I have two autos in early flowering and just tested my PH for the first time. Yes…I’m new. The reading from the plants in Miracle Gro is way too low. It’s sitting around 4.5 according to the color charts. The plant looks well but I’m concerned I’ll end up with airy buds or hermis.
I have General Hydroponics PH kit. My question is how best to raise the PH? Should I flush until the run off is raised or attempt to raise it gradually over time? I’m in 3 gallon pots and ran 2 gallons of tap water PH7 through. I then ran a gallon with the PH raised to 8 and the run off was still too low. Sorry I don’t have a pen.
Any suggestions would be greatly appreciated!
