Hey! It's either that or nutrient burn. I says you're not using any nutrients if that's the case raise your lights a bit. Make sure when you do foliar spray it's right before lights out or tha water on the leafs can cause then to burn with the light. Hope this helped! Good luck and happy growing!

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅 Same issue still applies for now. I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍 Open to all observations.

Discoloration and Spots I'm still not sure if this is a deficiency or some sort of burn. It's definitely spreading a bit more, and I'm unsure if there's time left to address it in the grow. Video of full plant in week.

2 Yellowing Fan Leaves I have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges. It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant. From research, it could be the bump in nutes or water issue. Any ideas?

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??
