So i tested the run off of a few pots from separate tables.
5.9 PH in 6.3 out
6.0 PH in 6.5 PH out
250ppm in 450ppm out
350ppm in 800ppm out

I water every 2 or 3 days by doing a lift test and finding out if they are still heavy or light.
But they are getting very light green then yellow then dead brown leafs, and some spotting various as well.

Here they are in VEG. VEG.JPG

Then about a week into flower

Then about 20 days into flower.

( I will post more pics below of leafs.)
Its like they go from healthy to shit.
I feed around 600-800 ppms I was PH at 6.2 6.3 ( but i think im gonna go back to 5.8)
Here is is how i water in Bloom I use roughly 5 gallons of water ALL TOGETHER I Mix in ( Not per gallon) 7ml of Floranova bloom, 5 ml of Flora Micro, and 5ml of Earth Juice Bloom 5ml of Mammoth P ( this is for the whole 5 gallons not that much per each gallon) My PPMS come out about 600-800. Then i dump the 5 gallons into the tray and they suck it up in about 20 - 30 minutes.
1 gallon containers, 16 per table.
They are under Quantum boards getting about 320 watts per table.

I would get a handle on my pH firstly. I don't think a pH of 5.8 is going to help you, considering what you're growing in. Once you've got this down, I would address your purple stems; unless that's genetic?

So you're filling the tray and letting the plants suck up the water through the bottom of the pots? Or maybe I misunderstand. But if that's what you've been doing you don't want to do that. You want to water from the top and remove what runs out and into the tray. But I see all the hoses so I'm confused. Which isn't uncommon. :bigjoint:

Yah the lines are all goofy some are stronger then others and it was just a pain in the ass so i ordered new connectors and dripper system but until the change i have been dumping water in letting them soak it up. But this problem existed before the top feeding or letting them absorb from the tray.

When your top watering was working did you remove the runoff from the tray? You don't want the plants to sit in the runoff. You'll end up with buildup in the grow media. What you want to do is drain to waste.

What should the PH be for Pro Mix ?

I believe your nutrient mix should be around 6.3
Are those 6 inch pots? or 1 gallon?
Is that top feed drip?
Whats the light source?
How is your water temp?
Do you think 250-300ppm is light feeding for flowering?
 
Your nutes are pretty weak. If you feed every watering it might be ok but you only have 1 mg/ gal of micro. You would have been better off using Lucas formula and feeding every other watering.

1 gallon
Top feed drip but not currently being used.
Light source is HLG 288 3500k boards 320 watts
have a water heater water is 68 F
I dont feed at 250 -300 i only used that for the two pots i tested the run off

Okay, so 600- 800 every other watering ? I feed at 600-800 every water so every 3 days approx ? am i cooking these things ?
 
I don't know anything about earth juice or mammoth P but I hope they have some micros in them and at least a little bit of N. Your plants look hungry so your 600-800 ppm's must be out of balance.
