Any idea what this is? Brown from leaf tips and edges.

I recently transplanted in a 1 gallon pot. The affected leaves are turning brown from the tips near the middle of the plant. Starts at tips and edges and works itself inward.
Gave it 1/4 strength veg nutes when transplanted (GO Box)
(sorry for blurry pics)

This is how it starts..


Then progresses to this...


Thanks RIU!

well the more experienced folks here usu ask for more info. but i ll give my 2c. if the leaf stems are purple and ur in flowering potassium def. Next choice cal/mag def. the way i d attack it is get ur ph correct. test water in and waste, and soil. once that is good use wtvr ur fav source of k is. i stewed some banana peels and added it to an aac tea. larger plants have responded better than smaller ones. also from what i ve read here et al, the damaged leaves will not repair. look to the new growth. even still progress is slow. if its potassium make sure temps r good(70's, and not below 60f). just my 2nd grow

organic - not checking or bother with PH.
It's a 3 week old clone in the veg state. I may give it an AACT soon.
thanks

GJ,
Usually when you get leaf necrosis at the tip...it's due to nutrient burn. Yes it can happen in organics most usually in young plants. Should grow out of it.

If more tea makes it worse, back off. Or you could just back off without burning it some more...

That was my first thought since I noticed it after the last time I watered.
Next time I'll feed plain water.
Thanks JD
