Dear Community,
I would appreciate if you could help me out here (pictures attached). There is discoloration of the leaves, black spots appearing, leaf tips discoloring, and some are yellowing, drying out and falling. The top leaves are cupping upwards.
What is happening? I faced the same issue before in my earlier grow, and that negatively affected the yield and quality of my buds .. I just don’t know what’s the problem. In both instances, the veg phase was beautiful and vibrant, but once I enter into flowering, these issues appear.
Some info:
I growing Autos in generic potting soil. I am using General Hydroponics nutes (following Autos feeding guidelines by the book)
Humidity is controlled between 50 to 60%
Average temperature is around 25 Celcius
I water and feed at about 6.5 to 7.0 PH. Two days ago I measured the runoff PH, and it was 5.6
I am entering my 7th week now, and will harvest in about 2-3 weeks from now.
Light is around 500-1000 PPFD (I am using a PAR meter)
Wind circulation is ok. I have a small fan at the bottom, and a large fan at the top pointed at the lights to cool the LED’s and provide little circulation.
