Burn?

[Cheeba]

Hey plant people,

So what I thought was some dank purple edging on a few top leaves turns out to be burnt edges. Pics below of my tallest hybrid, does it look like light burn, nute burn, some other rookie mistake?

Day 52 flower, 17” from LED, soil, organic nutes, ph’d water. Guessing they need 3 more weeks?

thanks for comments

Looks like a Potassium deficiency likely cause by soil issues. Organic liquid nutes can be challenging.

Any tips for addressing potassium deficiency? Thanks Smokesteve

Hi, any suggestions for handling potassium deficiency for the final 2-3 weeks? 58f today and will begin flush on day 60 for WW and a week later for G13. Thanks.

It's tough because you are using organic liquid feed. Honestly I'm not much into the flush thing anyways but being that you are so close not sure there is much you can do anyways. Sorry.
