Did I over fertilize?
 

I think this is from to much fertilizer any idea on how to correct it ?

Re: Did I over fertilize?
 

My guess looks like something is eating the leaf i think the leaves would be turning black or brown just a guess.

I think i would pour the water to it and hold of on the fertilizer.

I am pretty sure nothing is eating at them. I gave them a micronutrient supplement and I think they were already getting plenty in the regular fertilizer. So no more fert for awhile. Thanks

Mine yung bananas look like that i was fertilizing 3 times a week so i stopped all fertilizing and started watering every day and now they look allot better.

This is mainly a calcium deficiency. A quick fix is to apply calcium nitrate fertilizer.

Long-term, use ag lime and a banana fertilizer having all minor elements. You may need to add extra boron eventually.

When a plant has too much nitrogen, it can outgrow the available calcium supply; hence one thinks the odd symptoms you see are due to over-fertilizing.

Thanks Scot

I figured it was some dificiency , but I wasn't sure. Could I have over applied some fertilizer to cause this. Like to much 0-0-50.

Is this something K-Mag or Azomite might fix?
I have been mixing my fertilizer's with Azomite. I have not seen any neg affects, I have been matching 1Tbsp Fertilizer to 1Tbsp Azomite.

Richard suggested I add ag. lime when I fertilize.I bought some and forgot to use it . Won't happen again.

Re: Did I over fertilize?
 

Saturday I put down some ag.lime and gave the plants a folair spray of calcium supplement. We will see what happens.

Please update us in a few weeks. :03:

Re: Did I over fertilize?
 

Aside from lime can you name some calcium supplements so I don't have to sit there scratching my head in front of the fertilizers for 20 minutes :03:

Re: Did I over fertilize?
 

. I will let someone else answer that one. Got a liquid supplement from Richard. Will update when I see any change in the leaves.

Re: Did I over fertilize?
 

At a retail nursery you can often find calcium supplements among the Cacti & Succulent products. From a farm supply wholesaler you can find both water soluble and liquid calcium supplements. For example, I provided Tony (sunfish) with a Grow More product that is 25% Calcium chelated in lignosulfonates. It's $3 a quart -- if any one else is interested send me an email and I'll put on my website.

I just use gypsum. Lime will raise my pH which is something I don't want to do since it's already around 6.9-7.2.

I also have used a commercial liquid fertilizer CAN-17 but I don't think it's available retail.

Re: Did I over fertilize?
 

Just checked soil ph it's 5. So sould I apply more ag lime?

Re: Did I over fertilize?
 

You might check the pH of the Ag lime to find out if it is alkaline or neutral. Start with a tablespoon a week and stop in the week the pH reaches 5.5. The Ag lime breaks down slowly so when it reaches 5.5 the pH is still rising.

Tony, the city water at your location is slightly alkaline. Consequently you will also raise the pH slightly every time you water.

Re: Did I over fertilize?
 

Wow! Yes! A pH that low is pretty rare in California except in areas where farmers have applied lots of ammonium sulfate.

A low pH like that is great for phosphorus being made more available but it's detrimental for some other nutrients as well as some beneficial microbial life.

It's usually best to also check your water pH but with a soil pH that low you have a lot of capacity to buffer even a moderately high water pH.

Re: Did I over fertilize?
 

Could this be from me over using to much ammonium nitrate. I have the can 27 . My soil is clay.

Re: Did I over fertilize?
 

Tony, I don't believe ammonium nitrate has a big effect on pH. I'm surprised you can get it, though. Since the bombing in Oklahoma City the two ag suppliers near me quit carrying it because of the additional security required by some additional regulations.

Richard, are you saying that some sources of lime are neutral? Lime is widely used in agriculture to raise pH and I've never heard of a form that isn't alkaline.
