having trouble figuring this out

[imgrowing]

only some girls are doing this and others look great, promix hp with GH 3 part.
not over or under watered
i have gone down from aggressive feed to mild feed last few feedings, does anyone think that may cause the drooping?
20 gallon pots, and temps haven't been great so maybe cold roots?
any ideas

the light green is from bad picture

How do you know that they haven’t been over or underwatered! You can’t lift a 20 gallon pot! And if you’re in a humid area, they may take a while to dry out! I think the plants look good if you can dial in the watering! Just two cents! And you want to see light green new growth! That is a good sign!

any ideas

My idea is the same as @Oldchucky's. The light green color of the new growth and the drooping leaves indicate wet soil. Let it dry till that light green color darkens and then water it less often.

Also, is the pot sitting on the ground?

pot is on the concrete patio and in the direct sun for about 12 hrs.
my way of testing the 20 gallon pots is to stick my hand in several inches to see if dry, i also have a few moisture meters that go in the sides at different depths. and i don't water until the top is dry and the middle and bottom are on the low end of the meters.
the new growth is a lighter green but that picture exaggerates the light green.
stems aren't drooping which would mean overwatered and leaves aren't puffy either.
i really don't feel watering is the issue.
also my 1st time outside in 20 gallon pots so just learning

Right on! Sounds like you got a handle on it! You’ll figure it out!

I read your comment about being in the ground. I have several fabric potted plants sitting on ground. Is this a no no?

you generally want some air flow under the pots and also ground could be to cold.

might have figured this out.
is this not the start of light burn?
girls have been outside now for a few weeks so will be acclimated to the sun.
they were getting perkier earlier today now drooping again.
could they be saying i've had enough for the day?
the ones that get shade first seem a bit better

Maybe! Mine sit out in 100° every day! I don’t see that! But towards sunset, I see shade leaves turning their backs on the sun! You’re in a different climate probably! The relative humidity can have a big effect on a plant transpiration! And they use that transpiration to stay cool! So if you’re in a humid area, maybe the plant is heating up a little more! They don’t transpire as well in high humidity conditions! In my opinion, the enemy of the plant is not the heat! It’s the humidity! It slows everything down! From the evaporative cooling effect in the pot to the temperature of the plant! The pot runs hotter, the roots, get hotter, and the plant gets hotter! All from the humidity! Just two cents! it’s kind of a weird concept! Your plants in 85° and 70 or 80% humidity might be heating up more than my plants in 100° with 15% humidity due to the lack of transpiration! And the core temperature of your pots might even be running a little hotter than mine due to the lack of evaporation! Just kind of applying a little horse sense here! I use a lot of perlite in my medium to encourage that evaporation!

If you raise the pot up a little bit to expose to the bottom to some airflow, I think it allows for more even and complete dry back! That is a good percentage of the pots surface area that can be used to help dry the soil out deep in the pot! When you’re on the ground, you are eliminating that surface area! And the bottom third of the pot may never dry out unless you really watch your watering! But I am talking about small 30 gallon pots! The minuscule five and 10 gallon pots I’m not sure it has that huge of an effect on! But I think you’re better off getting them up a little! Just another two cents! if you think your pots are drying out too fast, you can drop them down onto the ground and they will dry out a little slower!
