Here are the answers Rusty, thanks for the inquiry.

It is the soil girls that are giving me trouble. The COCO have only been in flower nine days and look nice still. I am afraid they will take a turn for the worst like the rest of the ladies. Most of what i have is soil.

I wait until the top inch of soil is dry and then i water with about 20% runoff. Anyone have a good way of deciding how much runoff is a good time to stop? I usually wait till i see water come out the bottom and then count to twenty.

I have flushed the girls once in the last two weeks. About 10 days ago.
The mold issues i was having were on two WW from my last grow that i left in the room. I was spraying them heavily and often with Serenade to prevent any migration of mildew to the other girls. That is why i also sprayed the Baking Soda on the new ladies. I have not had mold issues since, but the girls were covered in white(baking soda) the day after, and lots of burn occured on new and old growth.

I have a few fans in the room moving the air around. Two on the floor mixing the cold air and one on the canopy blowing over the top of the plants.

The lights i have are air cooled with 8" inch duct and are kept about a foot above.

I amended the soil with 25% more perlite. I had overwatering issues on my first grow and thought this would help. It seems to have.

I forgot to mention i have been foliar feeding everything except the girls i burned with the Baking Soda. Those are on half the room and the other half have been receiving Liquid Lights with Penetrator every four days for the first two weeks. My hydro guy said that would solve the early yellowing of leaves. I also used Reverse on day 1 and 10 of flower for the whole room.

I will try to post some pictures tonight when the ladies rise up.

Thanks again
