Potassium deficiency or overwatering??? Need help

PoteyMagots · Oct 15, 2022

First grow ever, lots to learn. Week 5 of flowering and the fan leaves are turning yellow. I've also got brown tips slightly curling down. It gets 1.5L every other day in a 5 gallon fabric pot with nutrients every other watering. My first thought was potassium deficiency this late into flowering. Any input would be very appreciated.

Nute burn? Just top leaves or bottom leaves too? If just top leaves its your light being too close. All leaves nute burn.

I can't tell what part of the plant those leaves are on.

You do have a little nute burn, judging by that last pic. Nothing to be concerned about.

Light burn looks like this

Looks like mag deficiency to me

Is it from the bottom up or did it start top down, or everywhere? That will tell you what to look for.

Bottom up, it's nute related.
Top down, Light/air/wind related.
Everywhere at once, Root related.

Yes, that's an oversimplification, but it is very accurate.

Appreciate the help everyone, awesome app. I did give the recommended "heavy dose" this feeding and from what I've gathered here along with the stage the plant is in, I believe I've got a combination of slight nute burn and a calmag deficiency. I will add the calmag to the next feeding and go light on the nutes and see where I'm at.
