CalMag deficiency? RDWC

[Driver733]

I find the flouride keeps the cavities away lol. I always have used city tap water just make sure to sit for 24 hrs and make sure its room temp first. Only thing i see is your temps and humidity is pretty low i find i get nutrient issues if i run to low with a low ph. ....

That looks exactly like the issue I was having, I believe it is a cal-mag deficiency, and what helped me is to raise the humidity in the tent. The low humidity causes the plant to use more water thru the roots than it otherwise would, which can cause deficiencies.

With a small evaporative humidifier ($40 at rite aid), I am keeping the humidity at 55% and the plants are thriving and growing vigorously. As soon as I let the humidity drop below 40%, I start to have issues again.

Good info

I haven’t checked yet, you’re the first person who’s suggested it may be bugs. Which damage are you referring to btw? And what kind of bugs should I be looking for? I’ll check for all species under a 30-60x micro right now, but it would be nice to know what to look for (I.e. thrips, mites, aphids, etc.)?

pic 4 where it shows your thumb. look about an inch to the right: see that weird looking spot?? i saw something in another pic that looked similar.

Science disagrees my guy

Ya but my jars disagree with science so ill take my bud over your science anyday it smokes alot better lol.

There has been a lot of very in depth experiments, done, and redone by other people to verify these things.
Your jars would have been just alittle more full, and just alittle more sticky.

Lol i dont even like smoking most of my stuff its too strong but your probably right it would but i guess id ask myself why would i, just doing in a lab vs doing in my garage/house i have diff variables im sure i live in the core maybe my co2 levels are high so gives me better growing conditions? cause i dont run one grow even close to the norms and make the best weed and most weed out of all my friends who grow, so must be doing something right/or wrong depends which way a guy looks at it.

Hey, whatever works man hahah not every one is born to be a perfectionist. The little difference just doesn't matter sometimes.
My issue is that without proper monitoring, and control, you can be okay for a long time, but its much more likely for things to go wrong and lose a crop.

Looks like bug or Foliar feed damage to me. "Calmag" issues caused by lack of said nutrients with a complete plant food doesn't exist in hydroponics, it's all pH related or root issue related.

Your first pic was a ph issue,probably gone now.Your tap water is fine stick with 3ml gallon calmag.The problems in rdwc start when u start dicking with things.Leave it alone!,ph can swing its what it does.
You dont need to let your tap water sit,its good water.better then your ro stuff.
You dont need to change the water anytime soon,you got your ph stabilize now leave it be.let your plants grow lol
good luck.

Oh and dont use rapid start or any other BS additives.Stick with the 3 part only.

Hey everything looks good otherwise!
I'm assuming you ment 550 PPM? if so, that looks good.
Make sure you are mixing your nutrients very well in between different parts. If they are too concentrated when you mix it might become locked out. It also matters the order you add the nutrients.
I would reccomend raising your PH. Vegetative stage, more cal/mag is consumed, and less phosphorus, so your plant will thrive better closer to 6.1 or even 6.3 (this is the optimal ph for cal/mag uptake)
I would also reccomend a light foliar feed of Epson salts for immediate relief to the plants

no I actually meant 550 EC, I’ve been gradually topping off raising the EC as needed. And the EC has been stable at 550ec/275ppm. I’ve been told mixed things about feeding. What strength should I be feeding them at?

I just used the rapid start when getting my seeds straws in the rock/wool and then when I moved to the system. I just use the floralicious + now along with the 3 part (and of course hydro guard, water temps get as high as 71-72 on rare occasions)

Your good then. Your EC ppm. Your messing us up what’s the deal? 1 EC =500 ppm. Get that straight.
Also if your gonna use that ro and rain water then up calmag to 5-6 ml a gallon. 3 ml if your using tap.
Again get up to date with your EC. What your saying is wrong. Take a pic of your pen in solution so we can read it.

Stop using floralicious +. Avoid soil/dirt products in hydroponics. It's fine for coir and flood tables. Not so much in DWC or Aeroponics.

Yeah good catch. Only use the 3 part and calmag. Hydrogaurd nothing else.

Nah man I think you should re-read my post. It said “feed strength: 550 EC.”
Then someone asked, “i assume you mean 550ppm”
And I said “no I meant to say 550EC/275ppm.”
I just forgot to put the decimal as “.550 EC”
I am fully aware of what the EC to ppm conversions are.

plants are about 3 weeks old. I just topped at the 5th node a couple days ago. What strength should I be feeding them in ppms? I’m very new to hydro.

550 value is on the microsiemens (μS) scale.
Its the most usable in my opinion.

You cant really burn anything at 300ppm or 0.6 EC in veg. 0.3 EC for really small seedlings. 1.0-1.4 EC in flower, less is more.

Good luck! Cheers!

Ya ok. So .5 EC. Makes sense now. You can up it a bit. I normally feed @1ec straight through.
Another thing is cover your pails. When there young there’s no shade on the pails. A piece of card board with reflective spray glued will help 10 fold when there young
