First time indoors DIY box, cfl set up. Three weeks old. Could use advice

Im not a new grower. I have grown outdoors for years. What a switch coming indoors has been. These plants are my first plants indoors. They are three weeks old today. So far so good, but Id really appreciate further direction.

1. Should I transplant them into bigger pots? they are currently in 5x5's
2. Should I start feeding now? (recommendations on nutes greatly appreciated)
3. The box is 4' tall, with light about 3.5' to work with. At what height should I start flowering?

Thanks bruddas and sistas

slightly bigger pots, yes on the nutes start at 1/4 strength, veg nutes for like a week or 2 then flower nutes. and if you LST them you can get a lil more bang for you buck. Remember to switch lights from thos blue ones to red ones 2700k. Plants look nice and healthy!

I cant find a good guide on LST some links could really help me. Ive searched but its usually 16 yr olds on youtube growing out of plastic cups.

its really just pick a point on the plant where you wanna tie or pull it down from and loop you a string or something over it then tie it off on the side. but the thing is do it after you transfer to bigger pots if youre not then just tie it up on the side

do a rollitup search for LST guide and you should be good its easy trust me!

So these plants like my 18 others have now been aborted. My parents are fucking insane and looked through my bedroom window, saw light and threatened to call the police. Cant wait to not attend their funerals

Why can't you just wait till you leave their house before you start growing?

what contribution to the topic of this thread are you trying to make?

that stinkx man! I told my parents eventually. Told them it helps me save money and i throw in on the light bill. hope you can get another growing. 8/

cant wait to not attend their funerals.. lol
