The chart calls out for 1120-1260. How in the heck would you get that high with this kind of dosage? -The recommended doses on the bottles are just guides to give you an idea of how much is enough. But if you are at 400ppms and want to be at 1200, simply triple the amount nutes in the water....


I read a lot of threads and it seems like people increase their nute strength almost weekly? Well if your plants are drinking the water and everything is going good, they should be drinking water/nutes at same proportions.. I know this wouldn't happen unless you had exact pH for your strain but still. Im confused on how you would achieve this. -After a couple of grows, you will notice that plants will drink more water than nutes when temps are too warm.... And will eat up nutes like candy when temp is correct.... pH is not the only factor that determines nutrient uptake.... Ideally, you want them to take in more nutes than water, proportionately....


Also, I read that 400 is ok for some strains to begin with.. but I think you still end up increasing ppms.. Im running two strains in my grow this time. White Skunk indica and blackberry sativa. How do you know what ppms are good for what strains? Below I explain how I understand your pH altering and finding the best pH possible, but how do you do this with ppms? What am I missing.. -You aren't missing anything other than te experience.... Right now you are over-thinking the situation.... 400ppms is a good place to start, work your way up from their until you notice a negative effect....which can be easily fixed if caught before it becomes a prob.... But as long as you build nuts tolerance correctly, you shouldn't have a prob with over ferting....


I found it very interesting on how you talked about dialing in on true pH for the strain your growing. As I understand it, you check ppms daily and keep a log. All you do is adjust pH up or down, and keep a chart of ppms. When ppms increase and continue to increase, you are going in the wrong direction because the plant is stealing the h20 out of the res, correct? -If I'm reading this part correctly, you water level drops and your ppms rise correct??? Is that before or after you top off your res??? Because if you didn't top off the res with fresh water, then you are taking an incorrect reading.... Your ppms should never be higher than when you initially placed fresh nutes into the res for that week....

Then if ppms are dropping on a day to day basis due to your pH changes, you chart the most significant change in pH which will be the best pH to run your plants for optimum nute intake? -pH fluctuates, plain and simple.... It fluctuates even more when you have small amounts of water.... What you want is to get the pH to fluctuate in the area that is best for nutrient uptake.... For example, if you notice that your pH is fluctuating up, you want to counter it and drop it so it will fluctuate from low to high.... So if when you topoff a fresh res and you leave your pH and 5.6 and 12hrs later it's at 6.1.... You drop it down to 5.2 so as to find out if 12 hrs later it will be at 5.7.... Know what I mean....find the balance...

Also, you can dose the shit out of your plants when you have the correct pH? -No, you will kill them.... In this case less IS more....not really but you never want to dose the shit out of them....until you know what you are doing....

When your plants burn its directly related to pH levels, salt levels.. ?-In some cases yes but not always.... It's very easy to over fert in hydro.... Learn to build nute tolerance....

Im a newbie so I wouldnt even try this until I complete my first dro grow. Thanks for reading.
