your plants can handle those nutes dont worry, i start my plants off with a 500-600ppm after a week of water, however your ph is way to high, bring it down to 5.8, and your resivior shouldnt be warm it should be cool, get a monitor for your res temps they should be 72F, also your room temps should be about 5-8 degrees cooler, good luck


also my question for highseekerz: being that this is a hydroponic grow under HID lamps, and in this particular grow most would veg 4-6 weeks max, why would you advise someone that the sun leaves hold enough nutes for one month? yes its true they hold enough nutes to get the sprout started but being that this is a newb that information could be misinterpreted, im not picking at you by any means i just dont wanna see someone go down the wrong path when they could have gotten maximum results with proper nutrition, being that those plants are on there second set of leaves i would recommend raising nutes, i think its the temps and ph holding this grower back
