Yeah, should have provided more information.
I am using advnaced ph perfect micro, grow and bloom as a base. Growing medium is canna coco professional plus, currently using a phlizon 600W which puts out 115W. Water is from the tap at around 8PH and 32PPM. Using fabric 2 gal pots.
When I was mixing earlier on today for 3L of water i used 1.5ml of each base and 3ml of VJ and b52. This is half what the AN calc suggested and came to 220PPM. Plant is still seedling working on its third set of true leaves. Based on the fertigation guide at coco for cannabis it suggest the range of PPM for seedling as 200 to 250.
My question was a bit dumb because I know in order to adjust PPM you add or detract the nutrients. I'm just not sure whether to keep the ratios of nutes the same as the AN calculator and just add less to get the desired PPM or if I should be altering anything.
Maybe I shouldn't of even started them on nutes this early.
When using coco or any other soilless media you have to feed them right from the start or they starve. Sound like decent levels of nutes but I wonder about the tap water. At only 32ppm it seems strange that it's pH 8. My tap water comes out of a dugout on my property and it's pH 8+ and around 400ppm so I never use it and buy RO water for drinking and my plants. I tried coco almost 20 years ago and it totally screwed my plants but was most likely my fault and crappy coco that came in a brick. Not unlike the first kind of pot I got way back when.
Generally when speaking of nute amounts it's best to say ml/L and GMB for Grow, Micro, Bloom. So if saying I'm using a 1:1:1 ratio I'm using the same amount of each tho once plants are vegging well I switch to a 3:2:1 ratio of GMB then in flower after veg go to a Lucas Formula style of feeding using a ratio of 0:1:2. From practise I know that using 1ml/L of all 3 base nutes I'll have approx. 300ppm which is what I start DWC clones at or even seedlings. Each nute doesn't make 100ppm tho with Micro being the highest. I have notes about my testing around here somewhere but can't seem to find them atm.
One thing about coco is that it needs extra CalMag right from the start. You should do a search in the forums for info about that but from what I've read users soak it in extra calmag before use to get it going right. Multiple waterings per day are also recommended and those are reasons I have no desire to use it. Cost and availability are a couple others. I'm in the boondocks here and the nearest source is 2 hours away and 3X the price of ProMix HP which I can get in town. Shipping is not an option and would triple the price again. The nearest hydro store is where I would get coco too.
You can find good info in the following link too.
I found a great spot to download
FREE POT BOOKS . I downloaded a grow bible first and got lots more. Books look great and complete like the real ones I have here. No web site but just a page of links. Just right click on what you want and then "Save Link As" to download so they don't open first as many are 50+ megs. They got lots. Enjoy.
