Outdoor grow first time

Hi guys
Growing outdoors 4 plants
3 seem healthy but one is in definite trouble see pictures
They are in 7 gallon pots
In foxfarm potting soil .
Black DOG strain
It doesn't look like heat stress as all 4 are next to each other and 3 are fine
I'm thinking magnesium deficiency?
Any thoughts/other theory

Thanks

Hey @Vpark :)
Let this girl dry out much more than the others for a few watering cycles it looks like she wants a dryer medium, there may also be some root damage caused by warm and wet conditions so now you need to restark/kickstart root growth by making them work and grow and search out liquid. Using some dilute liquid seaweed on this plant would also help her recover.
The three other girls are looking nice! Good luck and keep us posted đź‘Ť

Hi Guys/girls

so unfortunately this girl died.

I started seeing similar symptoms on the other three, I also noticed that there were signs on the leaves that looked like spider mites bites .
I treated them with insecticidal soap and looks like the problem is under control.
Judging by the picture do you think tacoing leaves can be caused by pests?

there are also some black spots on the new growth only that leads to deformed leaves when they open (sorry no picture) I'll post later
Could it be mold? or some sort of pest

Hey @Vpark, this tacoing you're seeing is a transpiration issue generally triggered by high temps and low humidity, the leaf is attempting to reduce the surface area to reduce transpiration.

This issue sounds a lot like pests but post up some pics ideally with some magnification and we'll get to the bottom of it!

This is a hard one to diagnose, the obvious answers you'll get online are p deficiency, or a micro nutrient deficiency (bromine? magnesium?) as it is only affecting the newest growth. Some would say it's 'sooty mold' but it doesn't look like it as the coloration is within the leaf itself and not on the surface.
The interesting thing is that whatever you're experiencing seems to be primarily observed in outdoor grows which hints at either a pest or pathogen as the likely cause.
Spray for pests with neem, water with organic seaweed (this helps resistance against pests/pathogens and stress) hopefully in a couple of weeks you'll observe some positive changes. Please keep us posted this is an interesting one and I'd love to help you get to the bottom of it!

I think you're right the ph could come up a bit to the mid 6's and that should hopefully get things moving in the right direction again.
If you want hassle free harvests consider making a super soil with mycorrhizae on your next run, it's a lot easier than using bottled nutrients and in a well balanced mix you don't have to worry about ph management just add water through to harvest.
