Diagnose these deficiencies for me please

These are all from different plants in the same grow . I over watered and started seeing signs of lack of chlorophyll and light droopy leaves, slowed growth, delay in flowering. And then these deficiencies started to come forth . Looks like a bit of every kind of deficiency to me but I'll let y'all in with what is coming through most. Looks like a lot of potassium and phosphorus deficiency I think and calcium and magnesium. But i want to hear others opinions too. And once the soil dries and roots recover , will they start uptaking the nutrients again without adding More to the soil . There should be plenty of nutes In the soil from before the plants stopped uptaking nutes shouldn't there? Opinions desired. Thanks

To me, all of leaf pics look like the grower is watering their plants to frequently. And if you continually do that, most-times you will end up with what looks like a mag deficiency on many of the leaves that are yellowing, but it's just a false positive! Saturate them, let them dry out before watering them again, saturate them, let them dry out before watering them again, etc, etc!

What size are those pots and what medium?

I made the pots myself out of insect screen which you find on Windows or security doors. The black plastic 2.5gal pots had very poor drainageand they simply wouldn't dry up. Plus a little bit to much water with watering. 4 days after changing pots to breathable DIY pots there are new white roots coming out the bottoms and sides of the mesh in replacement of the roots that died off on the way to recovery . The deficiencies are just from a lack of air to the roots. The soil is fine and the nutes are good . Just need to wait out the recovery now

With all your YouTube watching and professional grower tips you’ve received in the month you’ve been growing shouldn’t you be able to figure this easy shit out?

Plastic pots should drain fine if you are using decently aerated medium and the plants metabolism and feed is in sync. I'm running plastic and fabric pots (2 of each this round), all 3 gal, and the plastic pots actually run-off faster than the fabric pots with the same medium and same amount of feed. A lot of ready made cheap potting mixes have wetting agents, water crystals, slow release nutrients and a bunch of stuff that's not really beneficial for growing weed. A pot refusing to dry up can also be a sign of lockout and stunted metabolism, not always medium with unenthusiastic drainage.

You should be able to hear and watch a well aerated soil-less medium drain excess water as you apply, but organic soils are a bit different in that regard.

A good peat, compost and perlite mix (1:1:1 or 2:2:1)will drain well even in plastic pots, and cost next to nothing to make yourself. I have had nothing but bad luck with potting mix such as Searles from chain stores when it comes to the ph buffer, or lack of, normally leading to acidic medium.

Wasn't meant to get so off track, but having to make pots out of flyscreen might be a sign the medium needs more aeration in general.

And yes I did figure it out all on my own and it wasn't a lack of nutrients, or an abundance and cock heads like you don't get to know why or how I worked it out hahahaha
