Looks like nutrient burn. She’s a little high in nitrogen. Water feed for a few days and convert to a bloom tea for the week.

Lack of water or its something else.
Did it burn from nutrients, or was it due to a lack of phosphorus, or just because it didn't have water?. It seems to me that it is due to a lack of water, but a lack of phosphorus also occurs in a similar way.😄

Yellow leaves near the harvest
This would be my last week of fertilizer watering. And the plant has the leaves turned to the side and with yellow spots. Sign of lack of zinc? I would start making the flush from Friday, is it recommended to start now? In about 2 weeks I will harvest (I tried to water today)

Deficiency
Spotted a deficiency on my AK 420 Checked on growweedeasy charts and Imo it's a cal/mag deficiency. I meticulously check Ph and runoff and she had the same treatment as my royal dwarf. Probably more hungry than the others. Just wanted to make sure, cal/mag deficiency right?
