I'm growing 3 week old autos in Promix HP. 5 gallon fabric pots, Ac Infinity s44 Ionboard LED light, 4x4 tent, and using Homegrown Cannabis Co's standard nute pack. After reading the feed chart wrong, I accidentally gave them a double dose of the seedling booster. After realizing what I did, I took ppm readings from the runoff. I had readings in all 5 plants of 1,100 to 1,600 ppm. I did a flush and got them down to 300-320 ppm. They came out of their funk just fine and they are starting to show signs of needing fed. My problem is that a dog knocked over my cup that had my PH meter(cheap ass yellow one) soaking in probe storage solution. I live in a smaller town and you won't find anyone that sells them here. The probe got water inside and is being dried. I already ordered a much better probe to replace it. My girls are still wanting fed and I'm afraid to go ahead without the ph meter. I know as a fact that 5 ml of ph down will bring 1 gallon of my water in range, but not sure what the nutes will do ph wise. My new meter will be here Monday, but my plants are starting to lighten between the veins slightly. Should I go ahead and feed them, not knowing what the ph of the nutrients will be, or wait 5 days until my new meter shows up??
