First Auto Grow

Grow progressing well at this point, but preparing for a week trip away and came up with the idea to set up a drip irrigation system when I was gone (what a hassle). The problem was that I had to run directly from tap hose with elevated ph in the 7.5 to 8 ph range. Also, in climbing around pots with dripper hose and testing flow, etc.. I had several over watering scares. It worked overall, but I soaked the plants before I left and then set a 3 minute duration every 3 days when I was gone. Fear I may have over watered the plants, but the White Widows and half of other strains looked good when I returned. In 3 other plants, I started to see yellow spotting and yellowing of leaves. In these plants, spotted "the claw" and some signs of over watering or ph fluctuations. But White Widow held up nicely. Dealing with occassional white fly and put up Safer bug strips.
