Is this Runtz Auto in Flower

[Space82]

Yes. I would say a little over a week into flowering, they should be on bloom nutrients if not already

Yes, 3ml cal mag, 10 ml Tiger Bloom, 15 ml Big Blooms, 1/4 tsp mycorrhizae, per one gallon of water, solution pH is 6.2.
With fox farm nutrition, I've gotta dial back on starting at 1/4 working towards 1/2 of recommended strength, as FF is pretty harsh .
I use FF Happy Frog and Ocean Forest medium as well
Basically I'm Fox Farm all the way

What week of flower is this 3? She’s doing good

Week 2 Day 3 bloom stage

This is a 150 watt . I'm 12 " above both canopies. They're getting like 850 ppfd. That's about customary. So lower my dial, to what 90% or 80%. That would give them roughly 600 ppfd which may flower but larfy buds would be my results.
Do I need to increase cal mag? I'm at 2.5ml per gallon ( bush doc).
And my p and k yes should be increased.
Any advice is welcome bro, thank you In advance!

All right, not all strains are the same dude some really hate lots of light others can take as much as you can throw out
My lamps in flower are nowhere near 12 inches close to any plant at any time
And I finished most of my runs at about 70 to 75% output PPFD you know it can be a great help sometimes but you can’t just follow metrics like that and expect every plant to react the same dude there’s no cookie-cutter approach to this shit so you have to learn to see what the pre-cursor are in some of these things that present themselves during the plants lifecycle once you get your eye trained to it you can see the stuff coming from a mile away and adjust ahead of time but just to let you know I’ve finished some of my runs at like 50% output on my lamps with 36 inches between my lamp and my canopy. A lot of that stuff that they have on the boxes that they sent you is pretty much garbage and as far as the mag situation goes, you might want to lean away from the cow mag and just go with magnesium, but once you actually get into the later, part of flower with an auto, the mag demand will stop altogether, but in the beginning of flower until about week four they can still pull magnesium out of the medium depleting it almost completely and that’s when you see the interveinal chlorosis on your leaves the way that you do.
So Epsom salts as a supplement with your flower nutrients
Some examples.
Sometimes less is more Homie

So in your case with your lamp settings, just upping your magnesium isn’t gonna cure the problem just to let you know the leaves that have discoloration are gonna stay that way all the way through a tall harvest most likely what you’re trying to do now is to stop any more stress from happening and just upping magnesium isn’t gonna do that when the lights are the problem you feel me so I would adjust your lights up and turn them down about 15% and see if they stop hiding from the lamp because of the way that your leaves are curling down at the same time or laying down is also telling me that the light is too intense and they’re trying to lessen the amount of leaf space available to It

Thank you , very much, for your input.
And for making it make sense as well.
I have Grown weed off n on for years, barley getting by honestly.
Now I'm home and settled and wanna really learn this the right way.
I've grown outside always, so out door is my gig, so this creating your perfect environment is new, but it's also fun to learn this stuff.
I dialed back to 75% output.
I lowered my smaller tree down another 8 inches.
Let's see how they reply to that adjustment before I fine tune.
I appreciate you
