Well, I've been concerned about over watering, but I live in the driest place on earth practically, and when I water, I rarely get anything out of the container anymore, so I've bumped up the amount but not the frequency, which in my case is every 48-60 hrs.

I fed the plants. I followed the directions on the fox farms website and gave each 3 gal container 32 oz of food/water mix. That was at 11 am, and now at 10pm the top growth areas of the plants are going nuts and some of the side shoots have poked through the canopy. One plants top was kinda limp and it has strengthened and straightened.

I guess they were hungry. Good thing the FedEx guy came on Wednesday.

I don't hold out much hope for the previously affected leaves but they are all low on the affected plants.

Here is a macro pic of some of the new growth on one of the plants.

Thanks for the advice. Time will tell...
