when to bud? (pics)

i was wondering when to bud i have quite a lot of room but do not know how much bigger my plants will bud i have 3-5ft height (slanted roof) my plants are around a month old and i just wanted to know when to start budding and how big they will get any help is appreciated

with that space i would start now you have a few tops and it will grow in flowering alot so in that space i would do it now

I agree, even at that small of a plant, if u started budding now u still might find that u could be short on space.

i have 4 plants g13, bubblegum that is very bushy pic, blue cheese, super lemon haze will upload more pics when i find cable for phone. 2 of the main 4 are about 6/7 inches tall and the bubblegum is around 8/9 inches tall and very very bushyy and the g13 is 1ft maybe more just updatring cos pic old and not very cleaer, if i put into flowering nnow how tall will they be do you reckon

they grow at least 25% to 50% in flowering
