New Grower Calmag deficiency ??

[Jovinn]

I sympathize, I've been having the exact same problem. Suspected CA deficiency, added CalMag, didn't help, leaving it out didn't help. I'm in dwc, but also using Flora. I'm baffled. Good luck...

A possible explanation is that you spilled a little fertilizer solution on those leaves.

Any good fertilizer, properly used, should produce no deficiencies (but some don't have quite enough calmag).
Messing with elements other than calmag will lead to confusion, and possible problems.

When I water I ALWAYS make sure not to get anything on the leaves, and if some water ends up splashing on the leaves I wipe it of with paper towels, so it can’t be that..

When you added calmag spots didn’t stop appearing on the leaves ? Did all the leaves end up doing this ?

Nope, no difference detetectable. It is only affecting the older leaves, not consistently, it seems like the plant is mobilizing it out of the older leaves into the new. Has been ongoing, but plants are mainly outgrowing it. I considered a foliar application of Ca, but didn't get around to it. I never had Ca issues before, the only difference is I'm using leds, and auto flowers with 2/3 strength nutes. Mog suggested I was somehow getting lockout, but I've been very careful mixing.

So I defoliated a ton and it’s now affecting newer growth. I’m going to spray 1 with 5ml/gal CaliMagic and see

Adding more calmag more than likely won't help, especially with excess N, as most calmags also contain N. I would agree with @Mañ'O'Green, IMO I would 100% say this is lockout, NOT a deficiency. Adding to what you've already got going it going to make things worse.

I agree with you cali magic does have n in it

• Total Nitrogen (N) 1.0%
  • 1.0% Nitrate Nitrogen
• Calcium (Ca) 5.0%
• Magnesium (Mg) 1.5%
  • 1.5% Water Soluble Magnesium
• Iron (Fe) 0.1%
  • 0.1% Chelated Iron (Fe)

I alway give plain ph balanced water between every feeding, forgot to mention that, last week I also flushed the soil before starting increasing the flowering nutrients

In soil a feed water feed water schedule is too much IMO. I believe @Mañ'O'Green has said that a feed water water feed or feed water water water feed schedule is more appropriate though I can't remember with 100% certainty.

I have no idea I don’t have a soil ph meter :/
I have been watering with water between 6 and 6.8 though

Hello what PH pen do you have? cheap one or a good one

So far I hadn't had any problems like this so I though water feed water feed was fine, but yeah I think now I'll add another water after each feed
