What do you think this is? Yellow on the outside of leaf

A couple of my first year hops have some signs of something happening and I am not sure what is happening.

Take a look at these pics.

This is a leaf from my Willamette which is my strongest grower, but the lower part of the plant has quite a few leafs like this one

This is my centennial and is only about 4 inches tall and has been like that for the last month and a half

They are on a drip system (1 GPH) and get 8-10 minutes, 3 times a day so about a half gallon. Is this too much? It is hot here, been hovering between 90 and 100+ lately and going to get worse as summer comes.

When I planted I mixed in compost with the soil about a foot deep and like I mentioned these are only 2 out of 5 that are above ground right now. The other 3 are doing just fine, well as far as their leafs.

It could be it's lacking calcium but I would pick up a soil tester to see. Also try one of those meters to see if it's too wet or too dry.
Wood ashes would give both iron and calcium to the soil.

That is what I gathered from the homebrewers garden book. They said you could add a limestone (don't remember the specific kind) or wood ashes which I have around so I added some the other day but wasn't sure how much to add. Anyways, we will see what happens.

Should I pull off the bad leaves or let them go?

My cascade is doing that as well. As far as adding calcium goes (maybe a dumb question) could I just crush up some tums (antacid tablets) and sprinkle on top of the soil?

Looks like the beginnings of Potassium deficiency but, that doesn;t mean you need to boost potassium. It could just mean what availabel is bound up in the soil by pH or salinity.

And we thought water chemistry was the hardest part of brewing.

Mine will show those same signs if I'm getting too much water on the leaf itself.

I've read that some people trim off the lower leaves anyway but I'm not sure if it matters or not.

That's typically what I do in mid/late June. Helps keep out clutter

So what about the Centennial? It sprouted days after planting in late March and quickly grew the 3-4" that it is still at now 2 months later.

I think I may be watering too much and turned off the water for today even though they got hit with some sprinkler water this morning they will go without the drip for today and I will check them out tomorrow.

Have your temps dropped any in the past two months?
