First time grower with coco and dynagro

[Bluemonkeys1991]

Yea cause each time you water it gets new oxygen and perks up then the roots are suffocating after it uses it all up. They don't actually look that bad Ive had them really droopy with probable root rot starting. You can actually see the overwatering in the leaves its all those wrinkles by the leaf veins. Its like when you're in the tub too long and your skin gets wrinkly. The folded edges are it trying to transpire more water out and the taco leaves and yellow is mag. Let them dry out and give em some mag if needed and you're good to go.

Yeah, I did notice the wrinkles in the leaves were holding moisture, but I always assumed it was from
The humidifier, but I don’t think my humidifier kicks on anymore, it usually stays above 60 percent without the humidifier turning on now, and the exhaust fan kicks on when it gets above 63%. The fan probably turns on every ten minutes or so, exhausting the humidity that I assume is being transpired out of the plant at this point.

One thing that does confuse me though, is that I’ve been watering daily since not long after sprout, and they’ve been in their 3 gallon containers for about two weeks now. Would it have taken a week and half after transplant to start drooping? I haven’t changed frequency of watering at all. My mix is 30% perlite, I don’t think I’ve mentioned that yet.

At least now you know that fertigating daily soon after sprouting is not best practices for coco.

Like others have said you are over watering. Until a plant is full established you need a certain amount of dryback before watering again. Even when plants are established you still need a certain amount of dryback. Your plants are not nearly big enough to be soaking everyday. Soaking them daily with nutes is just keeping them waterlogged and most likely dropping your medium ph below absorbable levels.

Your first feed should buffer Mn, Ca and wash put any excessive Na or K thats uneeded. I wouldn't worry about deficiencies till they are healthy...only healthy plants eat enough to worry about not having enough of this or that.

I'm afraid this isn't accurate. It is air that provide roots with oxygen.

It's both, nute water and air. Primarily air with coco. Water w dwc. Seems if the coco is oversaturated, that could impact air availability.

Your statement isn't accurate either. If water provides oxygen in dwc, then there wouldn't be a need for an air pump. It's not like the Hydrogen molecule and oxygen molecule separate from each other.
Since water and air can't occupy the same space, it's more than just 'seems coco is overstaturated.' That's actually how it is. If coco is saturated, there will be zero air exposure to the root zone.

I always read it's from the air the water pulls in as it drains out. Why else would an overwatered plant perk up when it's watered?

See, i thought that was what mixing the 30 percent perlite in was for, so that the roots could get oxygen even when the media was saturated.

Yea that doesn't always work Ive done 50% and still overwatered. It helps once roots are bigger.

Perlite adds drainage and reduces compaction but doesn’t stop it from holding too much water.

 

[polishpollack]

Soil needs to dry to put air into itself. the idea of water draining out and pulling air in is a bit of a fallacy. water and air can't exist in the same place at the same time.

Air pumps and waterfalls can increase DO. They can also induce Co2.

It's in the water.

This pot can go days without nutes. (fertigation)

This pot needs (must) have nutes multiple times daily.

I was trying to explain this to @Bluemonkeys1991 (roommate), and was trying to explain this with words boo not really my specialty Lol . We’ve both got plants around the same age in the same sized pots, the outside of mine look more like the bottom pictures but outside of his look somewhere in between. Not quite as bare as the top picture, you can see the roots but they’re not bound at all.

Right on. It's frustrating when things go funky.

Everyone should grow extras, dont treat every plant the same.
Experiment with nutes and watering, etc. Learn from side by side.

Best wishes on all grows.
