I personally have never ran 15 gallon
smart pots, but that seems good. U getting good runoff from ur plants when u do water right?
Like u put in 500PPms of solution at 6.0PH ur run off should be the sameish.
I too judge when they are ready by how heavy they are, but when working with that large a container i doubt that is an accurate way to measure. So ur going to have a conundrum there brother.
As far as bacteria stuff and boosters for ur roots. I'd use
Great White,
Hygrozyme,
Superthrive, and if u wanna get fancy replace ur GW with Primordial Solutions
Sea Green.
I saw that u were also having issues with bugs. Happens in damp basements unfortunatley. U may want to pick up some Hot Shot Pest Strips to hang around the room just as precautionary steps. But also u got some neam oil too ritght, u using that too? Probably the reason ur plants are looking shrivald some. U want to use that stuff right when ur lights turn off, and mix it light. Spray them good and let them dry for atleast 6 Hrs before turning ur lights on, and wehn u do turn them on make sure they are set high above the plants some.
Why u getting Maylar? That stuff sucks to work with. The stuff u already put up has a cousin that is white she would do the trick for u, and she is cheaper. lol.
U will be fine with ur ladies and ur root issues as long as u continue to make sure they are getting good root health. Whats got some junk in the trunk normally caries some junk uptop too. lol.
And for future referances ull get allot better attention if u ask politely instead of making a fool of urself to get the help u have been trying to get. I seen ur other posts, and im sorry no one jumped to help u, but u gotta understand brother nothing is given with out first being earned. U understand?
I will try to help u the best i can, but just keep the fag name calling to a minimum please. remember brother respect k.
Peace and happy growing,
