yeah it's connected to the blower

how many watts is the bulb and how aften are you watering. also whats the heat

agrosun gold 400w,watering 2 times a day for 30 min each and temp is 86.9f humid 44% 18 hours of light and 6 hours of darkness

im not hydro but i know my plants get like that if theyre not getting quite enough water. nuts dont seem to look like theyre a prob. plants look nice and green, think i saw a slight shade of yellow one pic which would be maybe a slight bump up with some nitrogen, but it coulda just been from the camera. id check with someone here who knows a little more about the type of hydro system youre working with.

also might want to see if you can possibly move the light a little closer, espicially if its a MH(cant really see how close it is in the pic) and maybe try to get it down a few degrees.

Concur, up your nutes man. Mine did the same thing, they would spurt, hold for a while, get unhappy, I would add nutes, another spurt.

i wouldn't be so hasty to add more nutes. whatever you're doing is working so until there's a clear problem developing don't try to fix things that aren't broken.

I agree with Kant and weediscool - i wouldn't add more nutes just yet. I'm not sure what the directions are for your watering system but it looks like drip. I use aero and the directions say to keep watering continuously while the lights are on (and for an hour during the middle of dark periods) - underwatering maybe? too hot?

these are the nutes im using might be abit weak.
summer ms 1.1-1.0-1.9 it says 40 teaspoons per 10 gallons i put 20 gallons of water in the res so that 80 teaspoons and fulcrum ms 5.1-0.0-0.9it says 10 teaspoons for every 10 gallons so thats 20 teaspoons i do this every two weeks
