whats up.... this is my first time growing hydro and i am having some problems, i have read up on it alot, and thought i was doing everything right, but obviously not i keep my nut. sol. between 5.5 and 6 grow room temp is about 87 degrees f i use hydroguard to keep the solution and roots nice and clean, i use excellofizz for co2 injection. and i have a carbon air filter that constantly sucks out air from grow chamber (except when using the co2) and an internal fan just for air movement to strengthen the plants up. and i actually have a cheap aeroponics setup. I leave the pump that sprays the roots on 24/7 (cuz the manufacturer of the kit said that will increase growth rate, and it saved me $80 on a cycle timer 1 min on/4 min off) i use liquid earth brand nutrients and supernova additive. i'm just about to hit 2 weeks since i started (from seed in rockwool) you can check out my pics, but they sort of suck, cuz the only digi cam i have is my cell phone, so i'm also going to explain whats wrong with my plants.. and if it matters, i have a blueberry breed as my plants. JUST the very tip of some of the leaves are wilting fairly bad (but not the whole thing) some tips are drying out, and getting yellow/brown/lighter shade of green spots on them. oh yeah i also forgot i am using a 125 w dual spectrum cfl light and its about 4 inches from tops of plants ( i am planning on putting it close once the plants get bigger, is that a good idea?) anyways, if anyone can tell me what i'm doing wrong i would really appreciate it, cuz i really wanna have a successful first grow, thanks.
are you using nutes yet? what strength? in the first two-three weeks using hydro tr to start out with 1/2 strength or even better 1/4 strength solution. hydro is a very volitile way of growing, and if you use too much ferts, you burn palnts and burn them quick, ive had times were in as litle as 4 hrs i get nute burn symptoms. good luck with your grow!
