Is this from using too much CalMag or not enough?

[zeroday]

There are 3 plants in this batch. I'm growing in Soil. Last three feeds, the plants have had 1.5ml calmag, 7.5ml calmag and 5ml calmag (per gallon of water). I was thinking I gave it too much. The discoloration started roughly 3 days after the 7.5ml per gallon water. I only noticed after I had already fed it again with calmag at 5ml/gallon.

Thanks!

Hey welcome!! The stuff I use says 2 ml per gallon of water

 

[Backlipslide]

Sorry I meant per litre

your problem looks to be pH related to me... and not a magnesium deficiency, and it is too early to be a calcium deficiency and it also does not look like this. What pH are you adjusting to?

 

[zeroday]

6.5ph in soil. I'll check the runoff. I have not done so since they went into flower.

pH of water with nutes added, not runnoff or soil pH my friend

I love the accuracy. If this is indeed the pH of the final solution after mixing nutes and right before you applied it to the plants, then I suspect that your nutrients are very light on potassium and that you should use your ability to be accurate to adjust to the sweet spot where the most elements are the most mobile, at 6.3 pH. Remember that soil drifts upward, so by adjusting to 6.5 and above, you are missing out on any of the elements that are mobile at the 6.2-6.5 range.

Have you started giving bloom nutes now that bloom has started? Your soil did a fine job supplying the nitrogen that was the macronutrient up until now, but now you need something more than what is being supplied.

I just looked back at the notes from when it was in Veg.... So embarrassing..... I was feeding them the same PH as my coco. I had 2 soil grows and a coco grow going at the same time. I accidentally fed these the same PH water that I was feeding the coco.

I'm thinking I should flush. They budded, and then stopped growing for the most part.

Here are all of the columns in the spreadsheet.

Jeeze, I put my spectacles on. I am noticing some of the leaves are starting to look like I have nute burn going on. I'll go get a pic.

 

[Emilya Green]

dont worry about flushing... keep the nutes in there. Just correctly pH the next time so you set the container to the correct range.

First pic is a plant I call SF-TG-032419-2. Rolls right of the tongue, doesn't it? This is growth towards the top. Other bud sites look similar, brown tips. The other thing I noticed, is I did two bloom feeds in a row. Nute burn and PH issues?

The second pic is of a bud site on SF-TG-032419-3. It is an example of what the bud sites on the other two plants looks like, which don't seem to have the same browned tips. Of note, the plant with the burned tips and the most discolored leaves is the one that I did LST on. The other two that are the same strain and fed the same way, no browned tips, they don't seem to have nearly as many discolored leaves down below. Wondering if this is because the LST put some amount of stress on that one plant, and it couldn't deal as well as the other two? Who the hell knows? Just wondering.

SF-TG-032419-2 Nute burn?

Also, if my images are not good enough, let me know, and I'll get my wife to take them with her gear.

 

[Emilya Green]

I see nearly perfect plants there. If you don't at least burn the tips just a wee bit, you aren't trying hard enough. I would be very proud of this grow so far.

 

[zeroday]

Ha! Thank you so much for your support @Emilya !!!

My meds will be out just around when these finish (my auto batch finishes at the same time). I can't afford the dispensaries. True story.

Your words have helped ease my panic/anxiety. That and a puff of Peyote Cookies (at home smokin legal).

You are very welcome, and welcome to the forum by the way! You have happened on the very best cannabis forum in the world! I have run a couple of them myself and been the member of several... it is this one that I call my home. I hope you stay with us and I see that you have already put up a couple of journals AND put them in your signature! This is going to be fun!

 

[zeroday]

Wasn't sure if you suggest 6.30, 6.31, 6.32..... lol, j/k.

that advanced cali magic also has kelp in it … I have used advanced twice and burnt my plants twice ...just fyi ..its heavily concentrated I would suggest using half of what they say . I can offer no other input as im not a soil guy .
