Can you give me some guidance on topping?

A customer has a question or concerns and I hope we can get some opinions on it, thanks

"Can you give me some guidance on topping my plants? I’ve never done it before and want them to yield as much as possible…when do I do it? Can it be done with auto plants? They are outside and will be in the greenhouse in a raised bed planter once our temps here break the 90s this next week…(still a little too warm in there). I’m wanting to top them but have never done it before and need some guidance. My plants have been outside for approx 10 days… about 8 inches tall… I tried to topped them 4 days ago and now they look like they are going into flower… I see small white hairs on the tops… is this normal with the auto flower strains? Please help! Attached below are 2 photos. They look like they are flowering… it’s way way to early… it started once I topped them about a week or so ago, and they are only about 8 inches tall so far.

  • Strain (type, bag seed): amnesia auto flower
  • Soil in pots, hydroponic, or coco?: m3 mix
  • PH of runoff or solution in reservoir?: unknown
  • What is strength of nutrient mix? EC, or TDS: none water only formula
  • Indoor or outdoor: outdoor
  • Light system, size?: na
  • Temps day, night: 85 to 90 day…60s night
  • Humidity day, night. 13% or lower (in az usa)
  • Ventilation system (yes/no, size): na
  • AC, humidifier, de-humidifier?: na
  • Co2 (yes/no): no

More info…dates: these sprouted starting 25 to 30 Sept and stayed in cups til 15 Oct. I transplanted them and went outside where they are now. Temps have been about 90 here in Arizona. Very low humidity… beautiful weather… I topped them on 22 Oct and now they look like they are flowering at the new stems. I don’t get it. They are only about 8 inches tall. They stretched a little but not bad at all. Once I topped them they seems to sprout at each leaf location and are taking off very nice, just these white hairs are confusing me. I need advice on what is happening. This is my first time doing auto flower seeds. Is this normal for this to happen? They were listed at 9 to 12 weeks to flower. This isn’t even half way to that point.

That’s a pre-flower and your gals are now in flowering stage. Any further topping is not a good idea. Autos are strange little plants. I have a Fruit Punch Auto that was about the same size as yours when she flowered and took off growing. During flower she added over a foot in height. I’m learning that autos do what they want, when they want.


I must say I am not very impressed with this grow…only about 8 inches tall.STILL and in full on flower…they are outside here in az USA…at this rate I will be lucky to break 28 GRAMS in 10 plants…what the heck went wrong???..ive never done autos before is this normal???..

So, they aren’t growing taller? That does seem a bit strange as my autos have all made it to about 2 ft. About all you can do with a healthy auto is watch and see. You won’t get huge yields,you won’t get huge buds. But, they are small so they can grow in limited space. And, the buds they do grow can be just as tasty and potent as the full sized.

I got this strain because of the description and semi HIGH yield…said 20 ozs per 3 cu ft area…no way in the world is this accurate at all…also said they would be approx 24 inches tall…again not accurate…i have 10 plants that will not yield much at all…i am only allowed to grow a total of 12 by law and this was just nothing but a waste of money…time…and effort not to mention NOW I WILL HAVE NOTHING TO SMOKE…!!!..the genetics seem to be flawed…I thought these people knew what they were doing breading seeds…guess i learned a serious lesson…they sure messed me up badly…i send in questions and get the same reply that is generic…im so pissed off right now i cant stand it…worthless amd will NEVER buy from them again…

Well sir everyone is entitled to their own opinion, and after the results of this grow I too would be fuming.
However there could be a 1000 reasons why the plants didn’t perform.
First off not knowing the ph of your medium or the water in which you feed will create nutrient uptake problems, plus it seems you kept them in a cup for 20 or so days . The auto genes grow faster and start flowering in about 4 weeks after sprout. Lastly you topped . Now with regular photo period you can top all you want,and with autos to some extent, but it is really stressful to autos and with the quick flowering genes it can stunt the overall growth

My mix PH is 6.5 to 7…same with my water…the main issue with this is they just dont grow…!!!..very VERY slow growing…takes forever to pop and then even longer to get any kind of size…they were kept in cups because of that…its crazy…but i also must say the seeds also were not of good quality…green and VERY tiny…out of a total of 15 seeds only 4 looked “decent”…i dont know what anyone could have done ro get any decent size out of these…im very disappointed with this in a huge way…guess its a lesson learned…a very expensive one…!!!..#buylocalUSAstock
