ive been veggin 5 white widows from seed in a dwc setup. for light im using a 250w mh. im using dyna grow nutes. well every thing was going great the plants looked great at about 6 inches tall. last nite i changed the water, lowering it to an inch below the netpots and upped the nutes alittle bit. i started at 1 tsp of nutes to a gallon and went up to 1.5 per gal last nite.(2-3tsp is full strength) this morning 3 of the plants were very dead. totally wilted dead leaves. 1 seems to be fine and one more looks pretty bad but is still alive. i cant seem to figure out y they all died. i dont see any signs of nute burn. i used water from the hose but thats what ive been using the whole time. all i can think of is that maybe the water was too cold as its pretty cold around her in new england. any ideas?????? also is it possible to transplant from soil to my dwc as i have 4 more healthy ladies in soil. thanks in advance!
