They got 1/4 tsp of the planticilin, bio-grow, and the bio-bloom in a half gallon of water for a week when they were two weeks old. The next week, all of them at 1/4 tsp with 1/2 gal of h2o. But that is also the week I mixed in the ph up. I flushed after seeing all of them start to yellow and immediatly jumped on here to find the source. Any ideas on when to start back on nutes and should I get diff nutes?
