Potassium level is too high and antagonising Magnesium uptake.
Calcium is too high and antagonising Magnesium.
Nitrogen from NH4 form decreases Calcium uptake.

These seem to be the most likely potential culprits.

It was Excess K, which caused both Ca and Mg uptake issues. I corrected it easily.

I ran an EC of 2.5-3.0 for sometime to see how high I could push it without adverse affects.

When I noticed the BER on top of the Mg deficiency I knew what was happening. First I cut out the KNO3, then simply reduced the 4-18-38 till my EC was 2.0-2.2. The plants look good, fruit production is still good too.

I posted this because it is good to know your element antagonists. When you see a deficiency many times it may not be a lack of, but an excess of. It is important to use an EC or PPM meter when growing in containers, or know your antagonists. Thanks, that was fun. LOL

I was gonna say that maybe you doubled your Kno3 by mistake when mixing up stock tanks.
But you did it on purpose lol.

I also ran a 2.3 EC on seedlings, they did just fine. LOL A guy up the road uses the same mix on seedlings as well as mature plants, and his plants look great.

Mark -- I thought I could hear some of your outdoor tomatoes splitting in all this darned rain! I think we are scheduled for 1-1/2 days of not-rain, then more rain. Ack! My outdoor tomatoes are looking rough.

Mark - Re: your comment having the tops hacked, mean the same as having them topped to minimize their height? or is it because the season is ending?

I think I remember your season goes long into the fall.

Tomatoes look great as they always do.

We finally got some sun Sherry, yay. I am surprised that more have not cracked with all of the rain we have had. The birds don't help either.

AKmark · August 29, 2018

We are winding down, but still have a few tomatoes to pick

Barb_FL · August 29, 2018

A few???? ha ha.

Winding down, meaning done for the year? I thought you went way longer.

Did you have a successful season for your standards?

Your plants look great.

We will run a couple of GH's into October, but have to start cleaning some out within two weeks. It take a couple of days to clean each one up and sterilize it.

I had about an average season, some surprises, mostly just the same ole.

What I really accomplished this year was a narrowing of market quality varieties. Next year I will grow less than 10 varieties, most will be the crosses that Sherry and I have worked on. They are simply earlier, produce great, less cracking, and we captured the taste of the heirlooms used, and then some.

I am going to do the following hybrids too. Big Beef, Tomimaru Muchoo, Damsel, and some cherries which will be U pick.

I need to continue to improve management practices, pruning comes to mind, and I need to split up hybrids and heirlooms into different GH's. They have slightly different fertilizer needs.

Next year I will send off monthly leaf samples throughout the entire season, then I will have numbers that pertain to my daylight changes.

I am installing low CFM fans in each GH to vent all night, these will help keep humidity down at night.

All in all I am mostly happy with my season, but I can do much better too. The more GH's the more I rely on others, that can be an issue too.

Next year I am doing much more outside, it is going to be a challenge.

Great looking "Winding down", agree with Barb.

imp · August 30, 2018

Mark, back 1 page on page 16, the last post, is that an orange tomato or still ripening to red?

AKmark · August 30, 2018

That is Yellow Brandywine. Late in the summer they smooth out and are a great market tomato. In the spring they are ugly and I want to chop them down. LOL
