need help figuring out a weird issue I'm running into

[insaneperson215]

so I just fed my plants a week ago used a 3part solution then now 2 days ago it looked liked a nurturance issues so i checked the ph. to see if it was locking out and i was right it was acidic so I fixed it now so i checked the ph again and it was acidic so i need help figuring out what's causing the ph. to lower

Are you growing in soil and indoors (venturing a guess here)? If so, are you checking the pH of your liquid mixture every time you water or feed the plant? I personally shoot for a pH of 6.0 to 6.5. I don't see how the pH could drop even lower than that in a potted plant without some input from the grower. I am also wondering if the readings you are concerned about are coming from the soil, or what?

If you're doing hydroponics or something, I wouldn't have a clue about it. And, apologies for the misunderstanding.

What did you do to fix? I am having a similar issue with my auto flowers

just by using a ph. up and down solution kit but im hydroponics so for soil i think you just water when needed with dechlorinated water ph between 5.8 and 6.7

I have been watering in at 6.2-6.8, noticed my first brown spot at day 7 from sprouting, was using just plain RO water as a seedling, i then started full strength calmag, then i stopped with RO entirely and just use aged plain ph'd tap water(comes out at 350ppm). Day 30 now and i cant stop the brown spots

Got a pic?

I have been plucking the bad leaves off, seems like the old growth seems to be affected, i left a couple leaves on with it, best picture i have at the moment, i do have older pictures

No problemo. I did not realize you got back to me on this. That's too bad about your monitor. I had a display out on me a few months ago. I am really glad your plant rebounded though.

The cal mag is what did it to you. When you feed cal-mag you need to keep it in balance with other nutes so by adding cal mag alone you locked out your other nutrients. Always feed in balance

I am now doing 1/4 strength nutes with tap water( would should be balanced, but keeps spreading). I read something about rust fungus on one of these forums, i have been trying a foliar optic spray ( overgrow, has a small percentage of copper and sulfur). But the brown keeps spreading.

I am very sorry for steeling this thread, i just recent plucked the bad leaves off yesterday, this happened over night lights on, which is usually how it starts, gets progressively worse. Its hard for me to capture it on camera, and appears more noticeable with lights on
