Is this nutrient burn?

docpaycestarted grow question 6 months ago

As a beginner it is hard to classify that: Are the brown tips a sign for nutrient burn? Or rather a deficiency of something? Soil pH (out of whack) 7.4ish. Fighting that for weeks now... Soil EC ~ 2000 µS/cm. Crazy Hills fertilizer as scheduled. Thank you!

with that EC you are at the limit without CO2 It looks like a K def, but with that EC and PH it could be a little bit of lockout lower de PH to 7ish or 6.5 will be great.

It’s hard to nail this down. The tips of the leaf looks like it was burnt at one point. Probably due to a period where the medium dried out too much. Never let the medium dry out completely as this will cause nutrient burns to happen. On the other hand I also see every tip on the sides of the leaves also starting to appear a slight bit yellow. Which makes be lean into a little bit of a Potassium deficiency as well. Are you feeding a bloom booster, perhaps increase that dose by 10% on your next two waterings. I hope this helps.

Burning Edges/Yellowing and Drooping?The yellowing has gotten worse and I'm noticing slightly burnt tips/edges and some droop. Could this be burn/deficiency or over/underwatering? A combination? Is there anything I can do to fix this early or is it just a matter of giving them some time and less nutrients? Thanks!
