Yes but not exactly pH values may change the PPM values but because pH is the amount of volatile Hydrogen ions your solution contains and it dictates the nutrients availability to the plant! so basically pH affects what your plant will absorb **but will not show on your meter. And actually the opposite happens quite often (salinity changes the pH levels) because some minerals like Calcium and Magnesium will increase the pH levels of the solution. Hope this helps! Good luck and happy growing :)

Well there we go! the simple issue you are dealing with is general overfeeding at this early growth stage of the plant. during this early stage the plant is more susceptible and more sensitive to overfeeding, that's why growers often dilute the recommended fertilizer dosage they use to about 1/5-1/4 in total (0.2ml/l instead of 1ml/l for example). Right now for you I'd say first reduce the amount of fertilizer used to about 0.4ml/l, and increase the amount of water you irrigate! watering with no runoff may cause salt buildup that will eventually cause toxicities. Make sure to irrigate until at least 20-30% of it comes out as runoff!! for a 10liter pot I'd go with at least 2 liters of water or until desired runoff amount achieved (ideally you want about 30-40% runoff). your plants barely suffered any damage so if you do this then your plants should come back to full health in no time!

Since the last post I have been rinsing with plain water I currently do not have a ppm meter So I have no way of knowing these values In terms of acidity level 6-6.5 before and after irrigation

Well it depends on the parameters you currently have! knowing just the PPM and pH values won't help you determine what the issue is because it does not tell you exactly how much of each nutrient there is just the general conductivity! Lets start with directing me and everyone else to the correct plant diary you're having issues with so there'll be more info about your setup. Once we know that check the tap water PPM/TDS (normally around 200-400) so we'll know the salinity of it (which will also indicate if that's the problem) and if it's useable as irrigation water. Then once we have all that info we can determine the issue and how to fix it! To address your fertility regulation question, yes!! with proper diet and irrigation you'll have complete control over your growing medium's fertility! First you'll need to fertilize consistently and according to the plant needs (I'll address that in a bit), balance the solution's pH to the desired 6.0-6.5 range (5.0-5.5 for hydroponics) and to irrigate with at least 20-30% of the irrigation amount as runoff. This will leach out accumulated salts from the growing medium and replace them with those you put in! Ideally you want the same parameters coming out as in. As for the proper diet for your plant there's no right answer because every plant is a little different! each strain and each plant of that strain (not a clone) will require different conditions and diets. To find the right one for your plant you would need to start with lower than recommended dosage of fertilizer (from the fertilizer label), usually about 20-70% weaker depending on the plant's maturity and growth (bigger plants require more fertilization), and slowly increasing it as the plant matures unless a toxicity/deficiency appears and then you adjust the diet according to that issue!.

Bluntzilla First of all thank you very much for your very detailed answers You definitely know what you're talking about My goal is to treat the problem of burnt edges in my plants Apparently the problem is in my control of the ppm values And I try to understand what the dynamics of the process will be That is, if my water has the right acidity and conductivity and I plan to add nutrients Will i be Can I successfully regulate these values Or will I go into an endless loop of adding nutrients, acidity regulators and distilled water?
