If you want an oz a week youl need 4 plants in flower all at different equally spaced stages that's not including drying time of 1 week and you would need plants capable of producing 2oz so baring in mind your using regular soil and basic feed let's say 4weeks vedge? So 4 plants in vedge also, then as 2 plants are harvested 2 are taken from the vedge room to the flower room and 2 mores clones are added to the vedge room. Youl need to upgrade your equipment to a standard enabling you to produce this yeild which means youl need to pay good money "FFS" it's hard I know but it's a must, I would recommend a 600w high intensity discharge light (HID) there's 2 types, I would recommend both, metal halide (MH) for vedge they love it and high pressure sodium for flower (HPS) you'd also do great with HPS for vedge and flower.
But with these lights comes a problem, a temperature problem, so you need to increase ventilation this fan would do the job for 1 600w light but it loud and need replacing after 12 months of use they seem to lose power and get louder

Sorry for waffling I'm just realising im only at the beginning of wot I need to explain and it's taken a lot maybe you kno a lot of wot Iv just sed already and u asked for a straight answer but the best advice i could giv in this situation is do not bother with them lights u have for anything other than seedling/clones, don't try to harvest 2 plants every fortnight it's alotof head ache plants need different amounts of plant food in varying strengths and varying denominations of NPK depending on there stage of flowering, which means making 6 different reservoirs of fertilisers at different strengths and ratios, it means makin sure you've always got clones in your propergator, it mean an uneven canopy height in ur flowering room, it's do-able but much easier to have 1 area for your mum and clones and 1 or 2 flowering rooms split 4 weeks apart but you'd be best to get propper fertilisers and better soil and bigger lights, Iv only touched on few things you need to research if you want to get good bud as frequently as you do, seems you got a lot of reading to do bro
this is the biggest one the other 2 I just transplanted into better pots so they are droopy my main concern is the redness
the first two are Afghanis the last one is a white widow fem and the last photo are my seedlings that I just sprouted
