1 tsp/gal of CalMag is 5ml/gal. Way too much and again it's not needed despite what you've read. Leaf issues are NOT common with early veg, despite where ever you read that. I'd assume it was the same place that told you to use CalMag.

It sounds like the runoff doesn't stay in the saucer and in contact with the cloth pots, at least that's good.

In addition to what I already suggested I would suggest using the manufacturer's suggested feeding schedule, but probably the light feed schedule. Where did you come up with 2.25 ml Micro, 2.25 ml Gro, and 0.6 ml of Bloom?? If you wanted to get 1.2 EC the recommended light feed schedule is 4.9 ml/gal of Micro, 4.6 ml/gal of Gro, and 3.4 ml/gal of Bloom.

Also notice the manufacturer of your nutrients doesn't have CalMag listed? There's a reason for that, the nutrients already contain calcium and magnesium in sufficient quantities.

once again i made an oversite and am just now seeing this and comparing to what I was following, wow. so yeah I am using this as a base nutrient reciepe and a couple different ones on two plants until more come. I am guessing the week 4 is just continued until you flip to bloom right? for photoperiod? and then calmg 1ml to 2 ml if i see calmg issues which many are implying I won’t. thanks for this tip! propably are deficiencies from all other nutrients like a few said. and then maybe water twice in veg to avoid ph issues in rootzone.

The thing about CalMag, is that it usually also has a lot of N, so it will throw off your whole NPK ratio. It might not be an issue in veg, but in flower, you would be feeding more N than desired.

If I were you I'd stick to EC around 1.3 to 1.4, and adjust in the plant tells you to. Forget all the extra enhancements like bud candy or whatever. If you do add anything additional, I'd suggest a kelp product and fulvic acid. I think you were adding like 5 ml of CalMag if I remember correctly, which is like 2.5x to 5x more than they suggest for lucas. Personally I run Jacks 321, and never add CalMag, because that formula already has a lot of both Calcium and Magnesium.

sorry, miscommunication, I meant adding any calmg compared to none at all, some were saying not to. what is helpful about that lucas webpage is it at least specifies to use only as needed so you dont think its essential.


but what i was doing I am seeing was dumb, shorting them on base nutes. but the schedule from mj coco does go to 2ml calmg after some point of vegging. perhaps the first part of their schedule is conflictive with many and the rest of schedule being determined as underfeeding by many (tops at 1.2) so i felt high.

but after this thread I can confidently sewitch things up and up the nutrients, keeping RO water and no calmg to realllly open space for nutes.

talk about over complicating shit its a weed dude feed it it will grow , so much bro crap from companys that supply nutrients to hook the new and miss in formed growers to buy products ....
your going round in circles chasing your tail - keep it simple :eyesmoke: :bigjoint:

Why are you worried about runoff in coco? This measuring runoff stuff is getting ridiculous. Just mix you nutrient solution to the proper EC and pH, water your plants and call it a day. That's all you need to do.

What is the proper EC in coco?

Since this thread is popping back up, let me conclude that I ended up never using my ec meter again. I don’t check runoff, this isn’t dwc, it is irrelevant. The mfg feed charts you should be using just list the EC as a general sign of strength.

It is very easy, yes I was complicating things but it was because I was new and should of started with 1 plant and grow from there. Bare essentials ended up being all was needed.

I fell for the whole perpetuating makes more weed nonsense. I fell for it all and 1200$ wasted later I can see why a lot of nonsense is out there, I am not the only one.

I solved this problem with switching to tap (possibly) and watering thoroughly/frequently. runoff could only try to spell that out for someone but really, what else can it tell you without top notch equipment telling you what is in it and even then, it probably will spell out the same thing.

Edit I also removed calmg and never needed to use it again either.

I am under impression that we been known what the plant needs and how it uptakes it etc so I now share that for anyone I see who is asking runoff questions. For coco, these threads are meme value. Avoid being roasted for it.

There is no exact proper number. I never go over 1.5 anytime during the grow. I am of the opinion that the feed charts many go by that have you feeding 2.5 and higher are the cause of many issues some have. Cannabis never needs ec that high and feeding at such high levels does not increase production it just costs more in nutrients and often causes problems. Overfeeding is one of the main causes of plant issues.

Total ec 1.5 or 1.5 of solution? Asking for tap water folks. Im assuming you meant just solution. I personally do big pots 3-5 gal and light feed with total EC of 1.9 or shy over 2.0. I just switched to maxi.

Total. I count the ec of my tapwater as part of it. I use MaxiBloom but less than what they call for. Plants stay nice and healthy without issues.

I assumed I had a few rough leaves from a slight miscalculating ph meter, vpd off or scrogging real dense canopies in small space but aside from that, no issues.

Switched to maxi from flora in mid flower too if anyone ever wondered if you can do that in a rare scenario. Plant continued fine.

They only recently got signs of burn but I was already scaling back the EC to 1.7 and maybe next time 1.5 as @xtsho might of just inspired me to step outside the chart a bit.

I did not want to mess with anything unless I knew for sure that it was ok. Was doing great following the manufacture. Edit it is also because I did mid flower feed one week into late flower by mistake.

I suggest ignoring manufacture's charts. 1.7 is hot, I think 1.3 is the highest I've used. (Jacks 321) What's the EC of your water?

I use 1.1-1.3 EC max(per using PPM 500-650 max) this is including tap water which is 40ppm approx .1 ec

Same nutes, GH? And that is some fiji water you are getting haha is that city, well or other?

I see a lot of people feed that with GH (1.0 Ec total) but I just trusted the mfg and got excellent growth up until first week late flower and have yet to trial error if my hickup caused some nute burn (feeding mid flower feed still.)

I see people get tip burn a lot like it is hard to avoid but shouldn’t be extreme. Again, scrogging densly or growing small pots/aggressive feed I suspect can show some spots and burns.

.5 Ec which I find to be pretty average in cities in the us. Like .3 - .7 EC was the average I came across with my limited but many observasions online. I know water will vary greatly but I am talking water that you can expect to drink and not taste to faul to drink. If so, I would try it out, worked amazing for me.

I measure mine when it seems like it’s growing slow and probably has buildup. Comes out like 2.3 and just have to flush back down to 1.5 (jacks) or whatever and raise water frequency

I pretty much flush feed my 3-5 gal pots each feed, until the pot is gushing. I get excellent growth, there should be a competition for just vegging autos and photos, I would enter in lol.

I have yet to meet key mile stones in the other half of growing but I became addicted with the fact that coco just grows so damn good. Just pick a good nute line and let genetics and the nute line shine through you!

I would open up a discussion and make brand changes and etc if the basics do not resolve a clear critical issue.
