Indoor 1st Mephisto grow...dwc & coco

[Dublegendz]

Awesome! It sounds like you’ve got pH firmly under control, and that’s more than half the battle. The rest is easy. Look at your water, nutrient strength, and especially cal mag strength.

LEDs increase calmag needs. Not sure what the science is behind it, but LED/calmag issues go hand in hand. Here are a few pics from when my ladies were ailing. I ended up clamping down on the pH and really increasing the calmag dose. I also made sure my roots were never exposed more than an inch to the air below the netpot. And lastly, let the pH drift the entire range from 5.75 to 6.25. There are a few sweet spots in there for different nutrient uptake. Hope this helps.

You're the 2nd person I've heard say that about LED's. There's gotta be something to it & clearly our deficiencies are identical. I'm already at 3ml/ga of calmag...how much higher would you suggest I go?

Changed out the res...upped her to a 750ppm feed but thanks to a man wiser than myself, I'm realizing that normal doses of calmag aren't enough under LED's so I'll have to up it to about 4-5ml/gal. Also had to McGuyver her roots free...were tangled in the air lines

My cal mag product listed 3-5 mL/gallon. I fed at 5 mL per gallon. The problems stopped. Later, as they got to be insanely huge on full strength nutes, I’d be a bit sloppy and pour 6.

In addition, I use my tap water which packs an additional 320 ppm, mostly cal and mag.

That’s a lot of calmag. But between hydro, their size, and cobs beaming down on them from all angles, that’s what it takes my ladies. I’ve tried intermittently to notch the dose down and within a few days I’ll start seeing the tiniest bits of a return:

I’m just happy I found the solution in a bottle. Fixed the worst week of my grow.

So you doubled the calmag. That oughta do the trick. She should respond quickly for you. It is kind of odd that coco girl is just fine. I don’t understand that part.

Ok well the coco plant (Walter White) is starting to show calmag deficiencies...not as bad as the dwc but subtlety getting worse. I added 5ml calmag to a gallon of plain ro water & gave her a lil this morning. It's crazy how very different these strains are. The fan leaves on WW are huge...branches are twice as thick. I'm thinkin it's almost time to low stress Walter as he's already outgrown the smart pot. I've never done LST before cuz I've never had height restrictions til now. I'm sure i can find a YouTube video or two on how to bend branches without doing any damage. Well here's a lil root porn for y'all...

Here's a couple pics of the deficiency you predicted...nice call!!

I never lift my root mass out,,I just drain the tank by turning the level column down and drain through it. Funny I have a Ripley's OG going in a waterfarm right now also.It was placed in the bucket Dec 4 as a seedling.
