My growing medium was measured with an electronic ph tester (probe with two dissimilar metal prongs stuck in the wet potting soil overnight it tested slightly acidic at ~ ph 6.7-6.8. I took them straight from the 1" seedling array into one gallon pots. I thought maybe since they are on 24/7 they were dying to produce some chlorophyll which , I gather, happens during the night? Also I should mention that I have been until now using (Shudder) Tap water of the same ph. should I start the bud cycle? don't want to cut myself short in yield. Do youthink I overdid it with the lighting? at firsty i had them very close <1" but have moved them away to 6-8" and the new growth seems happier. What kind of fertilizer? High nitrate for veg growth or mixed all around type? Need a way to water them for a week while I'm gone for the holidays. Ideas? And Thank you for your reply very much.
