Got a plant with a deficiency that I ran into a month ago I thought I figured it out and fixed it once but know I start to question myself, the browning starts at the new growth and on the leaf edges, I started the run trying to do a diy/knf ferments and living soil after some time I ran into this problem because I didn't have all the inputs and didn't top dress so I bought some age old nutrients to substitute what I don't have so I wouldn't kill my girls

Container size 26 liter

Soil is 30% kekkila peat moss 30% organic compost 30% airetion I used red basalt.

I water based on the weight of the pot it's about once every 4 or 5 days

Last water was two days ago with compost tea made with compost age old nutrients bloom and kelp at 2ml each for 6 liters and threw a little bokashi I have ,this compost tea could be the problem though I am not sure after I watered with it I realized that I didn't check for e.c and ppm and took the e.c pen and it was 3.3 I hope that it's not the cause for this

That looks like a potassium (K) deficiency. Maybe add some flowering nutrients next time you water.

Hey man thanks for responding actually I did in the last age old bloom it's npk is 5.10.5 but the browning starts at the top growth so could be calcium but not sure

Thanks man I at first didn't see the k but after a few more looks I saw a k Def and the browning in the top was a late sign just did a foliar spray with the bloom and kelp from age old nutrients added some lab and aloe hope to hold it back till the next feed

So guys the problem has appeared again and that can't be a k deficiency cause I have had bumped up the feeding I mean 😅 how can it be a k deficiency something is not right so I made a run off collector so the run off is 6.4 p.h and 6.6 e.c!?!?!? Is that my problem cause I don't know if that's OK in the soil?
