Brown Spots
[quote=macnasty]hey rusty...
1) the fan is not hooked up to a hood. i'm using a reflector.
If using a 1000w light, isn't it a bit close, or are you using a dedicated fan to disburse the heat?
2) i rarely spray anything on them, but occasionally (less than once a week) i spray a weak solution of AN Jumpstart (seaweed extract) while the lights are on. I wouldn't spray anything on them until just before lights-out, or raise the hood. If forced to spray with lights on, make sure spray is a fine mist, not droplets, and raisde the lights if possible. Each drop of water is like a mini-magnifying glass on the leaves, which can burn them.
3) I'm not using any calmag, or any calcium or magnesium supplement. i thought my tap water would be sufficient. Could be...was just a thought.
4) my watering schedule has been consistent since they were young. they are exposed to a continuous spray from the aerospring, 24 hrs a day. Not being a hydro guy, I'll leave that one for the pro's, but, 24 hrs a day...isn't that a bit much? I grow in soil, and when my leaves are turning yellow, and greyish-brown blotches appear, it's usually from overwatering too soon after a flush. (beginning of root rot)
5) the roots are offwhite/cream/yellowish. they look extremely healthy, but i wouldn't know for sure since this is my first grow. some of the roots are almost 1/2 inch thick. the 2 plants share a reservoir which is about 12 inches deep, and the reservoir with the nutes is in an adjacent tub underneath, so that the roots are sitting in a very shallow pool of nutes (1/4 inch) at all times. Healthy white growing tips, and no slime. Sounds good to me, but mine are always in soil, lol.
p.s. i was thinking about using molasses and/or epson salts.
If unfamiliar with molasses and the use of epsom salts, would wait. Can do more damage than good, especially if plants are already stressed. A picture would sure help.
