i have never gotten a good answer to this common question. my meter is tds ez from HM digital, it doesnt list a "conversion factor"
Week 8 Flower Still SMALL BUDS!!!!

I have the same one! Not sure either... can anyone answer that for us?
Mine is the HM Digital Aquapro

I have a 20 yo Hanna ppm pen that still works great. It does tend to wander off so a quick dip in calibration sol'n keeps it on track. Buy the ready made sol'n tho as the powdered stuff that comes with some pens can be quite a bit off it's stated ppm. This chart comes in handy when discussing ppm with people that use different types or EC. Just the right size to print out.

When I looked it up it shows the conversion from E.C. To TDS to be NaCl (avg. 0.5)

Click the link in my sig and scroll thru and see yourself. It's under a 600w light, so I better be pulling at least 13oz.
20oz was Original Amnesia, took 15 weeks to flower so kinda sucked I had to wait so long.
13oz is easy, if i get less than that I'm doing something wrong. LSD pulled that.
Another one in my post is 15oz, ran two strains that time. 9oz Blue Mystic and 6oz Great White Shark.
Feel free to ask any questions in my grow journal thread.

Thanks for the post! I am probably due for a recalibration. I just happen to have some calibration liquid laying around...View attachment 3897377

I looked yours up and it uses the 0.5 conversion so you would use the Hanna #s for your readings.

Temperature Range: 0-80 °C; 32-176 °F
Resolution: 1 ppm
Temperature Resolution: 0.1 °C/F
Accuracy: +/- 2%
EC-to-TDS Conversion Factor: NaCl (avg. 0.5)
Calibration: Digital calibration by push button.
Housing: Water-resistant
Power source: 1 x 3V button cell (included) (model CR2032)
Dimensions: 15 x 2.8 x 1.3 cm (5.9 x 1.1 x .5 inches)

I read through your scrOG journal... some serious buds in that one! I was thinking about running a DWC scrOG for my next grow... maybe just leaving one plant to fill the 3X3 tent. Also let's me focus my energy on one plant instead of juggling 4 different buckets

I actually have that same one I bought for making colloidal silver as it has 1ppm resolution and my old Hanna is 10ppm increments. Seems like a good pen and has kept it's calibration dead on since I got it. I diluted 1000ppm calibration sol'n down to 20ppm and it reads 19 in that so it's close enough.
It uses the same 0.5 conversion as the Hanna.

Yeah def a good way to go, especially to learn everything and dial shit in. Yeah juggling all those buckets sucks, that's why I went to just a single res for my multi plant grows. I'd say do a solid 6 week veg with a single plant and scrog that girl up and you'll be real happy with the end result. I actually have a buddy on here that grows the same style as me but he used to use a 400w and now just got a 315w cmh. He just finished his first 315w grow and pulled 10oz, he had a lot of PH issues though because he was away on work a lot so it wasn't the best grow, so you could def do better than 10oz, strain dependent of course.

I've got a blulab combo meter. It's about 5 years old. I never read the instructions or looked for a conversation factor. My motto is the kiss method (Keep It Simple Stupid). I can switch back and forth between EC/500 scale/700 scale. So I can't help you. Somewhere on the box or paperwork should CLEARLY state which scale your meter is on. I'd hope anyway! That said I haven't run across anything I've used that needed to be measured in anything but 500 scale. So if I had to guess I'd say your meter is lower end than mine and only reads in 500. But that's a guess.

Don't forget that the nute companies may use either conversion factor on their directions.
Botanicare lists ec on their directions but at a 7 conversion instead of 5. Which is strange because in America we use .5 to convert ppms.
On a water test for example .4 ec is always 200ppm.

I feel from the pictures of dark green foliage on page 1 that u suffered some over-fertilization which is a well known plant stressor and just stunts them girls...some bounce back others don't..TBH they def look like a little too much Nitrogen,but def could be 2 much on the girls..I feel based off ur pics and my opinion,that the girls have another 2 to 3 weeks till the chop- block..Did u take any clones?would be nice to run those girls back again,and see for urself how they are better and better every grow..plus those r fire genetics imo,,I use NFTG Herculean Harvest for mid-flower flush and end flush last 2 weeks..works great and like a charm..honestly,,water ph'd does wonders,but something about tht HH that binds to them salts,and uses them up...Just my 2 cents homie,,,hopefully something I said helps,and if not then its still cool to talk some shit about growing Cannabis lol...
much love and peace and keep us posted ,,I am def interested in how things are coming along

I have been growing for a long time and can usually get over 3lbs per plant (dry) in RDWC 1000w each light with my genetics. (No Co2) With different genetics I can get vastly different numbers such as (1.58lbs vs 3lbs 3oz). (Real numbers). So my take on yeild is what genetics you use. Light plays an important role as well. As in 30 watts per square foot vs 50w. Finally how you train them and veg times also will effect yields. Then boosters/hormones lastly.

Thanks brotha! I appreciated the feedback. I wish I had kept clones those girls. I am gonna be growing just 1 GDP as a scrOG on my next grow... hopefully I can dial it in a little better next run.I feel from the pictures of dark green foliage on page 1 that u suffered some over-fertilization which is a well known plant stressor and just stunts them girls...some bounce back others don't..TBH they def look like a little too much Nitrogen,but def could be 2 much on the girls..I feel based off ur pics and my opinion,that the girls have another 2 to 3 weeks till the chop- block..Did u take any clones?would be nice to run those girls back again,and see for urself how they are better and better every grow..plus those r fire genetics imo,,I use NFTG Herculean Harvest for mid-flower flush and end flush last 2 weeks..works great and like a charm..honestly,,water ph'd does wonders,but something about tht HH that binds to them salts,and uses them up...Just my 2 cents homie,,,hopefully something I said helps,and if not then its still cool to talk some shit about growing Cannabis lol...

Were you basing the 2 to 3 weeks on the first on second set of images I posted?

Thanks for your your 2 cents. Im still getting my head wrapped around all the different things that go into a solid grow... but I guess thats what your first grow is all about, right?

Here are some key notes.
In the flower stage, earlier in the first 2 to 3 weeks run a little "Cal Mag" with your regular fertilizer schedule.
Keep humidity below 40-45% more so in the late flowering period. Important!
Temperatures at night should be over 68
Keep daytime temps under 80
Keep your reservoir water temps at 68 or lower but no less then 60.
Run fans over and under the canopies
String up your branches to ease the weight of the branch to encourage more robust bud development.
Make certain the water level under the potted nets is 2 inches give or take, below the basket.
PH should hover around 5.8 to 6.0 and no less then 5.5 for too long in flowering. 6.3pH in veg.
SM90 to prevent or stop pathogens in the water.
LST HST topping and FIM will dramatically improve yields.
Best of luck my friend !

i also think something went wrong along the way, probably the time you went away for a week.
the curled up leaves and brown edges show nutrient toxicity, and if this lasted for long time it may have impacted the overall bud production.
overall the buds are not small, considering you could go 2-3 more weeks of flowering easily. i guess plants were quite small as well when you put them into flowering due to space limitations.

Yeah,,, I definitely had some nutrient burn along the way. I actually veg'd them for about 6 weeks so it wasn't too short. You live and learn... I'm excited to get the next run going
