Guys, I have checked online and have tried many things to try to help my plants. No matter what I do the problem still persists. I am using LED in an indoor grow tent. The temperature is around 75 and the humidity between 40-55%. I have tried flushing, fertilizing, adjusting water Ph. The problem happens for even my small plants up to my flowering. Any input anyone has would be greatly appreciated.

"M" is correct ...and "The temperature is around 75 and the humidity between 40-55%" is incorrect, the red is lockout (K) too cold at night with serious (Mg) def..flush and flush on the last flush add 2 teaspoons of Epsom salts(cal mag) to the last flush, no nutes for a week or until you see an improvement, even then 50% less, keep a bowl of water in the grow space to raise the Rh.
Overwatering will cause this as well. "Multiple nutrient lock out" is caused by anaerobic soil conditions.
