i have a 400 w light about 20 inches above a couple plants that are on their 4th nodes. my female is starting to brown from bottom up and the top nodes leaves are starting to get brown and twist. my ph is 5.9 in hydro dwc and i only have 2 ml of flora grow/micro/bloom in 10 gallons of water. i have a thermometer at the base of these plants and its showing around 75F. also i have a oscillating fan on them and no light is getting in the reservoir. the plants are about 3 1/2 to 4 inches tall (lowryder2) and its on the 5th week. am i not feeding enough? is the light too close? anyone got any ideas? one of my plants is looking really nice with no burns and hasnt showed preflowers yet but the female has started its pistils. im afraid ive over nuted them. but 2ml of each of those products in 10 gallons of water seems MILD ...really mild to me. like on life support almost. any help is appreciated
I can't provide much if any insight on hydroponic grows, but I found this thread to be helpful in diagnosing problems with my grow: http://forum.grasscity.com/sick-plants-problems/25983-nutrients-bugs-various-problems-guide.html
