No worries about me sticking around.
The 6-3-8 was CANNA AQUA VEGA.
I run 400w too.
Yeah plant looks a little unhappy.
Have you got plenty of air bubbling in your res?
30ppm drop in 24 hours is acceptable.
If it drops to 100ppm lower or more then add some more nutes.
What veg NPK nutes have you got?
DYNA?
If so just use your veg nutes.
A lot of folks cut back N too soon in flowering and it can cause airy buds IME.
My goal is to find a way to make y buds more dense, usually i have nice yeilds but the buds are always airy..not sure if its a nute issue or a light issue but i am running a 400w HPS over a small setup so i would imagine thats planty of light. im trying to refrain from bumping the light up to 600w as im in this to save money not waste it on in neccessary watt usage on lights.
the hydro unit has the biggest plant. there are 3 small seedlings that are going to stay small and shouldnt get in the way, obviously if they get much bigger i will have to raise the light and up the wattage which i dont mind doing if necessary.

I used to run a 600w in my area before I got busted.
Dropped my light down to 400w and my yields have increased lol.
But so to has my skills.
