Spots on a few leaves Sweet tooth in coco

I respect your experience my friend, but we all have different viewpoints and ideas about what a healthy plant is and how to grow it. Don't get me wrong! This isn't the first time I'm hearing about your recommendation on feeding in coco. People have lots of methods (sometimes opposing) when it comes to growing in soilless mixtures. One time a guy called me a moron for not feeding my plants 3 times a day in coco! But they don't know what happens when they put that much nutrients in their pots. They think every time they feed their plants, they are doing magic and nutes immediately transform into happy green leaves! Every time we feed our plants, they store lots of unnecessary and even harmful nutrients in their tissues (roots, stems, leaves, ...), because they are always uptaking what is found in medium without calculating their needs, to the point that they finally get burned! If you feed your plants the right amount/ratio of nutes at the right time, you don't really need to feed every time you water and it's best that you give them plain water once a while and give them some time to rest and use what is already stored in tissues. Feeding mistakes is one of the most important reasons that even the most experienced growers whisper these words to themselves after they first smoke their harvest: "Maaan! That shit was supposed to be a bomb! What is this crap?!". Of course they always blame breeders and talk shit about them! :wink:
I'm curious now. Have you ever alternated feeding with plain water or just fed plain water for extended periods in plain coco yourself? Like actually grown plants in plain coco and done what you are recommending? I'm wondering because I have had issues with what appeared to be nutrient lockout on the occasions when I have alternated feeding with watering or tried water alone repeatedly in straight coco. I want to know how to grow better pot than I do currently, anybody who doesn't is ignorant and doesn't realize that they have stopped learning. So I'm not asking this to be an asshole, I'm asking because I legitimately want your point of view on this.

I think what you're getting at is that you should feed at a level that is just enough for the plant to utilize while not overdoing it because that is not just not helpful, it is actually harmful. I agree with that, so much so that I take it a step further and posit that feeding at the appropriate level at a sustained pace is more helpful in this particular medium when compared to alternating feedings. I say this based only on my own experience, not the "conventional wisdom" I end up quoting so often when talking with you it seems. ;)

It's worth noting that I think you're really on to something with the following:

...if we're talking about soil. This is coco and it's a different ballgame entirely because of the nature of the medium.


.........in my experience

No!! I'm just clowning around and wasting my time and yours with a load of crap which I've never tested myself!! :wall:

My first cannabis grow was in coco, because I had experiences with growing other plants (especially cacti and succulents) in coco and I felt confident that I could pull off my first try straight in a soilless medium. That was in coco/perlite (60/40) with my own handmade nutrient mix (a 20-20-20 and a separate calcium nitrate supplement throughout the entire grow) under 400w MH for veg and 400w HPS for bloom. I started feeding my seedlings (Master Kush, Sensi Star and an unknown landrace indica, which all turned out to be heavy feeders) after 10 days, vegged for approx. 2 months and stopped feeding them all together at the end of 5th week of flowering. That was actually a triple feeding cycle: feeding 1 was 20-20-20 (never more than 1.2 EC at pH 5.8 ), feeding 2 was just cal supplement (at pH 6) and feeding 3 was plain water (again at pH 5.8 ). They were some of the most delicious and healthiest mj plants I've ever grown. And of course I'm still running in coco most of the times.
just fed plain water for extended periods in plain coco yourself?
I don't really remember saying that "you should feed plain water for extended periods in coco", because like I said a few days ago:
You need to feed your plant regularly when growing in coco. Coco is a completely inert medium. It just releases some potassium while absorbing the available calcium in your nutrients.
You told me that "you SHOULD feed with every watering" and I'm telling you that it's not correct. And let me tell you that I don't believe in predefined and strict feeding schedules at all and don't have one. I don't even take a look at recommended dosages or instructions and made-up rules given by companies or growers.

Nutrient lockout from feeding plain water?! It's like you're speaking chinese to me right now! :confused: Please fill us in with more details.

If there is an infection/infestation, it appears as if your current method is keeping it at bay well. It helps to explore every avenue of treatment, so long as it doesn't deviate from what is working so well for you already. Small spots that are as scattered as yours appear to be caused by minor pests. Some also match the appearance of RUST. Pruning can vacate your growing area of vectors of rust contamination. Cleaning your leaves with fight off the pests. Let me know how it goes! :)

Not to try to stir the pot, but I have heard both so many times, some say flush coco others say never flush fully but go with lighter doses..... So on my last trip to the hydro store I simply asked the canna rep that was in-store, according to him you shouldn't flush unless it's a dire need,aka way over ferted,or if you allowed the coco to run compleatly dry(also told me not to let it dry compleately but to maintain a moisture level not unlike cloning) but that if you do need to flush, to use 1/4 strength nutes in the last gallon because its a completely neutral medium that requires additives
