flushing my coco/perlite mix - do I need to add calmag to flush??

hey guys, I've got a lady that's been flowering for about 45 days. Shes sitting in a 3 gal pot with a 75%coco coir 25% perlite soilless mix. I also added some dolomite lime to the mixture for ph control, but I've got what seems to be a ph problem (brown spots, every pic that looks similar says deficiency and flushing will fix) and I was wondering about flushing with coco. Do I need to add Cal-Mag to the flush? Wouldn't a heavy flush with water only drain ALL the nutrients out of the mix and start starving the plant?

pics would be nice but my guess is you should have been using cal-mag if growing in coco coir

I don't think flushing will help as it's lacking...not over

I've been using cal mag the whole time. never watered without it. fully amended the coco with it before planting, etc. What I'm wondering about is flushing. Do I still need to use cal mag when I flush? That's what I'm asking.

don't flush coco with plain water.
if you feel you must flush it, do use calmag and a weaker solution of nutes...at least 300ppm ( .6 ec ) total

cool thx man. I guess I'll throw in the calmag with some micronutes just to keep it feeding on something until the next watering. I figured flushing with water would be a disaster.

make sure to ph also

Hey dude, coco is supposed to be neutral, theres no need to add dolomite. Since your growing in coco, calmag is a must. I never flush with plain water. I always add some calmag and blackstarp molasses, unsulfured of course.

ok so the majority conclusion is to add calmag, and even light nutes to the flush, but what about my final flushes before harvest. My last grow was soil so this is new ground for me. All I know is calmag smells like an old fart and I def don't want my nugs tasting like that. And its funny that all the fert we use is all earthworm and bat shit and urea(does anyone use urea-dominant nutes for Nitrogen? that stuff plummets my PH into the depths of hell.) and all other waste products. So is it ok to do just plain water for the last two weeks while I flush. I would imagine the lower leaves would yellow and fall off first and that two weeks wouldn't be enough time to starve the plant to death, but how does final flushing go with coco?

just feed them water

Final flush is the only time you give plain water. The goal of the fianl flush is the plant uses whats left of nutrients in the medium and cleans herself of any leftover nutes so you get a noce tasting bud. Lol dont worry your buds wont taste like old fart hahaha. But for great tasting buds, you need to give them carbs in their flower cycle.

I use and swear by coco, the biggest difference from soil is the coco is neutral and requires calmag. With coco, it gives you even more control on what you will put in the medium for your plants and soil perculation (how porous the soil is) is much higher than peet.

I dont know of any urea dominant nutes except my own pee lol

Thanks man that's what I figured. Yeah I had this Shultz transplanting solution stuff that said to add a capful per gallon or some shit and it took SOOOO much ph up to get it to 6.0 so I threw that stuff away. Here's a few pics of a couple of my tops taken this morning. those other pics were from the bottom and the flowers down there aren't anything to see. Neither is this to most of you out there but I'm happy as can be except for my ph/calcium deficiency thing.

If your looking for a supplement for transplant i would suggest a b1 supplement. Depending where your located and what products you have access to. I use supermax b1 and its a breeze.

Also may i ask what schedule your using? Seems like your flowers are fluffy and could use a bud enhancer (depending which week your at). Did you buy a cal mag supplement?

Anyways im here to help if you need to.

Thanks for the help man! I'm using the foxfarm nutrient trio. Im adding 3ml of micronutes 1 ml of vegging, and 1 ml of tiger bloom (week 5). week 6 takes out the vegging compountd for a cycle and boosts the blooming compound up a tsp.Yeah I've been using cal mag since day 1 - every watering. I also flushed the coco with 3 gallons of cal-mag'd water before doing anything with it. And I added that dolomite lime, not necesarrilly for ph alone, but also because it has calcium/magnesium in it(so I'm lead to believe) and I figured that would be a good thing to amend the coco with anyay, but speaking of B1 supplements I just got to little bottles of superthrive. I've always heard mixed reviews but I figured I'd give it a shot myself. But yeah that Schultz stuff was a 'transplant solution w/ b1" but I'm not transplanting anything right this sec but I'm going to see what that superthrive is like.

Superthrive is great but dont go beyond a drop a gallon or you have problems.

Also a bud enhancer would be great. The only bud boost i recommend is big bud. It has amino acids that no one else has. Also a bud hardner is great for weeks 5 to 7 or 8 for 10+ weeks.

Finally a ph and ppm meter is a must. Since your working with coco its important to know how much concentration your soup has... Let me know if theres anything else.

Ps. What are you growing?
