I was just fucking around mate! You have the plants as your avatar... It was pretty obvious they were your plants.. just thought I'd joke a bit with you.
They look fine, just stretched. You shouldn't top them now.. they were always too far away from the light by the looks of them.
there's alot likely "not optimal" with your set up. By that I don't mean "wrong".. as you can see, they are alive right.. so you just have to dial in your set up. Why don't you go over you room set up and equipment list with us?
I'll go over mine and you can kinda copy me, but tell us your stuff and we can help from there..
I am growing cali Orange.
I am growing in a hydro/DWC set up
I currently am using 4' flourescent lights for clones and veg. I run 24/7 lights on for veg.
I veg for about a month or 12-18" and transfer to flower room.
I have my temp and humidity set at 80 degrees /40% (no humidifier)
I keep my lights about 3-4 inches away from the plants, but I will let them grow up to and touch the light without any problems so far in a year.
My flower room has a 1000Watt cool tubed HPS that I keep about 6 inches from the canopy.
temp and humidity is the same as the veg room.
I use GH 3 part nutes.
I flush for 10 days at the end of my grow using clearex.
Ph is only adjusted when I top up my res'es once a week. The PH stays between 5.6-and 6.0 without tinkering with it too much. That is the same for veg and flower res'es.
Now.. you have a good starting point on what I've been doing, and people can give advise on possibly things to look for to help out..
Like I know that my humidity is below optimum for my veg room. There's nothing I can do about it at the moment, but someone could point that out as something to work on. Know what I mean? You'll get more help, cause more people will be able to make suggestions based on the factors of your set up.
