Coco grow what PPM

[Stblazed]

Hi!

I got 4 sensi sensi skunk fems on the go (I day 4 1 is different strain for sure leaves look like duck feet!).

I had some trouble with nute burn and a broken PH meter which I have now overcome and plants are growing normally again!

I have just purchased a PPM meter and wanted to know what PPM I should be using? my plants are 16 days old and I'm using canna coco with 10% perlite canna a+b 1/4 strength.
My tap water is PH 7.5 reading 199PPM.
I've been feeding them PH 5.8 tap water with weak nutes, rhizotonic and every 3rd feed 1ml of calmag.

I've been told PPM 300 for how young they are does that sound about right?

I had a buddy that went off to grow for some guys in Oregon that said they swore by dina gro foliage pro/mag pro/protekt at 350 ppm all the way through in promix. Everything you read from people says to gradually increase every week until you're close to or over 1000ppm. In the end you just have to understand and read your plants to know if they want more or less. And understand your medium, some like more of one thing than others (coco usually likes more calcium than other mediums), and if you're in something like ffof you'll just be supplemental feeding at extremely low ppms.

What I like to do in coco is start low. I use DG foliage pro 9-3-6 (or DG grow 7-9-5), DG protekt (potassium silicate), and any kind of liquid cal-mag. I usually start with 1/4 tsp/gal of each in DI or RO water, when I used tap water I didn't use cal-mag, just occasional Epsom salt. Then watch them over the next several days. See any yellowing? Any tip burn? Adjust accordingly. Keep increasing the dose of your primary nutrient (not the silicate as it will require you to use pH down which I try to avoid) and the cal-mag until you see tip burn, then skip the next feeding and just give it straight water. Then dial it back to the point right before the tip burn. From my experience, this new found nutrient concentration should keep the plant happy all the way till harvest (being sure to give it straight water between feedings to remove buildup).

I'm sure that plenty of people out there have better equipment and more experience that me. But once I finally ditched the idea that I should be at "X PPMs" by a given week I began seeing the results I was looking for, and with a lot less effort. Just watch you're plants, how much they grow each day (which is easy to do with t5's), and how they look. Every plant is different, even 2 seeds of the same strain, and one thing usually won't work for the whole population.

I used to follow the guide with light feed schedule, did fine, but I found you can cut it in half or say 2 3rds and get less problems with salt build up and still get the same results.

You will get more from a plant slightly under feeding than over feeding.

Great reply thanks! I just needed a number so I'm not going to burn them to hard. I would always want to use as little nutes as possible as I think less chemicals is always a good thing.
I'll let you know how they respond

yep your good, 550-600 ppm by end of veg 900-1100 ( depending on amount of light and if there is co2 enrichment) by mid flower. then slowly taper off

 

[upnsmoke13]

I'm using a&b with cal-mag, plan on topping out at around 900 ppm mid-flower. Stretch was over early this week & went up to 700 ppm this nute batch. Vegged between 4-500, nothing burnt maybe a lil light!

Should be feeding everyday in coco not feed water feed water
