Calcium deficency but not resolving

[blueberrymilkshake]

young plants in hydro can be full of shit, they harden off over time as long as you don;t get things too wrong.

I needed to hear this :')

I was going to say the same there. DWG/rDWC grower here. Similar things happen to me with my first couple leaves, almost every grow. I get a little nute burn, some odd micro deficiencies, etc. Usually within a week or so they're fine. I think it also has to do with when you start your feedings. Rule of thumb is like two weeks, i usually start at 1 week and i get minor burns.

Got these plants growing with 1,5ml ghe gro, 1ml micro and 0,7ml of Bloom per liter, 4/5 days ago i noticed some calcium deficiency so I bought some calmag by advanced nutrients, added 1ml per liter but the Cooper spots are still expanding what can i do?

What I think your experiencing is necrosis and chlorosis from what my best guess would be from a pathogen or biotic stress in the water.

the plant in coco could probably just use some 5.8 and a little more love on the nitrogen side of things. they all look like they could use some nitrogen but go up slowly.

the smaller starter Leafs tend to discolor dry up and fall off after the older growth develops.

I don't believe you can over water coco when you're past the seedling stage.

About 3 weeks old it's been fed daily from clone, imo some not all coco benefits from a bit of perlite for the earlier stages of growth some coco doesn't need it.

your not wrong.

Ok but with a little bit of experience one can recognize a plant whose roots can't breath properly and clearly show signs of overwatering, like drooping for example

Some cocos also contains impurities like sand or sea-salt which aggravate the situation

Then, I've done extensive tests with both BB Cocos & coco bricks and found out how alot of bro'science is being propagandized by the industry or MJ superstars
like keep cocos between 90-100% moist!


Brick cocos germ rate 0/10

It drowns the roots. The acclaimed 30% retained oxygen is A MYTH.
Large plants may be cope with such a hostile environment but still I see neither a need for this nor how roots are fundamentally different...

These are the ladies now, growing gergous, topped Them Yesterday the two that had root rot getting Better

You can't really generalize about coco when each brand varies drastically in coarseness. People who stick with one brand have one experience and say you MUST have perlite, other brands have a higher air/water ratio and gain no benefit from perlite at all. Some coco with a fine consistency behaves much more like peat and requires a wet/dry cycle in the seedling stage while others can be fertigated daily from day one. Once roots fill up the container, there isn't much functional difference between them.

I think he's saying your pH isn't correct.

I'm glad he used gigantic red letters. It alerts the OP that the correct prognosis has been given.

A blue circle around the red letters would be a nice touch.
