So missed a lot of weeks in between here and now as life got busy, its ok, shit happens. Gotta focus on the real world and no so much diaries on a site for free... Plants are doing well. had a bit of a issue with some PH in the medium, it got out of wack, or something in the fertilizer reacting with something in the sprayer chamber, noticed before when adding the nutrient solution into the sprayer there was some steam/mist/vapour coming off of it. During this I accidentally over used PH down and then used some PH up to fix it, but I think it did not like this. The result was some leaf burning on all the plants, it did not like that. So now I know to toss it out and start again if I can. I also bleached out the sprayer at beginning but thought I rinsed out all the remaining bleach, even ran a Vit C through it as it will neutralize bleach but I might have missed the lip of the sprayer or part of its manual air pump handle mechanism. Also noticed I was underfeeding them a fair bit in veg weeks, was so scared of stressing them out into early flower it happened anyway. I increase feeding to aorund 700ppm on my pen or aorund 1.4EC, ideally I'll stay at 1.2-1.4 EC for the rest of the grow unless they showing they really want more. The runoff has been stable on PH and about 200PPM different from whats going in, meaning they are eating when I am giving them and they may want more. at least some of them. I have a feeling a small amount of burn will happen on the smaller ones at 1.4EC. Well see how it goes.
