Am i doing this right? PPM

You can add what ever you want but when your done adding, add water to get your ppm down to 800 ish, then your at good safe limits for your girls. I already see your pistols going. You will have a reduced harvest if you don't adjust your levels soon. Some listen to me and are happy and thank me in the end, some don't, and I never here back from them.

Your wrong mate, trust me. I grew this way many many years. You will not get the max harvest, you will see your pistol turn brown/ red early into flower. If you have the greatest environment going indoors, then 1100 is possible, but that takes much money to create such an environment. I still grow hydroponics, but soulless. Have a look at my diaries. I am speaking on 46 yrs experience.

@NobodysBuds way over my head bro. Thank you, but I'm trying to understand ppm 1st. @gmslave, I'm faitly certain mate in hydroponics, when flowering, PPM csn be up to 1100. I'm just checking if I've worked out my PPM for my nute mix correctly. Will the 2ltr mix have the samd reading as 12ltrs if i use the same nute ratios? I'm asking if based on what I've got right now, can i up my nutes slighty or add a supplement like terpene enhancers without changing my main mix ratio too much or at all. Am i on the right track?

ah, i have instructions in that shared spreadsheet -- show comment in A1 -- W%/W requires a specific gravity calculation. my spreadsheet may or may not do it correctly, lol... does the other stuff fine.

Google 'nutrient ppm calculator' -- make sure it can handle specific gravity, depending on labels. (w%/v, i believe?, if dry nutes or no need to consider specific gravity .. i got a link for a spreadsheet if you want it...) Use info from your guaranteed analysis labels to calculate elemental ppm. whether the online calc or the spreadsheet, it'll spit out the values. Knowing the ballpark of a balance mix is useful information. Once you have a recipe you like, calculate again and you'll always know roughly what it is even with minor adjustments for picky plants. Don't really have to recalculate as long as you stay in that neighborhood after that point. i have a table that is a >650 ppm mix - can see in any but oldest diaries of mine. i have hard water. so u likely need more ca, mg, s than i use. When i go higher i run into issues, but most likely due to my water. Find that balance relative to your environment and life gets easy. https://drive.google.com/file/d/1jZs2lXuZOS6HhTBl5jInBt0jPnMhJa2Q/view?usp=sharing

950 is to high for hydroponics. 800 is about max for most photos period plants and 600 is about max for autos when growing hydroponics.
