Feeding question

agree with MistaOC, What does she look like? Without pics can't tell if she is already being burned. The soil I use doesn't require any feeding until 3-4 weeks. Defiantly seems like a strong blend for early stages of growth. I don't like trying to be fancy with my soil and guessing what her needs are, by then she is already stressed, showing signs of a deficiency or toxicity. If it's true that this soil last 60 days I wouldn't be using it. That takes the plant a few weeks into flower and her nutrients should have been switched at start of flower. Just an example, with your 10-4-4 ratio you mention, that should be 2-8-4 at flower. Do a TDS reading and see how potent the soil is. It only needs to be around 700-900 TDS at this young age.

In my opinion, this could lead to a completely different problem. Using such a heavily fertilized soil during the seedling stage can result in your plants getting too much too early, potentially causing nutrient burn. If the plants survive, you’ll have to wait and see whether the fertilizer—or the soil—actually lives up to its promise. You’ll know it’s running out when the lower leaves start turning yellow.
