Hey guys! I'm a new grower this is my first grow and this here is my bubba kush. It's been a tax bit slower the my white widow but that's to be expected. So no worries there. And I plan on posting newer pics tonight. So my set up is 400w led 34-36 inches away and 120w cfls about 6inches. They are finally 4 weeks old. And they are topped. As you can see below. now I've already topped the tops cuz the pics above are a week old. Still are 4 weeks old. And another thing they are in ffof. But last night I noticed this on my leaf. And seems to be getting worse. I researched the best I could and came up with cal or mag def. So I decided to flush. Run off came out to be around 5.0 5.5. Really bad stuff and after the flush got it to be around 6.0 to 6.2. Now I'm a bit lost on what to do. I have ffof trio and cal mag. I was going to wait till the soil dries up a bit to use these nutes. How should I go about this guys? Sorry for noob questions but hey we all started somewhere right lol.
