@Bplatinum9 I want to apologize if I came off as combative. I sincerely didn’t mean to. I don’t blame you at all for not recommending a technique you haven’t ever tried. I did not mean to contradict your thoughts or opinions and if I did, you have my apology.
@Angiebaby I have to say the yellowing is concerning, especially on the later growth. I see your water temps are ok at the moment. However, without knowing the pH level or TDS reading, it’s really going to be difficult to pinpoint what’s going on.
The TDS meter will tell you how many Parts Per Million of dissolved nutrients are available in the water (basically, the higher the PPM the higher the concentration of available nutrients). However, the nutrients can only be absorbed by the plant at certain pH levels. For instance, if you get much below pH of 5.9, you will lock out Calcium. This chart shows you what nutes are available at what pH levels.
The reason this is important is because some of what your plant is showing might be certain nutrient deficiencies, which could be caused by pH being out of whack, or there just aren’t enough nutrients in the solution…or the roots could be rotting. All of these things could cause what you are seeing.
Also, if you are still fighting the dampening off issue, the Xylem (carries water) and Phloem (carries protein and sugars) might not be transporting water and nutrients properly to the branches, causing the same type of issue.
all in all, cannabis is pretty hearty and not terribly fussy. I think that perception has been slightly skewed on here due to the amount of problems people are seeing, and lots of folks think this is a major challenge. It really shouldn’t be if you know what to monitor and take the time to gather the info. Other than that, it’s going to be a flip of the coin.
At this point, I think you are on a slow downward spiral and just wasting resources on something that can’t be saved in its current state.
