Deficiency: Ca? K? Please take a look!

easier to flush and start anew then to try and micro adjust your nutrient mix... fwiw

feed a complete plant food, no additives.

I guess first I need to say that I have read quite a bit about Pro-Mix, especially on this site. I hadn't seen that .pdf you posted with the precise nutrient content of the Pro-Mix BX, but I was aware that it does have a nutrient pack included.... there are plenty of organic growers who use it... it is in fact included in BurnOne's "Organics for Beginners" thread here. You'll notice that he recommends adding 2TB of Dolomite per gallon to his mixes as well, which is why I had done so... he is, after all, the moderator of the organics forum.

As far as pH, everyone I have discussed it with on this site (especially in the Earth Juice forum, which I actively participate in) says that 6.0 to 6.3 is a good target for soil-less, with 6.3 being right on. In fact, the "hardcore" organic growers say that pH doesn't matter at all in organic gardening. All that being said, I am willing to try just about anything at this point.



I think the pH recommendations of 5.2 to 5.8 are for hydro, which is of course lower than those recommended for either soil-less or soil. I could be wrong. The most interesting thing I saw on that link you gave was that the grow and bloom contain Ca, which is not listed on the label, for some reason. Very good to know.

I dont know why i bother!(no-offence)
Deleted Response! Then you shouldnt need any assistance! Nice healthy plants! Nuff Said!

I had that exact same problem with my plants. I use promix BX with 1/3 worm castings. They did that leaf edge browning in veg, but on a few leaves on the mom. Well, her clones did it too, and our SOG of sensi star is a bit of a bust now because of it. However, we did resolve the problem from getting worse. Its a calcium problem. Normally I add a tablespoon or so of dolomite lime to each pot even though it says there is some in the mix. Well I forgot it this time round (for whatever reason I had put it somewhere other than where I keep my plant stuff) and ended up totally buggering everything up from the get go. Will NEVER forget it again!!! and make sure the problem is resolved before flowering cause it will cause a crap yield ( we have almost no fan leaves left on our flowering clones 34 days in. boooo urns.

I'm not saying that I don't need any assistance- far from it. I'm just trying to narrow it down, and say that I'm not coming at this from the perspective of a complete novice... all I was saying is that other people have other points of view, and I don't know what's right and what's wrong- that's why I said "I'm willing to try anything at this point."

The info you provided is very helpful- the two links are bookmarked... calm down.

hmm. my bad. I just re-read your first post. you use dolomite too... maybe too much if its in the nutes too? Flushing with epsom salts probably the route I'd have taken in that case too- but that does seem like a lot of salts/gallon? less is more, easier to add more later than reverse effects of too much. I think I need to stop posting while stoned S

Wow, an EC of 3.0 and you haven't fed in 4 weeks? Especially considering that it's Earth Juice, that's really high.

Also, Pro-mix already has Lime added. Your runoff pH is obviously OK, but is there some reason you feel the need to add more? More is not always better.

I always add 1 cup of dolomite lime per CF to my pro-mix, along with other stuff. Works better. It needs it and you'll be happy you added it next time around. If you let your soil mix sit moist for several weeks to several months, it'll be better still.

Now thats interesting GM, a whole cup to each cubic foot? wow, this seems alot, how many TBSP's is that? it seems alot considering the Promix the OP is using already comes with 2 types of added lime, including dol-lime. Have you got more info on this GM, ive never used promix so im trying to get my head around it bro & i know you know the score on organics, soil/soiless etc.

Also what PH should the OP be runnig his solutions at?
The promix comes low/acidic iirc, are you adding all this lime to get the PH right up? where does the 1 cup pcf put the PH to? (does this just give more buffering) so many people do different things its confusing as hell!
Ill get there with the help of people like you GM! Cheers!

btw its the Promix BX with added Myco. & could you list your full mix please man!? N1

I use promix hp (has myco also, but I add my own mix of myco at transplant). I currently am using a hybrid of LC#2 as set forth on the "organics for Beginners" thread. Promix is one of the soils that are suggested for use in building LC#2.

If you do the math of 1 tablespoon/gal of soil, it comes out to 1 cup/cubic foot of soil +/-.

Remember, most of these companies add bits of lime (or whatever) so they can put it on the label, but rarely is it enough. I learned this the hard way.

Currently I am running
6 parts promix hp
3 parts good ewc
2.5 parts #3 perlite

per cubic foot of that finished mix I add
1 cup dolomite lime
1.25 cup good kelp meal.
.5 cup of Azomite

Soil then sits for 4 weeks in a bin. I wet with fresh ewc tea and turn weekly.

I fertilize with a decent organic liquid. For me, I've found that using the dry mix of bone, blood meal etc were not producing plants of the size/quality that I wanted.

Last run I used House & Garden "Bio 1 Soil Component" at a bit less then the recommended rate. This product has no calcium, which is ok for vegging since (as von pointed out, I am getting Ca with my EWC tea), but in flower, i use this Ca product 2 times at 10ml/gal of mix.
http://www.agroplasmausa.com/calcium880.htm
along with their fresh water carrier at 10 ml per 5 gal mix
http://www.agroplasmausa.com/universal.htm
If I want a bit more K mid flower I use some "sulfate of Potash", @ 2 tablespoons/5 gal of mix.
That's pretty much that.
The results were double of that of the dry mix of bone, blood etc. But it all starts with the soil mix. The promix has been much better for me then sunshine mix.

BTW - I know very little, but have been learning this organic thing for about 2 years now. What I do know is what works. This has worked big time for me. Easy, no deficiencies and double the production of the dry regimen or the guano mix.

Exellent man! Thanks alot for posting the very helpfull info & links.

Where do you source your EWC?, Too bloody expensive from the hydro shops at £5 for a little bag, Guano the same & come to think of it its all expensive from shops like that.

There is a EWC farm here locally. I use about 1/2 his product and 1/2 a bag product. fortunately, I get my EWC from the farm for free.

Look I'm a new member but an old grower. I seen all kinds of weird sorts and minor def's that we'll never understand. They continously do it in nature anyway and it has not done too much harm. I have a way of gauging these things: if most the plant is healthy and it continues to grow dont waste time, effort or money on cures for unexplained plant phenomena that dont really get in your way. You'll know when its bad cos it'll be bad, and they'll still come back!
