For thsoe of you using R/O... I am very surprised at how fast my filters are being used up. Brand new it was 10-20ppm..I'm at ~100ppm on a 270ppm city water system now. And I'm NOT a big user.

I replaced my filters with cheapos off the zon or ebay and they've stayed at 0 for a long time I probably have over 5000 gallons thru them since then. its got 6 different filters, 3 big membranes. Mines been at 250 or higher otherwise.

Appreciate the info! Cant wait to give this a try. Makes so much sense vs paying for water.

Bless up to everybody for all this info and especially to Bill where ever you are!

I am under LED in coco. Been under a week since flip and was vegging under hps. Now I have gone from nice green to yellowing inside of top growth. I believe it is Ca deficiency. Should I add Cal Nit or Cal mag and how much per gallon? Appreciate it to the max!

Trinity
full


feeding the following
RO
~60ppm epsom salt
Jacks 321
mr fulvic 1ml/gal
Ec 1.4
Ph 6.0

that's crazy I do like half that much mr fulvic at ~6.0 every other and it always looks a bit hot like they're almost getting burnt and I do 221 masterblend, I also do 1/4tsp or 1.2ml per gallon potassium silicate on those mixes

I have been using the mr fulvic with feed for the last 2 years. I just last week read that bill was recommending using it soley as a drench weekly. I don't think thats it. The HPS tent is a bit pale too so maybe I need to add cal mag??

I am also running Silica Blast at 4ml/gal but also something I have been doing w canna, so I dont think thats it. I was afraid of going from 1.2 to 1.4 but they didnt seem like they were hurting. I have heard others running LED that they were feeding way more too. I know my last run was holding nutes even though I had run off.

Last time w canna I was feeding 1.2 and checked runoff at 4w bloom and was getting 2.7ec so maybe I should increase the ec and water longer. They are on drip as I dont have the time to hand water and am frequently away for a week or more. The Jacks is cheap so no issue running more fluid through them if need be just need to know where to start out without burning them up.

Thank you everyone!

I'm in coco hempys and hand water with tap, in 1 gallon buckets maybe 80% full I feed ~32oz for normal runoff with nutes and with fresh water an extra ~16oz for a routine flush when I mix new nutes

My understanding has been that temps play a role in cal/mag deficiency, especially with coco and Leds. HPS/MH usually produce more heat so the symptoms stay back, even with coco. Just something to look into. Looks healthy to me.

Never fails, folks overthinking this and screw up their gardens with all kinds of make believe cause and effect stuff.
Never fails someone chimes in with a vague un useful comment that makes the OP play even more guessing games.

I believe they needed a higher ec. I was under the 321 recommendation for full strength. I normally dont run so high of an ec. I upped it to 1.4 and increased time on drip and they look better.

Prior to jacks I know that I was getting buildup as I was feeding 1.2 but they were darker green and runoff was always testing higher than input ie 2.4-2.7 but not usually higher and no tip burn. The look better now but will have to keep up with this and probably keep ramping up the ec over the next couple of weeks.

I did add 60ppm calmag plus just to see as it has iron as well but just a bit.

You're fishing, and over thinking this.

If you're doing water culture or soil, it's hard to beat Dyna-Gro. As my thread shows I like Osmocote. 1 part, complete nutrition at a reasonable price. Cannabis specific foods suck.

When I am consulting, I get asked for a complete but cheap nutrient lineup that is suitable for commercial usage. This lineup can also be scaled for the home grower to save some serious cash.

You start with a salt base nutrient. Jack's classic hydro, Masterblend, Jack's Nutrients TAP or Growmore soluble powders also work depending on your access.

Jack’s Hydro Feed- 25 lb bag
$70- 2000 gallons
$0.035/gallon

Add your biostimulant. Mr. Fulvic is the home and garden version and has fulvic, amino and organic acids, chelated micros and trace elements. AGT-50 is the commercial wholesale version. They both help make nutrients available regardless of pH and give salts organic taste and smell.

AGT-50- 20L
$460- 20,000 gallons
$0.023/gallon

Extra calcium is needed at transition. Growmore Flowering Cal-Mag also has kelp to help stack nodes going into flower. Albion metalosate and epsom salt can also be used.

Growmore flowering cal-mag- 2.5 gal
$90- 1900 gallons
$0.047/gallon

PH down is pH control, but also adds soluble phosphorus when something like HydroFeed is low in Phosphorus.

Advanced pH down- 4L
$82- 6600 gallons
$0.01/gallon

For IPM, insecticidal soap will take care of bugs and mold.

DES-X Insecticidal Soap- 2.5 g
$85- 300 gallons (@1%)
$0.28.3/gal.

For a bloom booster, Monopotassium phosphate used weeks 4-6 of flower.

Haifa MKP- 4 lb
$20- 1820 gallons
$0.01/gallon

This is a complete lineup including IPM. It can be used large or small. There's no reason to spend a ton of money on fertilizer for excellent quality cannabis.



I have a thread in the Ace forum called farmerlion's;just a grow, yah know. I cover fungal repositories and how plants eat. This can be done for home grows and commercial operations.
The quality of the harvested buds is outstanding. In the advanced growing Sciences forum I have a detailed thread called Making Marijuana Great Again.
I hope you find these tested and proven techniques helpful.
Peace farmerlion

Hey guys, I'm new here and I only have access to the masterblend's 4-18-38/epsom salt/calnit set. I've read all 32 pages of this thread and now I'm even more confused lol. Should I just follow MB's instructions just to keep things simple or is there a better alternate ratio that even a novice like me could follow?

Sorry for the confusion friend. The important thing is that the EC remains consistent without fluctuations. Keep constant feed going with the appropriate ppm. If you need help go to the help forum and start from scratch. I will be glad to help you.

Can I use osmocote on tomatoes? I wanna practice on growing tomatoes first before I start growing cannabis.

Sure, it's probably made for tomatoes more than it is made for weed. And the 2 plants have quite similar needs, generally.

Get some hemp seeds from the pet shop. Somewhere specialising in bird feeds, as you can usually buy the individual seeds, to blend your own bird food. Health food shops also carry them, as hipsters like to nibble.

You've fallen for the cannabis hype. There are NO special needs for weed.

All you need is a good hit of Osmocote Indoor-Outdoor Plus and watering can. Start to finish.
