cal/mag? or PH imbalance? both?

Hey everyone.

First off I just want to thank you for looking at this thread. Its been awhile since I've ran into a deficiency. But. None of us are perfect. Some of us are picky.. (Like this pheno)

But story goes they are roughly 40-50 days old. They are females. Same seeds, 3 different phenos I'm imagining.. they have been sharing a "run off catch" I measured the run off today. Its sitting at about 1800ppm and 6.5 or so.

So here I am running into what I'm thinking is a cal/mag def. Mainly I'm thinking it's cal/mag because they have been sitting in their pots since they were planted originally so the soil is probably out of micronutrients is what I'm thinking. I haven't added any cal/Mag or ang nutrients up until this day of finding the chlorophyll dying.

Well here's a pic

Thanks everyone for looking. Just ask if there are any questions

Possible manganese?

1800 PPM!!! Uh . . . have you fed this to other plants that made it and produced bud? I'll go out on a limb and say the deficiency is caused by lockout. 1800 PPM in soil is extremely high in my experience. I've never run anything that high even in hydro.

Looks like burn, 1800 is really high. I finish my DWC around 1600. PH should be 5.8 to 6

Well I'm thinking that the 1800 is combined from several other run offs evaporating and leaving behind residues. So I guess that makes sense. Its been a few years since I've grown anything, this is my fist time back since like 09.

But I hear ya. Thanks for the lesson. Just flush them with cal/mag supp. And rebalance pH yea?

Flush like hell with water first. A couple of times at least.They won't be starving with a PPM that high. Then go ahead with your plan.

But yea I've grown all the way through. Just to be clear I'm not giving a solution of 1800 ppm to my plants. That would be genocide. This is sitting in my catch pan. There are three plants in the catch plant. One that's in a 3 gal smart pot freshly transplanted, the other two are in gallon pots. So I'm thinking from watering/seating the fresh transplant into the new 3 gal smart pot, the soil released a ton of nutrients is what I'm thinking.

They drank it up tho. It was a day or two before it was soaked up by the root balls. And the one behind it is fine.. it's the one up front.

So what is your PPM going in?

Like maybe 3-400

Water from the tap is like 210..

I added some cal/mag and took it up to 310 so hopefully and it was ph'd as well down to 7 so the plant could take it then and there
