Yellow leaf tips first time flowering

My fan leaves are all turning brown Wtf. I just started giving nutes is this the problem?

what are you feeding it and how much? How old is the plant?

Help us help you ...
Please provide more information.

I am using a product called schultz plant food its 10% n 15% p 10% k the plants are in their 4th week of flower. Any other info needed just ask and ill tell ya. As this is my first grow I have made a lot of mistakes such as my lights were way to high and I just started nuting. I appreciate the help I'm kinda at my wits end here I just seem to be screwing up a lot on this grow and I'm kinda worried about killing em. I've watched em grow these last couple of months and now that buds are starting to form I would hate to lose em.

It's probably low PH. I'm seeing this issue on these boards a lot lately and had the problem myself. Buy sulfate at the garden section of lowe's and it should straighten it out. It's the stuff that turns audreangea's (sp?) blue.

So should I flush or no?

Aluminum sulfate (the stuff that turns hydrangeas blue) is a soil sourer ... it lowers pH. Dolomite lime buffers pH upward. cn

dont worry.... they look fine. Just low on nutes, imo nitrogen causing older leaves to yellow. KEep what ur doing, add a nitrogen high fert dose, and relax

IDK how i feel about 10-15-10.... im no expert but thats diff from my ratio in my ferts.

I was assuming it was too alkaline, as was with mine. If it's too high then no, no sulfate. Sorry for not clarifying. Is there anything else that one might put into their soil besides that to lower ph permanently? wow, I butchered "hydrangeas" pretty bad...this smoke isn't even that good...

What's your ratio rockin rage against?
