If using Rockwool, how moist do you keep the medium? I have some sitting on an air stone with water BARELY touching the bottom of the cube. Then I have some that are just in a tray with a dome over them.
Look under the leaves where the spots are.. if you see little tiny white eggs and or little tiny black bugs you have mites. If not then I bet it's another issue.
Oh yea true.. I do that.. I thought he meant just doing straight 16/8 veg then going straight to 12/12... You at least want to start at 18/6 then work your way down a few days before changing to 12/12. Thanks for that heads up.
I've gotten rid of quite a few gnat larvae and aphids and other non-id bugs using potato chunks on top of the soil. Leave them for a couple days or so then throw them away. The bugs LOVE the taters and burrow holes in them.
I'm getting some lady bugs tomorrow.. do they help with gnats at all? Those gnats are bastards! I've done the potato trick.. and I've removed quite a few larvae but the gnats keep coming back. I have sticky traps everywhere and they have caught a ton of them.
:wink: I agree. MG fert aint' bad stuff, it's just how you use it that makes it bad. The soil is something else though.. wouldn't use the soil. I made the mistake of using a soil for roses and you really had to be careful when adding nutes.
Plant Success tablets are good for a nuteless...
Got my OMMP card and got my room almost finished. Just need to find Mylar. Enough room for 24 veging plants and about a dozen flowering plants. Running 4 6500K fluorescent and 2 5000K fluorescent bulbs for veg and a 1000w HPS Xtrasun bulb with Xtrasun hood. I just took these out of starter cups...
