Hello all! I am a long time lurker, but a first time grower and poster. This is my first grow they are Pyramid's auto Northern Lights. They are both exactly a week old. I am growing them in my closet with 5 cfls each 3 2700k and 2 6500k 23 watt. The lights are about 3 inches away from each sprout, they used to be about 1 inch away until I noticed the leaves curling and moved then farther away. I also have two fans in my closet and consistently monitor the ambient temps and humidity. I used the hand method to test the radiant heat from my lights and they feel fine. I also have not added any nutrients other than about a half a tablespoon of blood meal to each last night. Today i noticed a light discoloration on the bigger sprout's new leaves. Now here's the tricky part, I received my ph meter in the mail today and i measured the runoff ph to learn that it was about 7.5. I have been using tap water and measured my tap to learn that it was sitting around 7.8 - 8.2. Should I use distilled water instead? I plan on using fox farm grow big for one feed and big bloom at the first sign of pistils. Should I rethink my nutes? Has my high ph level or blood meal caused the discoloration? Thank you to any and all help i can get!
