Thanks Colombo. That is a very informative article.... The single and triple bottom leaves went first, and then the new growth got in on the act. Maybe a total micro-nute lockout?.... I am going to flush my plants with about a 1/4 strength mix of GH Florogro, and PH the run-off. Just got it in today and am waiting for my tub of water to warm to room temp. .So in the morning.........

Thanks Mohsen. I hope that is the problem. I also was using incorrect nutes...... I have grown rather attached to 'Crash', 'Sister' and 'Jack'.
