cant helo you with that but sure someone on here can but like i said that correct ppm really depends on strain most strains the grower i know grows can handle 1700ppm in flower no prob
High PPM BS!!!

I understand a Cannabis Sativa wand at 11 inches with a krypton particle core makes the best growing wand in the world>

i can give my plants up to 1300 ppm in veg stage and i get slight burn and some not at all and all showed vigorus growth and i think genetics have to do with how much each plant can take some strains more nues thatn otheres but i gradually get it up there i around week 3 of veg i use advanced nutrients organics the full line i dont mind paying extra

Depends a whole lot on your rate of transpiration. That depends a whole lot on your humidity, then your temp, lighting and CO2 level. Different parameters allow for different EC levels without burning. If you run excessive humidity like many reccomend you will have little transpiration. Little transpiration will mean little nutrient uptake. Of course that would also mean less growth. If you have a lot of transpiration high lighting and CO2 or constant ventilation and low to moderate humidity then a high EC wil ac cause burns because you will have a high reanspiration and there fore a high nutrient up take. ie a well managed high parameter grow with midrange or lower humidity requires lower EC nutrients but increased water usage. Pretty simple.

It comes down to strain.. and your ppm meter might be different.. some have .5 coversions and others have .7
the meter reads the EC and converts it to ppm for you
now one's gonna read higher then the other because of the conversion factors. EC is the universal language.. and I believe the true conversion is .64

I typically do not like to go any higher than 1500... it is at this point my two bagseeds seem to do the best, and typically use the nutes to the tune of 100ppm or so. just tells me the plants are using the vittles.
Any time it goes above 1500, i get nute burn. So far, every time.

You know.... in my experience my PPM start at 250 and end at 2200 and EC @3.3 strains are Sundae Driver and King Louie. Yeah you have some of the foliage on some plants have some problem within the structure about 2 to 3 big fan leaves and that's about it nothing crazy just my input on our run to date week 7 flower .....

I'm coming to an end of a Sensi seeds NL grow. What are you asking? What PPM? It's different during each start of the grow. It went up to 1500 fourth week of flowering - now its down to less that 1000 for the last 2 weeks, as its finishing off.
2000 or 3000 is mental - I have never even been close to that. Putting aside the damage to the plants, its got to be quite expensive to run at that high a level, as I would imagine you'd need a fair bit of nutrients,

Different strains take different levels. Also different phenotypes will also have different nutrient requirements, It not as simple as this strain needs this amount. Be easier if it did, but in my experience, it doesn't work like that.

i did maybe the fifth week of flower at 1000 rest was all 900 or less. or i get slight burning.

You must be using RO water to get those low figures though, right?

No, my tap water is around 110. I use masterblend mix.recept is around 600ppm i add a little bit more
