I screwed up a bit and stressed my ladies. I decided I should do a Sledgehammer flush to clean up the fabric pots. Then, the next feed, since I had just run out of the FF trio, I decided to use the GH stuff that I had purchased for an indoor grow. (Which I’m not going to do now.) The result? A lot of yellow, dying bottom leaves. I thought “wow, that flush didn’t turn out too well!”
Of course not. I forgot to pH the GH feed! The next GH feed, I measured and the pH was . . . 4.0! So basically I took residual nutrients out of the soil with a flush and then locked the soil down so my ladies couldn’t get any nutes! Ouch!
Got it corrected now. Man. I hate doing stooopid stuff! Calls for a song:
One thing kind of strange with the pH up and down I have. My tap water is at 8.0; to get a gallon down to 6.5, I have to put just a very small portion of a single pipette. But to go up from 4.0 to 6.5 . . . 9 full pipettes!
