Plants exploding, but, looks like calmag def???

Transplanted from tiny cups 7 days ago cheap soil, fed only water and neglected. No visable Roots when i transplanted.

Now in their next size up. Went from soil too 100% premium cyco coco.

Feeding hydroponic nutrients, 5.8 - 6.2 ph. 3 waters so far. Now feeding 5.8 ph.

EC and ppm of tap water is 0.7ec and 350ppm.

I double the 350ppm = 700, divide by 1000, brings it too 0.7 EC.

Nutrient calculator tells me targrt EC of 2.

I watered
1.2 ec with 6.2 ph
1.2 ec with 6.0 ph
And now im cutting back too 5.8ph and (1EC or 480ppm)

They went from stunted little runts, too thriving, in 7 days where i topped it the new nodes are 1 inch long with more nodes coming off that. The whole pot is full of healthy strong roots, when i couldnt even see roots when i transplanted from.their tiny pots just crumbly black dirt.

First time with coco and im blown away by crazy growth.

Strain is kalishkanov by ghs.

I see a couple spots and slight discolouration on leaves. Wondering if anyone had a clue ?

Likely developing magnesium deficiency

My opinion, it's the fresh coco causing a very slight magnesium issue with your plants. Still looks fine to me, should push right through that no problem. That spot and small "kink" in leaf I wouldn't worry about, unless more leaves start doing it too. Could be anything, maybe you knicked that leaf doing LST?

Could be fresh coco, it says on the bad its washed, buffered and all the rest, says its premium ready for cannabis.

If it is the coco, would it be a deficiency or a toxicity. Its on a couple leaves but it is slowly developing ive caught it early.

It is only appearing on the fastest growing and biggest plant, this plant is the most vigerous.

Maybe its using cal mag faster then the rest.

I water ISN nutirients at 1 EC, and 5.8 ph.
Grow a and b
Seaweed
Microbes
Amino gold
Silica

But no cal mag or anything like that.
Water if from tap at 0.7 ec by time i feed and add nutes its 1ec which is my target.

What about calcium ? Do the 2 go hand in hand. You can see in my other comment the stats of the water and food they get

None of the others really have it jusy this one i think it is using the most nutes?

Nah, calcium issues start to look like freckles along the leaf spine, this looks like faded discoloration between the leaf margins typical of magnesium deficiency. I think personally it's nothing to worry about right now, unless it progresses. It probably won't.

Calcium deficiency shows on the newest growth. Magnesium on older.

I'd shelter the roots somehow from the light. They don't like it so much.

Only temporary probably have too put in final pots in a couple weeks as they will be fully filled with roots by then

Thinking 4 plants in 10gal pots. 10 percent perlight rest coco

With clear pots/cups you are asking for algae to start to grow all over the place..

Haha funny, i know thanks bro, i really just do it i like seeing the roots haha but only for a few weeks at start never really had problems, going too use 4 massive fabric air pots under 3000 watts with timed 2 or 3 feeds a day. Suspended off the ground for max air, and max water. Water goes too waste.

3000 watts of what? And is this actual wattage?

Yeah hps, 2500 watts worth. N I'm going too use a actuall 600 watt LED potentially and compare the yields from old school too new school n growth and just see if I actually like it

Hey guys merry Xmas, and new year.

I will post pictures in a min. My deficiency is getting worse.

And it's the holidays so shops shut for a few days. Fed and watered again last night ec of 1, ppm 500.

And pH 5.8

Looking for help ♡ thanks guys

I dunno if I'm doing this right.

The way I figure out my EC is also I just measure ppm.

Ppm × 2 ÷ 1000 = my EC

My tap water is 350ppm, x 2 ÷ 1000 = 0.7.

I only target too achieve 1EC, so I only add 0.3ec from nutes.

Wonder how big a difference filtering the tap water would make too plants health. If I could get ec down too 0.3 I could then add 0.7 ec from nutes too achieve target of 1 but with nearly double the nutes???




This is how I read in a article too do it. Seems complicated but I think I'm along the right track. This photo is the nutrient calculator off my nutes website, it says too target at 2 ec.

I was doing 1.2 ec but thought it might be too strong, as the growth is pretty insane it's growing so fast so I backed down too 1 ec and ph of 5.8 I might try raise EC as it gets bigger and stronger. Might get a filter as well too bring tap water hardness down so I can add more EC of nutes ? Vs feeding it less nutes and whatever chlorine and fluoride and iron that's in the water

Anyone able too help

No one ?
