Kinda hard to tell without more info on the plant or a pic of the plant
I know. The plant has been in super soil for no more than 5 days. This is occurring on the bottom fan leaves of the plant and it's creeping up the plant. It's happening to all 9 plants. I looked at lots of charts and without knowing more info, I have narrowed it down to a few things. I didn't think anyone could tell me with such little info on the plant, but I had to ask. Trust me, this shit isn't happening at my home grow with the super soil I made. To be honest, I never have to deal with shit like this because I have a system that works and I follow it carefully, and have for 3 years now without fail. I'm great at controlling my grow, but when others work with me, I have no choice but to trust what they are doing. This is the doing of the boss man wanting to take short cuts and not following a recipe to the "T". I know the cliche, if you want something done right, you gotta do it yourself.
That's all fine and dandy, but I still need someone who knows disease really well and has seen this before and fixed it; to please help me out. Otherwise, I will have to re-pot 7 plants, tomorrow. They have 10gal root balls and they are in 20gal pots now. Not looking forward to that...
