I've been growing for some time now. Generally, with great success. However, in my last couple of grows, I've had issues with some of my plants. I noticed that while treating different plants with exactly the same the formula of hydration, fertilizer, light, etc., some have shown issues of discoloring, drying, and dying leaves while other plant next to them (overlapping actually) are very robust. So, now I'm wondering if the quality of the seeds has some significant impact. I had been paying a good price to get seeds from overseas without problems. But, because of price, I changed to a stateside supplier and now have connected the dots that these plants have been more problematic. What do you folks think??
