Plants require different proportions of nutrients during vegetation and flowering. Modern nutrient products are far more advanced than their earlier counterparts and now allow precise adjustments based on growth stage. Most hydroponic nutrient solutions are sold in a "growth" or "grow" formula for the vegetative growth phase and a "bloom" or "flower" formula for the flowering phase of the growth cycle. You should at least switch to the bloom formula because your yield will increase exponentially if you can max out your plant's capacity during the flowering stage.
A weak nutrient solution should be used for plants in poor growing conditions, such as low light, overheated gardens, and root-bound or crowded plants. It is also ideal for newly rooted cuttings and plants in the process of being transplanted or in transition between growing cycles.

Regular strength solution is fine for normal, healthy plants in ideal growing conditions. In rare conditions, you may be able to increase the fertilizer strength to capitalize on the efficiency of your garden. This only works if you have high quality lighting, ventiliation, and CO2 production that will allow your plants to grow fast enough to handle the extra feedings. Always make sure to increase the fertilizer strength gradually to avoid burning the plant.
In addition to the basic types of hydroponic nutrient solution, there are also various additives you can purchase to boost your plant's growth. Keep good records in your growlog of what additives are used, when they were applied, and the results (good or bad). This will give you a good reference guide on what worked and what didn't work for your future grows. Flush your hydroponic system immediately if you see any signs of an adverse reaction.
