What to expect?

Hello all, I am in desperate need of a community who is active and has knowledge they are willing to share. I am a medical patient in Canada and i am legally growing my own marijuana. I am growing 5 White Queen (strain indica) in a rainforest 66 (system hydroponic using FLORA SERIES NUTRIENTS), with a 1000 watt MH bulb on a 18/6 light schedule. Currently they have been vegging (growing) for approx 54 days, It cud be 48-58 i lost track of when i started them. I am wondering:

1) when do i start to harvest?
2) what should my expected yield be?
3) How long should i flower them before i harvest them

ps. my tallest one is now 2ft 2inches tall, lowest is 1ft 7 inches tall. i was told they could grow
an other foot or two while flowering is this correst?

I have attached some pics of my room, i will add more tomorrow when my light is back on.


ALSO can someone experienced help me understand nutrient ratios? i know i wanst using enough nutes at the beginning, and i think i am now but i am not sure.. i am using flora series nutes like i stated, right now i am using 8ML micro 8ML grow and 4ML bloom per 2.5gallons of water... anyone know more specific schedule i can follow? like...
week 1 : so and so ML
week 2: so and so ML
week 3: etc etc..

very nice and healthy.

they will stretch to about 2-3 times their current size once flowered.

not sure how long to flower that particular strain, but anywhere from 50-80 days is standard, although it could be more or less.

don't worry about what you'll yield. just keep them as happy as you can and let the results take care of themselves.

i personally would have put them into flower yesterday.

good luck!

thanks alot for the info. nice to hear they get approval from someone with the title marijuana EXPERT considering this is my first time ever growing any type of plant/weed. im going to take your advice, unfortunately today is a holiday and nothing is open where i live so i have to wait in order to buy my flowering bulb. ill prob end up putting them into flower cycle on wednesday.
