My apologies...Im growing in soil. Foxfarm to be more specific, lol

I've never mixed soil with synthetic nutes because of the complications involved with keeping the root zone happy. Synthetic nutes are usually really acidic so they "eat away" your soil buffers very quickly making pH unstable.

Also, the heavy flushing you did contributes to loss of buffering capacity and FF is peat based. Peat is naturally very acidic (like 4.0 ph) so reduced buffering capacity will crash your pH.

I can almost guarantee that you are in a lock out situation and the plant is not hungry.

At this point I'll leave it to folks more experienced in this style of growing but I would be looking at root zone pH/temp/ moisture for a solution.

I was thinking the brown spots and discoloration could be calcium deficiency so I made up a mild foiliar spray with cal-mag and hit only that plant once. Hopefully between those two changes fixes the issue, but then my issue is figuring out which one fixed it if it does in fact fix the issue

Root zone issues will cause a lockout and will look like defi. Considering no real previous issues and the recent change being the heater. Good odds on hot roots. Let us know what happens.

Thanks for input....Ive been thinking about next grow switching to a powder form of fertilizer and see if I do better with that. Up until yesterday I never noticed any problems with any part of my grow. The only recent change I made was add the heater because I am now growing in my basement which is a little cooler. I had the heater outside the tent and the hose was placed in the middle of the tent, possibly more pointed at the fabric pot of the one having the issue now. I turned it towards a wall to see if it helps disperse the heat a bit more even.

Ca is immobile. If you see signs of a deficiency on older leaves you are looking at last week's problem. Especially at this point in flower you will be chasing your tail on that one unless you're seeing problems on new growth. Not to mention that calmag is loaded with N which is not where you want to be right now.

On a side note, it's important to not only think about Ca as the "bricks" that build the plant. This critically overlooks the fact that Ca is responsible for the hormone signaling too. Too much or too little will disrupt critical pathways in flowering.

Time will tell. I hope I'm wrong and she was just hungry.

I hope so too, lol. I will just give her the whole shabang of foxfarm trio and hope it nails the issue. Its just strange that the middle one is the only one (so far) thats experiencing this issue....lol

It's not "strange" at all. It's a clue that your problem is in the root zone. The one thing that plant does not have in common with the others. Good luck and keep us posted.
