I'll back him with one exception. If you "KNOW" really know how to transplant they dont miss a beat. If your a noob let it be.
Soil is more important then lighting.
Auto's have funny tap roots and until you grow one you probably wont understand. They have a tap like normal but its short and stubby usually grows to a 45 at one side. When you hear people say that they veg until the tap hits .... Well this statement is partially right but for the actual tap root to hit. Then you would have to have a shallow pot like 5 inches. Ruderalis has adapted to harsh conditions like permafrost layers that are very thin so to survive it evolved to grow multiple large sideways roots.
(Notice the empty spot under the stalk I grabbed it by the stalk and shook it just to elaborate) Now the veg until they hit applies to these from my experience. I have pots that hold the same volume but some are tall and thin. But for some reason the square wide shallow ones always veg longer. This is why they have more reach.
Auto's growth will stop if over watered the easiest indoor mix i have found is a good organic indoor potting mix in ratio of 50/50 mixed with perlite. This promotes really good drainage which auto's love. try and steer clear of time released ferts to easy to burn your plants when using nutes.
For the feed/nutes even with 50% perlite a good soil will more then support a auto for 3-4 weeks. I have finished many nice plants with this mix only using water
best results were from using nutes 1/4 str at first then build up slowly.
I introduce veg nutes at show of preflower roughly 3-4 weeks. If your going to feed every watering then leave nutes at 1/4 str there is not much veg after this 2-3 weeks so these feeds need to be under max dose other wise a burn will greatly reduce yields at this point.
Preflower is not the sign to switch to bloom nutes unless you want a fast low yielding auto. If this is so then there is no need for veg nutes you want the N to diminish.
When the tell tale popcorns of hairs start to pop up over night. I use just water for 1-2 weeks depends on str of nutes i used in veg this just helps with nute build up and helps deter problems later on. Bloom nutes 1/4 str and build up
few auto's actually run for 8 weeks. i assume when i am growing a new strain 10 weeks have had them take aslong as 14.
I have topped and if its within the first couple sets of nodes then it actually helps i pull a 1/4 ounce more from my 1 oz strains
really it just relocates bud sites honestly extra weight is probably just stem weight but the scales dont lie.
Lst they love it absolutely love it SCROG remember this word if your on your first auto grow or a grow using led or cfl its a god send. For hid's this is the money maker in the right setup easily two to three times yield.
Auto's need no schedule when it comes to lighting common misconception is that a auto needs a dark period a true auto needs no such thing.They will run pedal to the metal start to finish under the right conditions. You may need a dark period for temps or your pocket book , If the breeder calls for a dark period its for the desired bud structure but commonly its the fact that they know that if you run 24/7 that the plant is no where near small or stealthy Dinafem white widow auto for example up until a year or so ago growers were advised to put it on 12/12 to bring out the best of this strain that was the claim anyway . But put them on 24 hrs and there 3' tall with a few weeks of veg left.
"cut cure smoke" <~~~~~ this is the autoflower section not gonna explain that one
