I have noticed that equal portions of N to P an K can help with the female ratios but the higher N is certainly more helpful. So around the 3rd of 4th week of growth make sure that the ratios are good and that P or K has not gone above the N and P or else more males will occur. Obviously this means to avoid overfeeding your cannabis plants around this time too.
Feminized cannabis seeds work on the bases that there is a genetic predisposition for the plant to produce females because of special treatment that it gets in the selfing stages of a unique XX female. I won’t go into this in detail here because there is enough information on the process across the entire internet. Anyhow, in an optimal growing environment it is very easy to produce ALL females from these treated female marijuana plants. OPTIMAL is the key word here because in less than optimal marijuana growing conditions strange things start to happen to these feminized weed seeds.

Now I believe that the genders are set in the weed seed however the environment has a massive impact on how this is expressed in the final phenotypic expression of the cannabis plants gender. There are probably many genes that govern this, however lets get into how to up these female ratios.
Anyhow for starters we better reproduce what Dutch Passion have to say about their feminized weed seeds first.
No stress during the 3rd to 4th week of vegetative growth. That is all there is to it. If you got your garden growing in optimal conditions without marijuana plant stress then the impressive 90% to 95% females start to emerge from standard cannabis seed packs. I find that topping is best done at the second to third week of vegetative growth but that this is a little stressful and can lead to those female ratios dropping again. Avoid topping or pruning if you are looking to up the female count.
Apparently environmental influences affect the sex of the female cannabis seeds as well. Because of the fact that Female marijuana seeds do not grow into female marijuana plants under all circumstances. Thus we changed the name from “Female Cannabis Seeds” into “Feminised Cannabis Seeds”.
But of course, not all strains act the same in our body, you will know that there are some that contain a ratio between THC and CBD diverse, which can go from 1:1 to 1:30, as can be the other way around, from 1:1 to 30:1, and between them any combination. In addition, during the last years they have appeared varieties rich in THCV or CBG, and even some that contain so much CBD as CBG but hardly generates THC.

This balance between THC and CBD is special, as it is doubly effective, and the patients can take advantage of the benefits of both cannabinoids separately, and of the synergy that produce when they act jointly. In this case the cannabidiol cancels a great part of the psychoactive effects of the THC, the reason why we will feel less high. But that does not mean that the properties of tetrahydrocannabinol are inhibited, it is not like that, it will continue acting in a therapeutic way, but without getting us crazy, and avoiding feeling ” hangover ” after the use.
Users of therapeutic marijuana of nowadays have more medicinal varieties to choose from than ever before. If you take a look at the catalogs of the seed banks, you will notice that there are many genetics oriented to the medical or pharmaceutical market.
They were the first varieties of cannabis rich in cannabidiol that appeared on the market, back in 2011, and there were even some that already enjoyed that strange chemotype before but we did not know it. In this list you can find what we consider to be the best strains with THC:CBD 1:1 chemotype, as they also have a very suitable terpene profile in this regard:
