Autoflower growth weeks 4 onwards?

Hello everyone,
I'm new here and was just curious about a few things to do with my plants. I currently have 2 Bloody Skunk autos on the go, they are both 4 weeks old atm and only a few minutes ago did I go and check on them (I am currently LSTing them) and noticed that the smaller of the two plants is displaying a few pistols.

The first week of the grow I had no lights on them due to lack of money, but in the second week I got a hold of 2 5500k cfl 45w. I am aware that this is not the ideal amount of light needed for growing autos, especially if you are looking for more than a few grams of bud at the minimum, but I planted these just as a "hobby" or experiment if you please
Because of these factors my plants are only maybe 3-4' in height at the most (however they are currently bent over because of the LST so it's hard to determine their actual size).

My question is simply whether or not I should expect them to grow much more, especially now that they have started to flower. I read that you can expect a good amount of vertical growth in the weeks that my plants are in, but tbh I don't expect to see much more out of them, and regardless of the amount of journals I read from other people's grows it's hard to translate that information over to my grow.

I am aware that some of you might be thinking that unless you're growing them properly, under a 400w HPS or at least 5 CFL bulbs it's a "waste of time", but please I'm not looking for this, simply an answer as to what I can expect to see happen to them over the next few weeks would be nice.

Thank you all!

Re: Autoflower growth weeks 4 onwards...?

The life cycle of auto flowering cannabis.

Weeks 1 - 3. Once you've started your seeds and they break the surface of the soil, they are in their seedling stage. The first set of leaves to appear will usually single fingered, followed by a second set that may still be single fingered or perhaps 3 fingered. Once that second set appears growth will start to accelerate as the new leaves provide more photosynthesis. This process will continue, more new leaves, faster growth. Depending on the type of soil in use, mild vegetative nutes can be introduced at week 2. By week 3 most plants will start to show their sex. Males will start to produce pollen sacks and females will display pistols.

Weeks 4 - 6. The plants are now entering a pre flowering stage. During this time the plants should exhibit explosive growth, often as much as a new set of nodes and 1" vertical growth a day. This is the time when they will gain most of their vertical height. Many people make the mistake of switching from vegetative to flowering nutrients at this point, assuming that since they see flowers it must be the proper time. This is incorrect. If the switch to flowering nutes is made at this time the vertical growth will stop and the plant will put it's energy into producing buds. If you need to keep your plants small, or want them to finish earlier, they by all means switch nutes at this point. But if you want to get the most out of your plants continue feeding vegetative nutes until you see the vertical growth slow and stop. Depending on the strain that will usually be sometime during week 5 or 6.

Weeks 7 - 9. By now vertical growth has stopped and the switch to flowering nutrients has been made. The buds will start to fill out and put on weight, becoming hard and tight. Pistols will start to change from white to brown, orange, red, etc. By now the plants will also have developed a strong smell. Toward the end of this phase the large primary and smaller secondary fan leaves will begin to turn yellow. This is an indication that the plant is moving toward the end of it's life.

Weeks 10 - 11. At this time flowering nutes should be discontinued and only plain pHed water fed to flush the remaining nutrients from the soil and improve the taste. Yellowing of the fan leaves will continue as the plant draws the stored energy from them. Eventually they will die and fall off. By the time that the smaller leaves that come from out of the buds will also start to turn yellow. Then it's time to harvest.

I know that many of you are thinking that the seed bank said the plants will finish in 8-9 weeks, so why are you saying they take 10-11? The claims made by the seed banks are somewhat deceptive. If you switch to flowering nutes at week 3 or 4 the plants can finish in the times the seed banks say but they will remain small and not reach their full potential yield. Years of growing by myself and others has shown that autos do best if you follow this time line.

Of course, there will always be variations depending on the strain, the environment, nutrients, etc. This information is meant to only serve as a general guideline.
