I noticed this morning that the upper leaves on my largest plant are canoeing upward. Can someone help me figure out what this is? I believe the plants may need more nitrogen, due to the yellowing of the bottom leaves on my larger plants and a yellow spotting on one upper leaf. This is my first grow as I havent had my card long. Help? :c
Temp and humidity? IMO canoeing is from environment not feed....... Sent from my iPad using Grasscity Forum
Pictures would help diagnosis. Canoe shape of the the leaves indicates heat stress. Plants do this to expel water. Whats your temp? What lighting are you using and how close are they to the canopy?
