hello gardengal; request more information...I am assuming you are a professional grower,therefore a pre- emptive IPM/Sanitation flowchart should be in place from the start...My initial inquiries are:do you implement Pest Strips for insect ID and what allocations of your budget are designated for professional publications....

Hi Gardengal,
Wanted to add something here in the remote chance that you don't have flowcharts in which to glean info from (Pickwick, you forgot SPC charts, you gotta have SPC charts!).
Keep in mind that I'm new at this and learned the following from the internet when some of my seemingly healthy seedlings keeled over. Could be overwatering or underwatering. I use a moisture meter I got for a few bucks at the hardware store. Could be they need more nutrients. I use 1/2 strength once a week. If it were damping off you would see the stem near the soil look kind of shriveled, but usually only happens to small seedlings and is encouraged from overwatering. Larvae of gnats will eat at the roots of seedlings either killing them or stressing them out, again overwatering atracts the gnats in the first place. I spray the soil around my seedlings with a fungicide/insecticide. Don't really know if it's working because I still see gnats. If none of this helps, go with Pickwick's suggestion, and don't forget the statistical charts.

I appreciate the assumption that I am a "professional grower". But I am not, just a gal who loves to garden. I took the plants out of their pots and the center around the roots was very wet. Even though the outer area was dry. I re-potted and added perlite to the soil. I'll see if this helps with the leaves wilting. I think from now on when I re-pot, I will continue to add perlite to the miracle grow potting mix.

hello;there is a gardengal70 KC....Anyway,keep us informed...I would consider using hydrogen peroxide at the recommended rates(3%stock)>(1H2O2:9H2O)to oxygenate the media at the next scheduled irrigation....I am unfamiliar with MG;if it is soil-based;scale back the frequency of fertilizers
Kris...yes there are many corellations with SPC..please keep in mind that chemical usage should only be considered as a last resort as the younger the seedlings, the more severe the injury with chemical intervention ..(also use extreme caution in the home). Therefore, sanitation should receive a high priority from the start.. There are some useful flowcharts/tables in vols 4 and 5(USDA Handbook674 (Dr. Thomas Landis)(particularly volume 5 (abiotic/biotic stresses)I think they are available for reading online (dismiss the chemicals,though)...too tired to link...sorry

hello Kris:good thinking on your part....SPC is used extensively in this field from graphically tracking leaf unfolding:(scheduling crops);total seeds sown vs. plantable germinants ( factoring in expenditures-time ,effort,money,crop selection);best management practices; and so forth... It is not one or the other ,but the integration of both...
