dude im flowering my first grow now it will be the 7th day of 12on 12off and i think i had a salt build up problem from phosferous so i flushed the medium in the bath tub my plants are very big ive been told i waited too long too flower them they are like 3 feet tall already and the bottom growth has had trouble but the upper portions off the girls look good do you think they will still be alright i think your thread is the shit what advice can u give me thanx.
So at this point i am stressing the limits of penetration of my 1000 watt bulbs
i grow plants looking for 3-4 foot finishes you can see within the first 10 days they are really "leggy"
I veg 18/6 i really wont feed till the plants show they are starving, with good vigor i see this in 10 days.
once i know i need to flip the MH to hps will stimulate the plants to stretch way out. and the loss of light, 18 to 12 will also cause this.
i combat this 2 ways. mh in the first 10 days of 12/12 and stepping thehours down 18 then 2 days @ 16 then 2 @ 14
these just went veg to flower. This will make this batch very leggy. We really rushed this one out, next batch will have better cuttings and more veg time and intenisty.
the lock up you have... i avoid by waiting to feed starving plants, right before they flip i heavy feed, this causes a blue color to the leaves, this will load your plants with nitrogen. once you start feeding in flower the lack of nitro, and the hps will yellow and hinder your plant alot. keeping healthy soil and roots is not accomplished by one simple flush. once you lock up the plant its a fight from there. overwatering leads to problems. you need to say lean on food.
As for the height issue you need to know what you are flowering. most of mine if i start @ 3 foot would be 7 footers, and no light is that good besides the sun!
Bushmaster is a product you might try to stop growth, however @ day 7 most of your leggy time is over. If you top to late your retard will disapoint you also. kind of a no win.
For me, if i am @ day 7 and too tall
Stacker or purpleMAXX and or bushmaster those will halt that growth nearly instantly.
Use those AT half power TOPS!!!
