Week 3, 25-31 October 2023
15-31 October - She is making steady and even progress daily. At this young stage in the plants life, environmental stability is the key to success. For the DWC grower this success will be directly linked to the value of your potential hydrogen (PH) range adjusted between 5.5 and 6.5. This should be viewed on a more narrow scale of 5.8 and 6.2 considering the values required during uptake of some nutrients, which is more appropriate. I find the sweet spot on most of my grows to be 6.24.
Hydroponic plant roots sit directly in water 24 hours a days. Normally this is enough to kill something non aquatic. Add constant aeration and nutrients to that water along with the proper PH and the plant will thrive. Of course there is a bit more detail to it than that, but that is the basics. PH has the power to lockup nutrients on the extreme low and high end of the scale. This means your plant cannot take up or absorb some or any nourishment to grow in a healthy manner. It will reflect it through deficiencies of all sorts leaving you to figure out what is wrong. Daily checking and correcting PH is critical, if not it could lead to the demise of the plant.
Grow Diaries just released an article 29 Oct 2023 (an excellent and easy read) in their journal that discuss these deficiencies along with pictures and corrective measures here: https://growdiaries.com/journal/nutrient-deficiencies-in-cannabis-a-complete-guide
The DWC setup doesnβt have to be elaborate. Simply checking/correcting the PH once or twice a day (or more) is sufficient. What do we check it with, strips or a meter? Strips are not accurate enough. Without a well calibrated PH meter it is likely you will have frustrating problems, and the plant will have a difficult, unlikely journey to maturity. It is not recommended for the serious DWC cultivator to consider growing cannabis without the ability to read, correct, and control the PH levels. It is a recipe for failure. Once you determine the method to accurately read PH levels, now you will have to correct them. There are two buffer solution that will do this, PH up and PH down. These solutions are very acidic and using just .5 ml p/gallon at a time can change a PH value significantly by .5 or more. Be careful when adding buffer solutions for corrections and take a reading after every adjustment until you reach your mark. Once the desired level is achieved your set. Check and correct daily. This can be very effective for up to 24 hours or more especially if you have PH stabilizing nutrients that keep your solution close to the same reading. If you notice that your PH readings are taking a drastic drop or serious increase that require bold corrections daily, it could be a sign for the need of new nutrients, consider when was the most recent change. The more you become familiar with growing in DWC the easier it is to understand. The plant speaks to you through its leaves and its roots, you respond in return by providing a conducive growing environment. The goal must be the ability to interpret and understand what she is trying to say.
Self research is the best teacher in the world. Experience with this knowledge will give you the edge and necessary tools to build upon, and pass that working wisdom on to others.

That is it for this week. Thanks for the read and stopping by.
Thanks for stopping by @Hologram, from what Iβve seen, usually nothing Runtz about her, but we will see if I have the same type of grow. Quality over quantity in any case, with a smile watching her bloom! βοΈ
