nutrient problem in coco

first time using coco so many issues allready please help

Whats your feeding schedule?, ph?, type water using?, how old is plant?....all that

plants just 2.5 weeks Im on a 3 step feeding as suggested by my hydro shop day 1 feed day 2 water day 3 nothing its ph to 5.5 and im using distilled water as I do not have an r.o system

im also using canna coco fert at 1/4 strength

try bumping up the ph a bit....to see if the lower ph is blocking nute intake

so like 5.7 5.8 ish ??

yes no more then 6. Are you checking runnoff?

ya thats the thing run off is comming out a 5.7 and in at 5.5 so if I bump it to 5.7 in im estimating close to 6.0 coming out ... should I proceed to a full flush with 5.5 untill runnoff is 5.5 even and then maybe start with maybe 1/8 strength

Im not sure why ppl go at 1/4 or 1/2 strength nutes..... feed them suckers, they are heavy eaters and in coco you have all control of the food.

this sounds good... feed more tho

ok im gunma do that then feed with 3/4 strength and then move up to full strength if I see good results

thanks for the input ill be posting the results in a few days

cool, I'll be watchin. GL

Get some perlite in that soil. Need to let the medium breathe. What is your ppm? Are you supplementing calmag?

u see I was told not to use perlite woth cannacoco I asked but considering I thot I should listen to the guy at the hydro store I am suplementing calmag and my ec is at 1.2

Coco is an entirely different type of medium from soil and does not need to be cut with perlite as it does not need additional aeration to maintain proper oxygen levels at the root zone. It does appear that he started the plant in a larger container than he maybe should have, however. Even though it is really hard to overwater coco if the plant has a solid root system, it is definitely possible and easy to overwater a young plant, especially in a larger container.

Checking runoff is really unnecessarily 99% of the time and it's just going to confuse you further. If you are going to check run-off, make sure you do a slurry test and don't just use the liquid. It's really not necessary most of the time, though, so check your pH and EC going in and try to keep it in the 5.7-6.2 range and around 1-1.2 EC at maximum. If you have an established root system and are not simply overwatering the medium, start hitting it with full strength nutes at the recommended levels to begin with (15ml/gal if you are using Canna A + B) to about 10% runoff and monitor your progress. You should see an almost immediate improvement if you are on the right track.

Cal Mag is not typically going to be necessary unless you are using R/O water, as most coco-specific nutrients have plenty of both to accommodate the medium they are intended for.


I would refrain from adding anything else to the mix until you ascertain exactly what the issue is, and in my experience the best way to do that is to "reset" the medium by using a complete solution (in this case, A + B together) without additional additives. Sometimes in a plant with a well-established root system, you might want to "flush" to 100%+ runoff -- but no matter what you do, never put plain water through coco.

Honestly, the plant doesn't look very happy, but it also isn't necessarily screaming for a solution quite yet. Again, if you are using R/O water instead of the recommended tapwater for the Canna line, you may need to think about cal/mag -- right now I don't see any indication that you have any issue serious enough to try to correct by dumping new ingredients into the mix as of yet.

Hope that gets you on the right track.

Are you using tapwater or R/O water?

I acctually dont have a tds meter ive always used ec its just what Im used to and for me its simple

thanks u lawlrus I feel like that makes more sense

That's actually ideal, EC is the more accurate and universal measurement as it does not have different scales as PPM does.

tapwater but I have been letting it sit for a few days b4 hand
