Hey ya’ll. Glad to be here. New at growing and Ive run into a jam. Been growing Autoflowers, day 16 and ran into a yellowing issue. Water and soil are correct PH, using a 1000W led in a 2*2. Thought it might be cal mag deficiency and used foliar spray today. Growth seems to be coming along. Seeds are NL from FastBudz. Any assistance would be appreciated.
