the lower leaves of my plant are turning yellow & starting from the edges of the leaf I’m thinking it’s magnesium or potassium deficiency? Idk someone can stir me the right way

You have slightly burnt tips so nute burn,and yellowing N defiecency.what week of flowering u at??
 
Tell me about your soil, nutes, and feed schedule so we can figure out if this it's def or lockout.... Do you water until there's good runoff?
 
I’m using miracle grow for soil , fox farm nutrients & cal mag. I feed once a week I always do half of the recommended dosage on the chart.. my last flush was about 3 weeks ago I had nutrient lock it was bad & it’s bounced back. I always water until there’s a good amount of runoff

Which MG soil is it? Is it the MG moisture control or something?

Ok, it's unlikely you've had lockout now or before. Before waterings make sure your soil is dry enough to you need water, I suspect your roots could use more oxygen. And add potassium, I'm sure one of your bottles has a good portion in it, ease up on the N a bit too. The stage your plant is in, it had shifted focus on needs for nutrients, less N more PK

Ok I’ll feed it some pk, I’m going to Home Depot to get molasses to add it to the feeding.. if there’s anything else you see wrong with the plant let me know.. this is my first grow

Your not doing bad. Be careful adding molasses every feeding, read up on it a little and you'll understand.
 
You're definitely looking at a potassium deficiency. You're approaching the start of mid-flower...most vigorous growth upcoming, potassium is in its highest need for these next couple weeks. As was said, you can ease back a bit on the nitrogen...not completely, and start upping the potassium and phosphorus to keep them balanced. Becareful with molasses as not only is it very high in potassium, but also in iron. If adding too much or too often, it can create its own problems. Molasses is best used near the end of the cycle when the plant stops/slows down in giving sugars back to the soil.
 
Thanks guys I appreciate everyone’s response & help I fed it some potassium & phosphorus today. If anything else pops up I’ll update this thread. & yeah you’re right I couldn’t find some molasses at hd but I did get some other stuff, I also want to add I updated my weekly video grow journal so if you guys want to have a look feel free too watch. Thanks again for the tips

Nice video, just 1 thing, at 2:50....'they don't really like that shit'! lol :) Don't make it a habit to spray your plants all over with lights on them, that practice will get you in trouble at some point!
