The picture with the tag(unknown deficiency) shows an unknown deficiency on some leaves. The tips and edges of some leaves are dry and crispy and some have spots resembling a calcium deficiency. We have had a few hot days 35 degrees+. Just ordered a calmag sup.

This would be due to a lack of moisture. The big giveaway would the crispy, dry appearance that shows up on leaf tips first, then progresses to the entire leaf. This often happens during hot, dry weather when moisture evaporates before the plant can absorb it through the roots.

Tips yellowing Week 8 flower So We are about to hit week 8 flower and im noticing the tips of the leaves around the buds are yellow. It is just the tips of the leaves and am not quite sure why this is happening or even that it is all that important being so late in flower? Anyone else experience this?

Leaf discoloration... having a hard time deciphering it.Starting to see some leaf discoloration, possibly some spotting, and most recently noticing the tips of newer leaves looking a little burnt. Any experience growers want to point me in the right direction? Seems like it could be nute burn, or potassium deficiency?😩
