Hi all! I'm currently growing indoors. 4x4, AC Infinity S44 Ionboard 400-watt LED grow light, AC Infinity 4 inch Cloudline exhaust system, growing in Promix HP, watering with tap water at 6.5 PH, using Homegrown Cannabis Co's basic nutrient package. 77 degrees with 75% humidity. Growing 5 plants in 5 gal. fabric pots. Started noticing some yellowing between the veins. Is this the start of a magnesium deficiency or am I making a big deal out of nothing??
