You're looking at 7g dry from a 35g wet weight.

It seems that you suffered a lot with bad ph... and the plant struggling to uptake nutes.

I believe you locked out nutrients, and stunted the plants ability to grow properly... good thing though, at least your honest... we get guys on here that claim 4oz a plant when using fluoro's.

So, it feels good to talk to a truth teller... next time you're going to need a way of measuring ph, and ec... oh, and a HID lamp. Also a strong fan, and a way of ventilating heat. This could be something as simple as leaving the grow area door open.
