Droopy plant

[SamsonsRiddle]

I'm using canna profesional plus soil.

dude, that shit is made of peat moss and tree bark. i used promix which is peat moss and perlite - and it liked to go from wet to damp. i watered with nutrients every day once roots were established in fabric pots. They were only 2 gallons, so adjust accordingly.

if you keep underwatering you will start to notice deficiencies, a wide rainbow of colored deficiencies.

I had the same problem with airpots . Water tends to run through and out the sides without uniformly wetting the entire soil mass. This leaves pockets of very dry soil and root stress and death. Once I started super saturating the soil/ root mass the drooping stopped

I am getting some conflicting advice here so now I don't know which to follow...on the one hand I should super saturate the soil and on the other I should water less but more frequently...

Conflicting advice is pretty normal on the forums, everyone has an opinion. You just gotta make a choice on whose advice to follow.

It's a shame those pots don't allow you to check the roots without fucking them up. That's the only way you could see for yourself what's going on with your roots.

It could be another issue completely. It could be you are watering just fine now but either over or underwatered sometime previously so the root system is not developed enough to maintain the size of plants under that intensity of light. One little test you might try is to take one of them out from under the light and off to the side for a day, and see if the same thing happens to that one. My bet is it won't droop. I've had this same problem before.

If you are over watering, the stems stay up and the leaves bend over at the stem tip.

If you are under watering, the stems bend with the leaves.

The point of good distribution of water is critical. When you water apply it very slowly and distribute it evenly all around the surface. Maybe even let it sit a bit so that the wet bulb (wetted area) opens up via wicking. A good watering can is priceless.

This is why it is so important to learn how to irrigate. You want to irrigate one time heavy until the water runs out the bottom and quite a bit at that. The second irrigation is something much less just enough to wet the cap of the soil unless of course you feel it down deep drying out quickly.... the third irrigation a bit more and then the fourth or fifth irrigation do your heavy watering again. Unless you are in a super porous medium, this is the way you should water.

When plants get to the adult stage,their water uptake is huge, but each hybrid soil or mix has a specific water retention capacity that ideally is calculated and then taken into consideration. It is good to test the point of enough dryness to see the plant ask for water. Learn that point. Make them ask for water when they are adults and even youngsters. Don't make them droop completely. Always leave one plant with less water so you can gauge what will happen if you use less water if you can....

You can also see when roots are sitting in water for a prolonged time, the bottom stems will be up and the leaves bent down, yet the stems and leaves above are both standing up.

Now with all that said, if your EC is high and there is not enough Ca, you will see your plants looking for water much more often and maybe even seesome burn from letting them ask for water..... which will make everyone scream at me....

This really is a science.
