why are my leaves curling?

Hey guys i think i got a problem, my leaves are curling i'm posting some pics can you please help?

• set up drip/drain
• driping water for seven min three times a day
• rockwool/hydroton medium
• growing pacific shark

o and my seedlings are about a month old my nutes are 350ppm

wats ur PH @?

also u may want to change ur drip 2 a 24/7, but may not b ness. when I grew in drip I driped24/7 w excellent results.
but Need to keep Ph in check or it will deff cause prob.

i adjust the ph everyday to 5.8 but i noticed it will go up everyday to about 6 before i adjust it down again. I read though this is actually a good thing and will prevent nute lockout allowing different nutrients to be absorbed at different ph levels.

if i drip water on them all day won't that be too much? i started off my seedling with 15 min three times a day but i found that to be too much. my plants are alot bigger now, so you think i should up the water?

perhaps ull find sum hlpfl info here .

not necessarily, It worked for me Back then but if u say its not wrkin for u now then its prob not a good idea, but ull b amazed @how much the can drink when they start a grwin.

here is a pic of the drip system I used, 400 watt MH

checked out that article, and i'm pretty sure my ph is on, never doing below 5.8 and never above 6.1. my nutes should also be good i'm using bonticare nutes liquid karma, pro grow at the full recommened for seedlings putting my ppm around 350. my guys did suffer slight nute burn about three weeks ago as i got a little eager, but seemed to recover very fast. But the article didn't say anything about curling of the leaves. I'm nervous about the watering because its the only part of my system i can't really monitor accurately. I mean i can change when my pump goes on and off and for how long, but i don't really know how many mL's each plant is getting. Do you think this is my problem?

this is the set up i have. four 24" agrosun full spectrum, four 26 watt cfls with reflectors.

So, hows it bn goin man , bn a few since Ive seen ya around, although Ive bn gone lol
En updates? U get it all under control?
