Too many plants not enough light... for three plants you need atleast a 400 WATT HPS or a 600 wat hps if you want your plants to grow and faster... but keep in mind they make the room a little warmer. (this may be good if your plants are cold)
tell us about your setup so we know if something is wrong..
you need to check the water P.H level... if your using soil try to aim for a P.H between 6.5 - 6.8 if your using rockwool and hyrdo style its lower at 5.5 to 6.0
are you feeding enough nutrients or not enough?
what is the temperature in the room?..
how is the humidity?
is there a fan oscilating at medium speed?
if its hydro whats the E.C level of your nutrients?
how big is your room? how many pots and how big are the pots?... are you still veg or in flower? because at flower they focus more on making bud than growing.. etc.
how far are the lights from the plants? how long are the lights on for?... vegging.. 18 hours on 6 hours off... flower is 12 hours on 12 hours off. (undisturbed)
how long ago did you top them? sometimes certain strains stay in 'shock' for longer then recover.. sometimes a week to start growing again depending on conditions..
you need to explain yourself a little better if you want better answers... sounds like your plant is in a little stress if you topped and started LSD.. its not used to as its best to do that from seed to mature bloom before the stems and branches get thick!
