Hey hydro growers I need a little help please. Every time a plant gets close to harvest the leaves turning yellow and start dying. I have been using Masterblend @ 2.4,1.2,2.4, Big Bud, Overdrive, TPS Bloom, Flourish Cal +, Garden Friendly Fungicide, Neem Oil, and Miracle Grow not time released... Using 3 1000w equivalent leds, 2 650w Equivalent leds all High PAR..It does get warm in the grower room but the lights are between 12 and 24in from canopy.. Flowering under 12/12, Veg 18/6... any ideas?? Pics at bottom...
