Should I start adding flowering nutes or keep veg mutes going

[Leo_dean]

Hi,
So recently my autoflowers got their pre-flowers, the plants arnt as tall as I would like them so would it be best to keep adding vegging nutes or to go on to flowering nutes now ? I have AG grow and AG bloom , I also have pk 13/14 , This is my first grow so any advice would be appreciated ,
Also are they too small for their age or am I being paranoid haha

The reason why they are so small is that you have them in pots with huge volume. Auto flowers are designed to flower no matter what after about 30-40 days. Up until then you are racing a clock to get them as big as possible, as fast as possible. With a small volume pot, roots get more airflow, and more O2. Plants grow faster in smaller containers, I would shoot for a 2 or three gallon container for the forever home of auto flowers. In fact when I grew auto’s, I started in a 2 gallon pot and finished in that pot, I wish I had gone smaller sometimes and started them in .3 gallon maybe, and then transplanted.
However, it is also worthy to note that with any stress added, this could slow down the plant growth, working against you in the race to the flower stage. This is why a lot of people don’t transplant autoflowers, because this process can stress and slow growth for a short valuable period that could’ve been spent growing. Topping and fimming autoflowers is also not recommended unless done super early, like 2 weeks in with a vigorous growing plant that can take the stress.

To answer your original question, I would start transitioning your feed. Start diluting your grow feed with the bloom feed, at about a 3:1 ratio. Then 1:1, then 0:1, giving 100% flower nutrients. I wouldn’t change it abruptly just yet.

Hi thanks for the reply, they are actually in less than 3 gallon pots, 2.6 and 2.4 or something I believe, I wanted to grow In a 3 gallon but had these laying around , as for transplanting and topping I chose to not do either because of the chance it would stunt the growth but I think I've done that anyway because they are So small , thanks for the Info much appreciated

Whoops sorry, autos don’t need a ton of nutrients but try switching slowly to bloom boosters

Whats your opinion on the size? Will I still get a somewhat decent yield?
