ppm

I grow in DWC hydroponics. I have been finding recently that no matter the PPM that goes into my reservoir, I have to add water every so often to keep it down in the ideal range. I am very interested in why this happens, if it has something to do with nutrient quality/type, salt/nutrient build...

High Guys I have a question. I've had quiet some time growing in soil and it all went fine. I switched to hydro about a year ago with well... Ok results. Pulled around 300-350g on 4x4 with 400 watts. I am using the Lucas Fomula on RO water with Cal/Mg to EC 0.2 Top feed with clay pebbles...

Sup !! I'm wondering if you guys out there could chime in with your solutions to hard water fixes . It’s come to the point where I have to sort out my water situation As I’m getting lock out with touchy strains . Do you have good experiences with Any easy quick fit RO systems out there ? Maybe...

i got a high ppm/ec read on one of my plants run off water. I did only one feed of Athena blended and it was 600 going in. They are a little droopy and I thought it was from over watering but could it be from them having to much nutrients built up in the soil? Should I flush with pure ph’d water...

Hi all, long time lurker first time poster. I'm trying to figure out if there is a way to within reason calculate the EC (or PPM, TDS, whatever flavor you may choose) of a nutrient product based off it's label composition & reported SG/Density (mostly gotten from MSDS info). (I understand this...

So I’ve got an approx 25-30gal RDWC that houses up to 4 plants and I’ve never once seen my EC levels go down over time no matter how little I feed and what I set them at. 4 weeks into flowering and I can barely feed at 1.0 EC (500 ppm) and it will end up holding steady as water levels go down...

white widow second generation day 87 Happy frog medium No nutes yet Temps at average 68 degrees 65% humidity Runoff ph 6.32 Ppm 810 I am trying to figure out why the leaves seem so yellow? Any advise?

generally use good water at 50ppm or less but for goofs used some very hard water. 1000ppm to 1700ppm. used same nutes in both with exception of no cal-mag in hard water. the hard stuff yielded some very hard stuff in a side x side. the usual is light n not too solid, the experiment made a...

I'll keep this brief. I read that some hydro growers don't go past 1.2 EC when it comes to nutrients at full bloom. So assuming you are using tap water, do you measure 1.2 EC of nutrients plus the EC of the tap water (example 0.4 EC tap + 1.2 nutrients = 1.6 EC)? Or is it more important to not...

My plants are all suffering from something I cannot figure out, leaves are turning shiny on top, new growth is shiny, rough, and clawed. New growth stems are short and stunted. I have not fed ANY nutrients thus far JUST Soil with .25-.06-.12 levels. Added CAL-MAG Calcium magnesium and iron...

Hi everyone , I'm a newbie so so I'm hoping I can get some guidance. I'm growing one gorilla glue and two blueberry auto flower plants . They are in 2 1/2 gallon air pots and growing in fox farm ocean forest potting soil. I'm also feeding the plants fox farm big bloom , tiger bloom and microbe...

This is my 3rd grow, I don’t know why it took so long to check my ph & ppm but I am finally doing it. The buds are small and haven’t really been growing. I been just watering my plant with ph’d water to fix the ph and bring the ppm down. I’ll attach imagines of the reading throughout the past...

(Not sure where to post, my apologies if it’s not the correct section.) So long story short, my father’s asking me to help with his lawn care business, and we have a few problem lawns we need to troubleshoot. What would you recommend for proper equipment? I’ve heard 50-50 reviews on blue labs...

Hey guys, thanks for reading! This is my first ever fully coco run. I'm using botanicare nutrients and FloraFlex lines. Two plants (of 6) left. One is showing what I think to be a really bad nitrogen toxicity, the leaf ends are very curled under and some are slightly burnt. The other plant is...

I’m on week 6 of a 9-10 week strain. I’ve heard people say you don’t really want to go above 700. But I’ve also heard people say they’re using 1000+ ppm. (Using .5 conversion chart, same as me). I’m giving my plants plenty of phosphorus and potassium, but still seeing deficiencies. My PH is in...

Hello, If a plant only has normal CO2 (300-400ppm) during every stage up until flowering will additional CO2 (1500ppm) during the flowering stage even be worth it? Will it just kill the plant, not have any affect, or will it in fact still be worth it? Thank you!

Hello all, My last grow, I only used GHE Flora Series on and Atami Wilma dripper system with clay pebbles. I had a good yield, but now, after 7 years, I've set up a better system, using the same dripper but changed to Terra Aquatica TriPart Series (new brand for GHE), with additional...

Title says it all.. planted seeds into happy frog.. plants look OK 2 are fine 3 are ok showing different issues. But I have NEVER fed anything to these plants... just water... I always phd it at 6.5 and before I even planted the seeds I watered the soil heavy to try and lose some nutes.. what...

Hi Spotted this, www.pavunversooulu.fi/category/66/ravinnelaskuri Click on the tiny link titled "English" for the non-moon language version. Tried it with GHE nutes and ended up with 0.5 ec solution, which was spot on. Does anyone have the other nutrients to try and see if it's accurate?
