I gotta lose those waterfalls. HELP!

[myke]

What baffles me is the same strain is in coco right beside it. Does wonderful. Same food same room. It doesn’t show these signs/deficiency. So it’s something with the system.

Ok let's get back to basics here. If you water is 150ppm it's highly unlikely you need cal mag. You may need some mag depending on the nutrients you are using.

Can you list your nutes and parameters.. temps humidity and let's start working this out. I don't think there is one answer.

Also just because you have a deficiency does not mean you don't have enough available nutrients.

 

[Aqua Man]

Here's my guess. You didn't add cal mag to your nutrient mix Very VERY FIRST before anything else. Also, didn't add each part I dutifully with stirring in between each.
I bet it's lock out. Suuuuure looks that way

This is fucking rediculous. The sources in cal mag are highly soluble. Don't make me laugh even harder at you

 

[Aqua Man]

You blaming waterfalls when dozens of US have had success with it holds no weight.

Again reading and interpretation skills at thier finest.

And for the record here calcium is not very mobile and will show up in new growth. So it's likely old damage or possibly magnesium

 

[myke]

So are we just looking at old growth? The new growth seems better does it not? It appears that the sad looking leaves were from when you had issues that you corrected. They will continue to get worse but if the condition doesn't spread to other leaves I think you are good to go.

This recurring issue happens on mid growth leaves in the light and shade. It takes a while for it to show on new growth say 3-4 nodes of growth.

Ok list everything you are adding and have nutrient and additives... Your tap ppm 150 check..

Now can you give me all the parameters. Temps, humidity, etc everything you can

Ok ya I’ll take some pics.
Back in veg say week 2-3 I tried no calmag and 100 ppm epsom. 500 food. Still seamed to get it. Here’s a pic

Hard to tell once leaves get affected when changing things. In this thread I’ll start posting more about nute strength with pics so I can come back to it.

If I'm honest blind guess is ph. But let take this a step and a time. Stop trying to diagnose issues and start looking for the root cause. Aka get back to basics. Process of elimination.

Ok so nutes are pick one. Calmag is GH 1-0-0. Ph down GH. Temp day 74 temp night 66-68. RH stays a pretty consistent 40-50%. Additives are fulvic acid here and there. Lately haven’t used any. If I do I go 1 ml /l or less.
Lights are 9 - 48 watt strips.3000 About 24” away at the moment. Air is being pulled outside 400 cfm on low speed. Passive air pulling from my lung room which is cold 67. This is where my res’s are. Also have direct 5” hose from my furnace that sits on the floor in the grow room. So when ever my up stairs furnace turns on it’s heating the room 24/7.

Ph drops. What’s your guess. My pen says 6.1 -6.2

 

[Aqua Man]

Grab some tap water like 250ml and throw a tsp of baking soda in it... This is fuckin ghetto but ph should be about 7.8 I suggest getting a calibration solution.

How much oh drift are you getting in 24 hrs?

I’ve tried this before with my old pen. 7.9 is what I understand it should be. I have new 7 and 4 calibration fluid.
Ph drift is usually goes up. With low food I use a ton of ph down. Just doing a test now of 15 l of water. 30 ml a 30 ml b. 15 ml calmag. So far 5 ml ph down. Letting it sit a bit.

In a new res with you tap water add 1/2g per gal of actual water not container size epsom salt (magnesium sulfate). Then mix ratio of those nutes 50/50 gives a very nice ratio. After tap and mag sulfate add your nutes to bring it up to 700ppm of 50/50 mix. Then ph down to 5.8. check ph again in an hour and adjust back to 5.8 if needed.

Now in 24 hrs check that ph again and let me know what it's at. You want about a 0.2 increase.

Are you not running h202 or bacteria? This is something you will need to do.

The other parameters look ok for now.

Good good so we can trust the ph meter.

Now don't add any other addatives l without checking. Silica can cause precipitate if not added properly. So let's get a base plan and stick to it. Then adjust as ya need. It's not going to be a fast process so not insta fixes here. Need to give time to see how things improve.

Rodger that. My wife has been slow cooking some back ribs in who knows what kinda sauce but the smell is amazing.
Ya the Silica has been put away lol.
My coco plants are doing very well considering I don’t do much with them.No additives.

 

[Aqua Man]

Also can you take pics of the roots please. If you have root rot we need to address that and there is 100% gaurantee on that. It's going to make a lot of work for you to correct

Scratching my head on this. Didn’t see this post.
So .5 g per gallon that’s 3.7 litres for me. Of epsom. Then add food to 700. No calmag?
