This is bullshit. They will not "continue" to burn at 900ppm as they never started to burn in the first place.
You should not be giving people any advice on this plant problem section. I read through your posts and you have no idea. Sorry if you don't like or are too immature to realize it but trust me guy you are so off it's scary. These plants are some peoples medicine. For you to make stupid sarcastic un helpful comments on their threads is just wasteful and it doesn't take long for people to see through your BS. For other users if you would like to check people out how they post to threads in past and currently go into their user name and check out their posts.
You even give advice to growers on threads that haven't even given any background information on what nutes they're using, in what ratios, what strengths, what their grow environments are etc..Which is just completely wrong and impossible to properly diagnose. Not only that it's mis-leading and can cause a patient to completely lose their supply of medicine.
I am a professional grower. I have been a commercial med grower for 5 years, worked in large commercial grows before that for 5 years before that, and before that I grew for my own and family supply for 10 years before that. I have 20 years of growing experience. I have seen it all when it comes to mj. And I have seen guys like you try to be internet warriors trying to help growers in the complete wrong way.
Read over this guys posts and see how rude, sarcastic, and un-knowledable he is. And If true medicinal growers ever need my help feel free to pm me. I will show you proof of my work and offer help to anyone that needs it.
