Up base nutes or add calmag in coco

with no runoff you have to worry aboutbuild up of nutes in substrate.. so just keep an eye on any creeping "overly-lush" look to them or other toxicity issues. maybe1.2-1.3EC would be a better starting point than 1.3-1.5 -- i'd start out mimicing what they suggest for no runoff with frequent fertigation. trial and error will get you there quickly from that point. Regardless, calcium is something that needs to be included in every fertigation at a certain proportion of total and certain concentration. It's not something you add randomly or occasionally. All the primary, secondary, and trace nurients should be included in every fertigation. whether you use coco or a different soilless substrate does not impact this. if it does, it's poorly processed coco that is not buffered properly. Your tap water will be minor differences. you may need 5-10% more or less than others of ca or mg. The insctructions for cellular reproduction, aka growth, does not have an "IF coco" insctruction.. it doesn't give a shit if its roots are in coco or not as far as feeding concerns. The parts of cells these building blocks are used for are not made differently based on substrate. Cell walls are still cell walls and constructed in same manner by the plant.

Im using autopots so no run off. Tap water plus 100ppm of calmag 1.4 mil per litre a 1.4mol per litre b Takes ec to 1.4. Do t really wana go over that in bottom fed system. Not much wrigle room for boost or pk with out ec going up

Depends on your tap water . If it's soft water around 0.1/0.2 then add calmag up to 0.4/0.5 EC. Coco uses calmag as a buffer so it's good to feed with it everytime. Seedlings Magne cal plus 0.5ml per litre Canna a 1ml per litre Canna b 1ml per litre VEG magne cal plus 0.5 ml per litre Canna a 1.5ml to 2 ml per litre Canna b 1.5ml to 2ml let litre. Some plants can take more some can take less a and b. So always read the colour of your plants pH you want to feed at 5.8 in flower I go to 6.0 Runn off ph should be around 5.9 to 6.5 and your in the zone. 6.3 run off ideally .

none of those factors affect how much Ca you should provide. In a soilless context, if you aren't around 100ppm or more of Ca, you need more. Simple as that. If your tap water is very hard, you may need less. Trial and errror is the only way to figure this out in each individual garden without an accurate water analysis report. Even then, you still need to do some trial and error to learn what is needed. Whether in coco or any other soilless context, the plant needs roughly 100ppm Ca in a 1.3-1.5EC concentration of nutrients. You need to fertilize every time with 10% runoff waste. Remove waste water. Do not let a plant sit in its own piss. That waste water can be used on plants in the grond outside, but should not be used for any potted plant. The medium the plant sits in does not in any way change the calcium needs of that plant. (excludes poorly buffered coco contexts, because that is a failing of the manufacturer) If it does, that is a sign of shit-ass coco that isn't buffered properly. This is the negative of coco coir. If not processed properly it can wreak havoc on the balance of fertilizers given until it reaches an equilibrium in the CES relative to what you are feeding. This can take a month or more and in the mean time plants may die, especially if heavy in Na+. well-processed coco is safe, but it is not magical. it does not result in faster growth. That is caused by the soilles/hydro nutes you use. 100% soluble and 100% chelated nutes provide for faster growth and fertigation methods vs soil. Any medium with proper drainage qualities and aeration qualities will perform just as good, all other factors the same. building blocks are mostly needed in same ratios at all times.. it's not a "add some of this this week and some of that next week" kinda thing.. that sort of behaviour will ony lead to greater frequency of issues than necessary. There is no rason to play "mad scientist" with your formula. 1-1-2 NPK ratio // 4-2-1 K-Ca-Mg ratio -- weighted average of your labels relative to dose can be compared to these. These are not meant in an absolute way. e.g. i think my npk weighted average is 8.2-8.9-14.7? i have a spreadsheet that keeps track. I started off tracking ppms and trial and error lead me to the same place reseach pointed toward - not coincidentally. Unfortunately, i didn't find that knowledge about ratios until more recently. You can google this stuff and read for yourself too. Avoid "marijuana" sites, lol.. you can see this research in action across several brands and products -- competent, professional Ag sources. JAcks, southern ag, masterblend etc all have heir "version" that is only slightly different in meaningles ways between each other. Maybe one is 5-12-26 base or 6-13-27 or maybe they put the trace elements in the calcium nitrate to force you to buy 'their' calcium nitrate, etc. Anyway, this will usually be dry nutes and paired with calcium nitrate and optionally magnesium sulfate (epsom). Even floraflex has a grotexquest overpriced "pro" line that mimics this research... old existingknowlege based on samples sizes and even across similar species of flowering plants. Proven, perr-reviewed and consistent... the last one is the key... Consistency. This formula doesn't just "work" it will work on 95% of anything you put in front of it. 10 strains off one reservoir? that makes some people sweat, but is no problem whatsover with a good formula. People who think this plant is picky or needs all sorts of adjustments per strain and this or that... that's more a reflection of an imbalanced formula that needs severe adjustments because not all plants can handle the out of proportion nutes provided the same way.. that is what causes the volatilty in results and why someone might think oh these plants need drastically different things.. they don't.. .if they do it's a genetic abomination caused by a poor selection process that shouldn't have been bred, lol. Avoid "mariuana" sites in general. One bastion of rational thought is dr photons corner on cocoforcannabis website. they are usually rife with shit information basedon what was repeated more and more loudly by the peanut gallery than actual evidence... often rebranding existing knowledge as new and misinterpreting or applying it in some unsophisticated way. New vocab for things that were already understood is a big one, lol.. just a sign the prevailing of ignorance, lol. Anoter excellent example of profoundly wrong thigns being repeated -- "A marijuana plant in flower needs little to no nitrogen." Bullshit.. false.. overtly false, proven false, absolutely absurd... yet, large proportions of people believe such a retarded thing. Cellular reproduction needs nitrogen for many many things not related to leaf production and stem elongaction (aka "vegetative" growth). DNA has N in it.. how does a plant properly reproduce any cell if N is hard to find? LOL... organelles use it, maybe hormones? all sorts of molecules necessary for plant biologiy require N. it is a blatant diregard for existing generational knowledge to say such a thing... knolwedge based on actual evidence and verification processes that are self-correcting, LOL... not anecdotal nonsense of uncle enis based on his drunken fumblings around a garden.

If growing in Coco you wanna make sure you supplement with calmag
