Id be tempted to think you need to up the ante a little bit.....

Your leaf tips are pristine so I dont think that would hurt.....


Generally there is a high enough level of magnesium to support the plant without epsons....

If your using it as directed, you shouldn't have to be adding anything to it, try to keep your grow simple as you can. Your are using RO water don't add anything, Jacks will do its part, your part is not to screw something simple up. Over watering and over feeding are really easy to do, use Hempy pots for simplicity and excellent results. Go to D9's 5 year grow using Jacks, his grows are/were huge, he added nothing.

@guest4200: more information would be good. How long using Jack's? Medium? ec of nutrient solution? etc

Been trying out the jacks for 2 months now using 1 gallon root pruner pots feeding 1 part jacks to 0.67 parts calcium nitrate. pH comes out to 6.0-6.1 @ 750 ppms 0.5 meter.

My mix is 50/50 bonaticare coir/perlite hand watering for now but will be using drippers soon on these.

how high should i go with the ppms?

I use the same stuff more or less.....

As I said in my first post......your leaf tips are pristine .....

I go largely by what the leaf tips are telling me....

When I see some minor burning of the leaf tips....back off just a bit....


raise it 50 ppm or so....and listen to what the plants are telling you....



That being said...... I was expecting to hear you were feeding at 500 ppm or so......


750 should be sufficient........ but the leaf tips say they could use a little more....


Your plants look good by the way........


I was looking at your picture...... I presume the plant you are concerned with is the lighter green one?????


I also assume that those are seed plants?????


Keep in mind...that when you run various plants....they will have slightly different needs......


I ran 2 clones for awhile.... one looked great....the other would get mag def.....

Now that I run the hungry plant at a higher ppm...it looks perfect.....

no not seeds there all cuttings from the same mother. they don't look as good as the ones feed GH. But im trying to get away from them now that the company sold out.
Would be nice to save a ton of money if i can get the jacks to work right.

Jack's works if you follow the directions, deviate and you'll have problems. Marijuana is a weed and will grow like one if you give it what it needs. Remember KISS, keep it simple stupid and you will do very well. Jacks is .17 cents a gallon and GM is $15 on sale. Burning Ropes cloner is good one, surprisingly simple and effective and best of all cheap. https://www.icmag.com/ic/showthread.php?t=42847 Your plants look great, your problem is that you don't know what a fucked up plant looks like. Look up sick plants and you'll see what I mean, wait until you get powdery mildew or spider mites and then you'll know how good your plants are looking.

Anyone experiment using just the 5-12-26 in flower with no calnit? A tsp per gallon maybe?


I cut back on the cal nit after stretch and cut it out completely at the end of week 4. It helps the budding accelerate faster and improves the calyx-leaf ratio.

Interesting, when I cut it by 50% I incurred an immediate calcium deficiency with severe rust spotting on all fan leaves.

Third coast..... go Blue....used to live in aa...

anyway.....

Its been my understanding that a calcium def shows itself as you say rust spotting....


If you can ....can you tell me if there is a dark ring around the rust spot???/

WHich may distinguish that spot....from other spots....

Mid to late flower, the plant is barely using calcium anymore and tissue analysis confirms this: http://www.mrnice.nl/forum/15-plant-doctor/5456-tissue-analysis-charts.html

Notice calcium knees off at week 4; this is why I reduce it here. Cutting it out completely is to help the plant use up available nitrogen. This allows a shorter flush and I find lower nitrogen levels in mid-late flower produces fatter buds

Interesting link. Your right that the calcium knees off at week 4 on the indica sample. But on the 20% sativa the calcium need goes up after week 4. By week seven its at almost peak levels. I think the specific plant your growing is going to have its own line graph.

Ive become super interested in this, as latley ive finally come to the conclusion that all salt ferts are really about the same. Im interested in switching over for simplicities sake.Just a question for anyone who switched from a multipart coco line. Is resin/yieled about the same? Also does anyone add any natural elements like teas, or foliars like sea green, pure protein, humic, etc. I think these things help a lot to balance plant health, just wodering if any interactions could be caused by these.

yeah theres a much more active thread on this line at the farm. i have found jacks to be a really good kiss style formula in the sense that both veg and bloom plants seem to respond well to it. maxibloom and maxi grow work great too. easy as shit and you can mix em for different profiles. plants on the 321 style seem happy in my set up.

Im on board finally. Was running gh 6/9 for a lot of years. The recent ownership change was just the little extra motivation I needed. Im curious to do the math and see how much cheaper running this stuff is. Although money savings was only a small part of the decision to switch. I liked the idea of not buying the big plastic totes of gh and taking them to the dump. Plus there heavy as well to haul around. And somewhat a pita to fill out of the little spigot valve unless u have them elevated.

I plan on treating the nute like normal for coir. I am a believer that most branded nutes are pretty similar in quality and effectiveness. As long as the npk matches up. U might be able to squeeze a bit more or more resin with different additives, but the guys I learned off of were hitting 1.5 to 2gpw, with just base nutrients. Didn't matter what brand either. just 1 to 1.2ec thru the whole plant life. if u do this with some run off measuring run off ec to make sure ur not getting build up, the flush is really negated, as u never put too much in there to flush out anyway.

Would take any tips on using this stuff with coir though. im always willing to learn new things. My friends already told me how to make a stock gallon solution of each so I can just add 10ml of each to the res per gallon.
