nutes:. Pretty sure it comes with them in it.. so need to invest in an EC meter! Really appreciate your insight and help! They’re growing very rapidly as autos do, the yellowed and brown spots worried me..
