Chow_13answered grow question 3 years ago Never seen leaves swollen like that. If I had to guess it would be a combination of over watering and heat stress.
Whats your grow conditions. Day/Night temps, humidity, How often do you water. Never herd of SWA SuperSoil. Is this the source of nuturents or are you adding any. Whats the PH of the soil, runoff. whats the EC of your runoff. A diary would be a lot of help.
