You need to flush with 6.5 water ASAP to help correct PH and remove the massive salt build up you have. With this salt build up ,every time the pot drys too much the salts burn the shit outta the roots giving you this rusty necrotic look. Flush every 4-5th feed.

It's probably just still a nute burn. Miracle grow has nutes in it as well.

And maybe over watering. try only watering every three days or more. (I'm not sure what you've been doing, but try that)

So in regards to feeding im only watering one a week and im taking just plain tap water a gallon and letting it sit till next feeding. like i said b4 i tried some nutes (Vigoro plant food 24-8-16) always heard plant needs more nitro during veg and more phos for flower... I stopped the nutes 2weeks ago after leaves started getting brown spots dry and yellow. So i just went and bought a soil ph probe and for the ph of soil it looked to be reading a 8 but the meter also only goes to 8 so i dont know if its higher! Now should i get stuff to ph water and try to balance it out or do i need to get ph of water and determine to ph up or ph down before adding to soil????

If ph is pegging scale then i would ph water to around 6 and flush the hell out of it. Remember every time you water with the mg soil your feeding. You cant over water by how much you use, but by the frequency of watering. If you just watered recently then u can try putting a small fan blowing towards the dirt to help it dry a lil quicker

If you're going to attempt to change your Ph, you want to test your Ph first. Just over water, till the pan under your plant has water in it, then test that waters Ph. Then change the Ph based on that test.

And plants need nitro during flower too. The leaves turning yellow and dying is the plant cannibalizing itself, to feet its fruits. It's sucking the nutes from those leaves, and letting them die. That's why they turn yellow.

Air circulation is always good. the less air circulation you have, the more your plant is like a asthmatic baby, the better the circulation the healthier and more "able" your plant will be to grow, and support new and old parts of itself.

No. If the plant is sucking nutes, it's not Ph, it's a nute deficiency. But yeah, once everything is balanced out it will stop sucking the nutes out of them. Some might die and fall off, but it's fine. don't worry. You can lose 1/3 of your leaves and be straight. And if it's still vegging, it'll grow new leaves and branches with the nutes it's using.

Only time will tell. First you need to get ph in check so your plant is able to use what nutes are there. Then you will know if they are lacking anything and adjust accordingly. Right now you don't know whats available to them because they're not uptaking anything due to lock out from ph being off.

Again, it might just still be nute burning. I've heard of a lot of people having that problem with Miracle grow. I used to use Miracle grow nutes, and everyone on here got crazy angry and feaked out on me saying it was plant poison.
