Nothing. I don't get what you mean?? What's the purpose of it? Sry I don't get u. Have a look through my diaries. I went mad with defol at the start. With autos less is more. There window is so short unless it's for a reason very little is needed. But in saying that I had 5 autos in a 70x70 so I had to defol and even then RH was still in the 70s in mid flower. Way too high. But after getting it under control I left my TDA to be herself and she was nearly kilt off and I saved her with defol in veg and then left her 5 nodes, not sets 2.5 nodes and I got 300g wet off her and 57g dry - stems.
