Looks kind of like a potassium deficiency due to the yellowing along the edges and between veins. What medium are you growing in? What are you phing the water to? It might not be that you aren't feeding enough, it could be that the ph you are watering with is locking out that nutrient. You want your water to be around 6.5 ph if you are in soil and 5.8 if you are in a soilless or hydro medium. You can be a little below or above that number but if you are too high or too low the plant cant uptake what it needs.

Slightly Brown Crinkly TipsDose anyone know what could be causing this browning at the leaf edges? It is a bit dry and crinkly to the touch. This is only on the bottom two fan leaves, and only the very tips. All the newer growth looks fine. Nutrient Burn maybe?
Should I be worried, or adjust anything?

Does anyone knows if should I flush the pot ahead of time to reduce nutrients levels?As you can see from last pic from week 6, I have used pre amended soil with 2.5 % of Nitrogen on dry mass. (sorry for the italian).
Should I flush the pot ahead of time in order to reduce nutrients level so to both solve the yellow tips problem and favour the flowering stage?6y ago

Yellowing/purpling leaf tips outdoorsIm experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?
