38 Days from seedling. Lower fan leaves started showing what looked like very light rust and new growth yellow. Was in a 1 gallon with a 50/50 mix ocean and happy. Just moved (right before pics) to a 5 with ocean and a little worm castings. Only watered when light. Grow light at 24". Last few watering have not been PH'd due to a faulty pen, looking to get a new one over the weekend. Could this just be a PH issue? Thank you for any input. Strain is White Widow.
