Leaf issue
What seems to be the issue with older and new leaf growth here? It looks like cal-mag or potassium deficiency in my opinion, but I’m not really sure.

About 40% of leaf tips show burn, 5 days after last feeding (Biobizz schedule, but 3× stronger than previous one). Medium: Biobizz Lightmix. DLI 47 center / 38 corners. Day 31 (autoflower, early flower). Temp 22-27C, 55-62% RH. Feeding today—should I lower nutes or any advice?

Leafs with brown spots
The leafs on my plant are showing brown spots. Could be nutrient burn or nutrient lockout? Not sure at this point. It started a week after blooming.

Yellow leaves
Hi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?

Some leaves are showing small burnt spots and slight curling. what could be? I'm currently dealing with Fungus Gnats in the grow. I applied Beauveria and covered the soil with burnt rice husk. I’ll wait for the soil to dry and then use hydrogen peroxide to try eliminate the eggs.

Nute Burn or Calcium deficiency?
Hey, I’ve just joined the website and already looking forward to making a dairy for my current auto grow. I have 1 auto, Barney's Tangerine Dream that Ive trained to fill my tent. I seem to be experiencing possible nute burn, would anyone agree? Or is it a calcium deficiency?
