I have a lot of ILGM plants now and they all do the same thing to me…
The leaves start yellowing and dying when the plants go into flower. The are green as can be until they flower.
Here is the 4-week progression of flowering of these Autoflowers:
4X2 SF2000 LED
MG Potting Mix and Espoma Organic Potting Soil
About 30% Perlite
Espoma Organic Plant-Tone All Purpose Dry Granular
Espoma Tomato-Tone Organic Fertilizer
Water pH 6.5-6.6
I mix dry fertilizer in the soil when planting, then I give about 1cup/ month topdress. The first topress is as soon as they show pistils. The plants are green and healthy until they start flowering. Then, all the leaves slowly yellow and die, including sugar leaves. Every strain of my 8 autoflower strains.
I do battle a little powdery mildew but spray with organic fungicide once or twice during veg. The green plant in there was also sprayed. They Akzo do this if not sprayed. There are some fungus gnats being stuck to traps, they don’t seem too bad.
Any suggestions? Thank you!
