I don't know what's in your nutrients so I'm not going to say to stop using the calmag. I use tap water and calcium nitrate as my primary nitrogen source which provides plenty of calcium. The micronutrient blend I use has adequate amounts of magnesium as well. But any decent hydro nutrient should supply both.

I see you're using a P/K boost. Too much potassium can lockout nitrogen, calcium, and magnesium. That's why I'm not a fan of additives because if used in excess they can cause issues. I run just base nutrients that supply everything the plant needs and have healthy plants from seed to harvest with none of the issues many growers have. Those issues usually show up mid to late flower and typically there isn't much that can be done at that point as the symptoms tend to get worse regardless of what's done.

I wasn't sure about the pk boost, but used it since I already had it. At the lowest recommended dose.
Bought so much different stuff at start just to be sure i could handle any deficiencys on the spot without the need to wait for mail.

If I could do it all over again I would choose the simple but effective route without the additives.

Many deficiencies are caused by nutrient antagonism from using too much of one thing or another. A balanced nutrient is all you really need. I look at all those bottles of cannabis specific nutrients and just shake my head. I put the cannabis specific nutrient industry in the same category as LED manufacturers marketing their 100 watt at the wall lights as equal to a 1000 watt HID.

Jacks 321 will grow spectacular cannabis plants for a fraction of the cost with just 3 parts. When you finish up all the bottles you have take a look at that.

The plant is eating the leaves. This is not deficiency. Leaves also die off in late flower
What do you have 3 more weeks?
Lots of tip burn though you could be locked out and that is why they are being eaten so fast.
Maybe just water from here on out.

Is that purplish colour on tips over fert? Or referring to my other symptoms?

imo that is kind of normal for this stage of growth I do think it is some sort of deficiency more than likely as you see that all the time in different stages of growth, or the leaves are showing their fall colors, either way I would do nothing about any leaf issue at this point...maybe pic off all the dead yellow ones so light can get on anything good and increase airflow around the buds.

Ok ill take off the ones that are very yellow tomorrow when feeding.

Should I dial down nutes(75% recommended dose)? To make sure I'm not overdoing my nutes at harvest.

How To Set EC Targets - General EC Ranges for Cannabis in Coco - Coco For Cannabis - Plant Science

How strong should your nutrient solution be for cannabis? The strength should be determined by EC or PPM. We walk you through how to set EC/PPM targets.

Very useful info on that site. Went through most of it including the link when I changed to coco. I'll read again though, refreshing forgotten things.

I should learn how to calculate ppm so I can be 100% sure that my ratios are right. Just one of the things that got postponed hah..

Really? Can you post some pictures of Cannabis plants grown with Jacks 321 in the veg stage, without supplements, that don't have deficiencies, please. Can't find 1 picture on the internet that aren't lime green plants. ALL have deficiencies. Even the Youtubers who recommend Jacks have deficiencies, while they are explaining that Jacks 321 is a complete nutrient and it's all you need, look at their plants, they are all light with what looks like mag deficiencies.

I've been using Jacks 321 for 3 months and have tried everything up from down, backwards and forwards. I have these 7 strains that I have successfully grown without deficiencies using CES nutrients and now with Jacks, I can't get out of veg because of it. Starting to think it's BS and these YouTuber's have just found a company that will pay them for talking about their nutrient line. I've even contacted Jacks about it and not been helped. I've caught dozens of people throughout the internet saying things like, Jacks is complete/perfect, it's all you need, followed by things like...
"If you need more mag just add 1 teaspon or 1 gram of epson salt" ?!?! LOL.
When I think about it, I'm reading advice from mostly narcissistic stoners, sorry, not sorry.

Are their any legal professionals who grow for a career/living in a professional atmosphere that stand behind Jacks 321?

If so, Please post pictures of plants in veg.

Appreciate the help!

There are growers on this site using it without any issues. I don't use Jacks but a product very similar along with calcium nitrate.

The VitaGrow I use.



Grown in coco with just the 3-10-20 and calcium nitrate.

Your plants look great and look just like my strains used to look with CES Nutrients.

I notice you aren't using just Jacks 321 though. You are using supplements too.

Which gets me back to my point, Jacks 321 is not complete as all the youtube videos say.

I bought Jacks 321 to learn how each micro/macro works and be able to adjust them, so if it's just the MPK I need to buy and play around so be it.

I did go out and purchase CaliMagic and tried adding this at 1.2ml per gallon and then 2.5ml per gallon. No change.

I tried switching from my R/O water (20ppm) to store bought distilled water and no change.

And this last couple weeks I have been using 3/4 distilled water and 1/4 (24 hour sitting out) of my home tap water, which comes out to 115ppm as my base water before nutrients.

My environment is spot on, I have good gear. Cloudine t8 with temp/humidity controller, fans for air flow, I'm in a tent with my own leds (samsung 301b) - my numbers are 500-600 depending on how tall each plant is.. I use apogee sq520 for readings.

Would you mind recommending which MPK I should buy?

And also, what is your ppm towards end of veg?

Thank you!

Very pretty, thanks so much for the response, with the pictures.

Do you use these two nutrients the entire life, all the way through flower?

Thank you!
