What deficiency is this?

[Steve Jobs]

It’s only on 1 plant in a 2 plant tote, on the bigger fans. I’ve been told calmag but I’ve added more and the other plant looks fine. Looking for opinions. I can add more calmag if I need to. Next grow I’m going single pails instead of 2 plant tote.

These pictures were the first run in. After I clipped this leaves it came back 2 weeks later.

These last 2 are off a leaf I just clipped.

Like always Steve...having what yer feeding, amounts and pH is always beneficial


I'd say Alien Spawn myself...but I always side on caution....


How much calmag u using, and what brand

Remember, effected leaves won't get better, so watch new growth

Dwc, using Remo grow, micro and calmag. Ppm is up around 5-600 using ro water. Probably an even split between the 3. 25 ml each in 6 gallons or so.

Ph is always between 5.7 and 6.2. I move it around to get different ranges of uptake.

So.....

How much calmag

 

[Steve Jobs]

Around 25 ml in 6 gallons. I don’t ppm per nute added

 

[GrizzWald]

Only ml per litre, can double that...

Ok I didn’t want to lock them out with too much. I’m switching to flower New Year’s Day so I’ll bump it up. I’ll go pretty close to reccomended nutes on the calculator.

 

[Chris Scorpio]

On calmag and other additives, not base nutes, better to run 100% suggested

Calmag is very important in RO water

I've ran 150% in my Hempy a lot
