Mephisto-Walter White (2nd Time)

Week #1-Mar 25 to Mar 31 3/25-Sprout fully emerges this morning. Looks good. Keeping the tent moist and warm and covering the sprout with glass beaker to keep moisture in. 3/28-Leaves were getting yellow in the middle so I checked the Ph on runoff and it was way high. Not sure how that happened but I'm theorizing that the water I had put in the sprayer got contaminated somehow and Ph went way high. So I decided to water the pot to runoff with a new batch of water without the sprayer at 6.0 ph and around 400 ppm. Will monitor reaction. 3/29-Seedling appears to be getting a little more green and I think she's going to be ok in a couple of days. 3/30-Seedling returning to form. 3/31-End of first week and our little seedling is all green again and looking healthy as we go to week #2. Compared to my first WW grow she actually looks a bit further along after 7 days.
