What size pots? 2 gallon(7.5l) Smart Pots
Any bugs? Look real close. NO
Any other pertinent info?

Me being a big dummy, I didn't realize the runoff was what mattered most until about 2-3 weeks ago. In the beginning, I would pH my water to 6.6 or whatever and be like "hell yeah, that's easy". But then I started having the problems and found out fast I was doing it wrong the whole time LMAO

Well now my pH is completely in check but this one plant has never looked worse. Only thing I can think of at this point is a really good flush. You can't really see it in the pics but the underneath is still nice and green(most of it).

Let me explain my watering method with the Smart Pots: I water it all around the top of the soil until the water sinks in a little. Then, I hold the pot at an angle so I can pour water in and it kinda spreads out and sinks straight down(on an angle lol) then spin the pot around a little and repeat. They usually only take about a half gallon(couple liters maybe). So then, all that water drains out in to a reservoir. I then hold the pot at an angle again, only this time its runoff is being collected in a shotglass to test. 1 or 2 ounces(30-60ml) at most will come out doing it this way. I feel really good about the measurements I'm getting with a Hanna Checker(i think it's called). It's the red one with a long pen attached to the bottom and cost about $40US.

So, might a flush set me straight on this? Someone please say YES!!
:wave:

Another question. I watered last night with nutes. If it does need to be flushed would it be OK to do it now or should I wait til it dries a bit? After flushing, should I add nutes to the last gallon going through it?

Thanks for your help!

Some times it can look like a nute burn because the ph is off. I wAs told that if the ph is over 7 less than 40% of iron is available to your plant. To keep your ph lower you can get this stuff called earth juice natural down. It works wonders. Plus if your gonna do indoor soil go organic, fox farm isant even omri listed. Good luck!!!

Happy growen

The last 4 waterings have all had 6.3-6.6pH runoff so I know that's not the problem. It has to be in need of flushing. I ran 4 gallons of water through it this morning so hopefully it will start to improve in the next day or two.
