I have to agree ... growing auto's is a whole new ball game. I've had people tell me it's the same as growing photo's accept for the light schedule & flower time. That is not true at all from what I'm learning so far. Soil is different as you want it to be a lighter / fluffier mix so the roots can grow faster. Water schedule is different too. I only watered once every 2-3 days with photo's & according to Autobeast I should be using less water & watering twice a day. I'm having a little trouble also but my trouble is just getting them to grow. I had one pop up about a week ago & it isn't doing anything. Still only 1" tall. Also had 1 die right after it popped.
Someone told me to mix my soil 50% Biobizz, 20% Coco, 20% Perlite & 10% Vermiculite for auto's. When I told AutoBeast about my mix he asked me why I mixed anything with the Biobizz & that I should have just used it alone. I'm going to leave the 1 plant I have in the mixed stuff & hope it takes off but I'm going to use Auto Beasts thread "How to grow a perfect Auto-Flower from start to finish" when I start my new plants. He seems to know quite a bit & comes highly recommended from other people. I can tweak things later after I get an auto grow under my belt. Seems to me autos require a lot more attention to detail than photo's.
Right now I'm just glad I have 2 photo's going into flower this week that are really big. The 2 plants completely cover my 4 x 4 tent so I should get a decent yield. I cloned them just in case I don't get this auto-flower thing down soon enough. Besides, I love the Fire OG. It tastes so sweet & has a killer high.
For shits & giggles I'm going to take this 5 gallon bag of mixed soil & mix it with a 5 gallon bag of Happy Frog / Ocean Forrest I have already mixed that I use on photo's & try 1 seed out in it to see what it does. Just going to start it out in a 16 oz. cup & if it does what it's suppose to I'll use the mix & up-pot it to a 5 gallon bag. If it don't ... it will be added to the tomatoe garden outside for my wife to use.
