Hope it's ok if I ask a question about an issue with one of my plants that I have been feeding every watering. I have been using TTF per the instructions which say on containers to use with every watering for 2 to 3 weeks and then plain water for 2 to 3 waterings then repeat.

One plant has possible chlorosis but I'm not sure the cause...

First noticed it a week ago, see circled part of photo.


Here it is last night and this morning




My plants were started later than Barb's (I live an hour north of her), and took a hit from the hurricane but bounced back and they have tons of blossoms and really good fruit set so far. But they are probably two months behind most of hers. So far this is the only plant showing the symptoms. They are in EB's and I dont understand the whole continuous feed concept yet, so for now I feed about 2 tablespoons of TTF every other day when I water.

My fruit set is great so far (really just beginning but tons of blossoms and almost none dropping).







So far only one of the two plants in that same earthbox are showing the symptoms and no other plants in any other EB'S have the symptoms.

Sorry for jumping on this thread but since I am feeding every watering thought you guys might know what the issue is.

I would judge it to be mag deficiency, but in my own set-up I would wonder why I'm not seeing it in other plants.

I know so little though, most times I just throw something out there to see if someone corrects me.

Ginny, I also answered that it looks like a mag deficiency, and maybe 2 other things, a dew minutes ago in the Floridans thread.
Did I read somewhere that you supplement with Calcinit?

[Fiishergurl]

Marsha i havent supplemented with anything this season since Ive been feeding the TTF about every watering with a break for a few waterings after 3 weeks.

Ricky thanks for the input.

I wonder how much and what I should use to supplement the mag?

What are you all using again?

Sorry Marsha, I responded here before I saw your detailed post in FL.

No problem.

Take note that Magnesium deficiency appears on old leaves first.

This explains why.

I still think that's what it is. Green veins and intervenal chlorosis.

Maybe iron deficiency?

Mark, all I could read about Magnesium on that page you linked other than that it was a secondary nutrient, was on that charts saying it was somewhat mobile. I saw nothing explaining why on older leaves , but I know that it may be on older leaves first some but not all the time, and it eventually shows up on some of the other Ieaves. Can you tell more, or have a different more detailed link?

Ginger, you may have missed these sentences

(The mobility of a nutrient in the plant determines where deficiency symptoms show up.

Nutrients that are mobile in the plant will move to new growth areas, so the deficiency symptoms will first show up in older leaves.)

Yes, it can be on newer growth, but at that stage it is usually really bad

That was my thought, I had it mildly on Cosmonaut Volkov's and it presented as mottling on the older lower leaves and not in full chlorosis like the pics. And, this is one branch of one plant, kind of odd.

I did miss those sentences. Thank you. Good read.

Manganese? Per Haifa's website.

Jpop, I felt as though I would get better coverage of the surface area of the top of the bag/soil, then the solution we be more evenly distributed throughout the soil. I feel like on a horizontal bag, the solution would stay on the side of the bag of the dripper and not flow or wick enough to the other sidewall and down 100%. In a horizontal layflat grow bag, drippers would work due to the shape and orientation of the bag.

With straight hydro/no-soil system, a dripper would be fine b/c you are dealing with more capillary action and mabey a reservoir at the bottom of the container.
