Newbie needs help please....

Hey everyone,
I’ve read numerous posts on this forum and am more confused than ever. My plant seems to have a magnesium deficiency week one into flower. I am in 7 gal geo pot with subs super in bottom 40% topped with mix of coast of Maine stonington and happy frog blend. I run water through small boy to dechlorinate. I added 2 tsp roots bloom terp tea to base so far. I also did a watering using slf-100 to see if it helped. Only other additives I’ve added to water are mammoth p every other watering and suite leaf cal mag. Today I ph’d my water to 6.5 before watering and tested runoff. It came out at 7.1. Any suggestions are appreciated.

If this were my plant, I would flush it hard with PH'd water, let it dry out, start feeding it 1/2 strength base nutes like Floranova 4-8-7 and skip all the other stuff for now. Reset. It works.

It needs mag so give it some epsom.
You can even do a foliar for quicker results.

PH testing runoff in organic soil isn't going to give a true reading. You're better off getting a kit and making a slurry with distilled water, then testing that.

Thank you for the advice

She just needs a little Mg as noted above, otherwise, nice girl.

Thank you. See I thought the supersoil mix alleviated the need for a bite line? I’m planning on brewing a roots bloom tea say third week of flower or so for a boost. I understand mg is a common deficiency. I will foliar the mg today. Do u need to ph your foliar?

*nute line not bite

I might spray them once with Epsom, but being you're in flower, I wouldn't do much more than that. Just add the Epsom Salts to your feed regimen and you should be good to go.

On the whole plant looks great. Good job
