Osmocote Plus Plant Food: Discuss Its Use With Cannabis Here!

I have been using OC+ and a few nice additives here and there for the past 5 grows and turning out some real good bud.

Next grow will be some straight organic to see what happens, and compare overall results of weather it is worth the effort for me to use anything but the proven OC++ regime that has been so successful so far.

I don't want to stop using OC+ completely, so I will use it on every other plant for now and always be confident I will have at least one hassle free healthy plant to count on.

I do have a WW clone in one pot now that has no OC+ in it, but DynagroBloom as the main nute. It is less lush green than the OC+ clone right next to it using the same soil. It is still healthy, but I think she might end up a lot paler. And if I stop the DGB completely and use just the Molasses and Snowstorm Ultra, It might get to the point of turning out with a goldish hue of which there is a hint of now.
Did this to see the dif since I had the same strain to compare OC+ to a liquid nute.

So far fast dry test buds from both plants are so good I might only get to see if there is any difference in taste.

This is 4th generation clone of White Widow that I think is the best weed I have smoked this century.

Well these test buds are even better. 2 hits last a very long long time and keeps a high level of buzz. I had actually written the original WW off for dead when it was a seedling, but all of a sudden she took off.

And I have been working on this one post for the last 2 hours. Bed time. Ciao.

#1) I'd have no qualms using Ca-Mg throughout the grow, but then again, I use coco, which has an affinity for that, so my dosage is higher than usual.

#2) Not me. DocBud would say for nice meds, OC+ in perlite hempies, with SSU when flowering starts, until the finish. No flush required.

#3) Dunno, my hempy stuff was a disaster.

Yay! Another Michigan grower! :circle-of-love:

And another MI grower here. Just wanted to add that here in the metro detroit area, I don't see any real need to supplement with Ca, but I saw possible (minor) Mg deficiencies. 12x 1 gal grow bags filled with 2/3 coco + 1/3 perlite. 2TB OC+ per unit, all grown under 400W CMH (Philips Retro). Big D city water pH'd to 6-ish, with small amounts of occasional supplements- a tea from a local hydro supplier, and some old blue mountain organics foliar happiness (or some such nonsense). Nothing special or expensive- looking to just supply meself for a while.

I grew various strains- White Siberian (WWxAK47), Claustrum, White Widow and Suuuuuper lemon haze. The harvest is progressing, but like some others, I find the yield of WW kinda sucked (less than an 8th). Not lots from SLH, either. The variation between genetically related plants was really disappointing- one of the White Siberians is still maturing well past when the sativa hybrid (Claustrum) was ready. But that one will have by far the best yield.... eventually. The 2 claustrums look like radically different parentages- one was dark matte green with typical thin sativa leaves and big fluffy buds, the other has wider, glossy leaves and kinds flat-top buds. I'm likely guilty of early harvesting- just a few amber trichs are enough for me to break out the clippers. Bottom line- maybe 3oz in a 2ftx4ft area. Not great but will keep my eyes red for months.

Keep growing and voting here in MI!

Chow!
 
hash, if u use dynagro's protect u'll prolly never need to adjust ph. that's been my experiance. i use d-gro on my entire hydro grow & rarely do i have a problem. of course i just finished a seed run in soil w/oc+ & a VERY simplified tea (2x) w/no probs at all.
 
paw I only have one of those cheap triple meters, not sure how accurate it is.

And sometimes it gives different readings in the same pot. One pot was like a high 5 throughout and the plant showed no signs of trouble. As a matter of fact it is some kick ass Dinafem Diesel. (freebie)

Majority of the time the meter is right around mid to high 6's.

It is difficult to try experimenting with other nutes and methods with the great success that OC+ gives. It doesn't get much simpler than OC+.
 
that's frustrating, isn't it? i'm assuming u've calibrated it. good one's are expensive as hell!......& u still have to calibrate. different scales & all, that's why i gave up on ppm/tds & just use total ec & ph. i hear ya 'bout the oc+....it feels like u're cheatin'...
 
no calibration. It is one of those cheapie dual probes with moisture/light/ph.

Doc says you shouldn't have to worry about ph in soil that much, and I don't.

I have had very very healthy plants so far. The potency and quality in general keep getting better as I learn.

What I have is as good as if not better than anything anyone else shows me they have, and they agree :cheesygrinsmiley:
 
i don't doubt it at all. so long as u're water has a total alkalinity of less than 100 & u'rs must be w/in the proper range. my well water is so high in minerals that i have to use 2 filters or i'd be getting cal lockout. no chlorine issues, of course. i just completed a seed run, in soil, & couldn't believe the harvest. of course i've got a bazillion seeds, now!
 
Here is a water report from the local company.
you need to click on it to enlarge it.
I don't know what you mean by the u'rs, but the alkalinity is 52

Checked my girls again and they recieved their second dose of alfalfa/molasses tea wednesday. They look great, already have some pretty nice buds and though I don't know if the tea helped it sure didn't hurt. 4 weeks to go, going to hit them with the tea one more time and start the SSU after that. I am getting low temps in the mid 40's and highs in the mid 70's but things seem to be just fine. I don't PH either with soil but my water is very good just a little high in PH at 7.1 or so but no PH related problems at all.
 
Howdy. :)

I was wondering if you all could help me with a recurring problem I have. I hope it is okay to post here, as I would rather post here because I use OC+.

First, a little about my growing methods.

I germ using rockwool cubes, and transplant into 18oz solo cup hempys (the type with the square bottom), using 1tsp of OC+ distributed into the medium above the hole and below the cube. I use 100% Perlite.

I checked my TA about a year and a half ago, and Doc said it was just about perfect, so I water using tap which has been set overnight, and PH down to around 5.8 - 6.1ish.

I currently have 5 ladies, and one is starting to show the problem I often see.

Here is a picture of the problem.

It usually starts like this and progressively gets worse, mostly affecting the middle and lower part of the plant. The leaves will eventually turn all yellow/brown and seem to die.

The other 4 plants are not showing any signs at all, and all get watered with the same water.

Any ideas? I have tried numerous things in past grows, such as foliar feeding, using Earthjuice Microblast, Epsom Salt, etc. I have tried using the various troubleshooting posts to determine the problem, but I can't seem to peg what it is.

I really would appreciate any help solving this, as it is plaguing me through numerous grows. :Namaste:
 
I think that looks like a calcium deficiency:

I'd probably hit them up with a 5ml/gallon dosing of cal-mg. Someone else may chime in, I'm no expert!

Yeah, after checking the Earthjuice, it has magnesium but not calcium.

Sounds like it's meant to be used with tap water instead of "clean" RO/Di.

I missed this when you first posted it HermitCrab...

I agree it's a calcium deficiency. For some reason it's pretty common with mj and OC+. I had to deal with it on every grow as well. I top-dressed with a little more OC+ and started using Cal-Mag with every watering and it went away. The TA for my tap water is in the correct range too, I guess our plants are just gluttons when it comes to Calcium and Magnesium.

:Namaste:

The Cal-Mag definitely helped. I may start using it regularly then as well. Thanks for the tip!
