DISCLAIMER: This post is not an original. I gained this knowledge from a very experienced Auto grower and felt the need to share with others to help clarify autos since they have come such a long way an are becoming real contenders.

The life cycle of auto flowering cannabis.

Another common question I see is when to switch autos from veg to bloom. Many people are under the impression that as soon as they see the first flowers it's time to switch. Perhaps a little explanation of the life cycle of autos will help to clarify this.

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.
 
I've seen this article before and it had this along with it not sure if anyone is using BioBizz products but I figured it could be a reference point for nutes on a auto. Will adjust with the development of the plants like always. Only I don't use molasses but i use topmax and alg-a-mic

Thanx to Atrain for this guide.:bravo:
I used this post as a guide during my 1st and current run with autos and I love the results.:circle-of-love:
Sticky worthy indeed. :thanks:

Thanks for the info Atrain. I have 2 free autos (HW Fast & Vast) coming shortly. Never bothered with them before, but since they're free.....


Hook a brother up on a link or info on making fem auto seeds with colloidal silver? Spray the same as any other plant, or is the timing different on an auto? I'm willing to forgo usable medicine on the first two in order to produce a few hundred (or more) seeds.

:thanks:

I've seen this article before and it had this along with it not sure if anyone is using BioBizz products but I figured it could be a reference point for nutes on a auto. Will adjust with the development of the plants like always. Only I don't use molasses but i use topmax and alg-a-mic

Nice one Spart. :thumb:
 
Thanks man but i take no credit for the schedule. I can honesly say I've never used it either maybe i'll try it on a few autos next run. I got another schedule the grow shop gave me as well they had planed out for biobizz looks basically the same but they added in the topmax and alg-a-mic.

It won't let me upload it I'll pm ya the link.

Im using Biobizz grow and bloom nutes + Overdrive this time round... Have a small sample 30ml of overdrive, unused really..Mainly mixed with aquarium water... A simple compost for soil...

I have used molasses in late flower before

Thankyou for you time, fellow grower

:Namaste:

Definitely not Nitrogen def..... looks like it could be mag def... the spots and it looks like your stems are purpling.. I would get a cal mag suppliments with 0-0-0 values and add to your regiment
 
Tips of leaves gone light green and claw down also since yesterday. Wondering if nute lock was told by friend who hydrp grows to make up feed to 1800ppm so I did but that was 24ml per 1.5ltr now pot has been wet for 24hours
 
Thread starter #20
No you friend may have hurt you... 1800 ppm is VERY high... the clawing is usually TOO MUCH nitrogen... or too hot in the environment.. it's also important not to let your pots stay wet. It can lead to root disease. I would give straight water with a cal mag additive next if possible
