Wondering if this was early sign of potassium deficiency.

[Clearbluesky]

Just wanted if this was early sign of potassium deficiency growing in Cocoa ph6.0 only on about 15 leaves. 2 and half weeks into flowering

Think I'm going to add some calmagic to my reservoir, because I backed off the calcium nitrate 2 weeks ago. And started adding more magnesium my Epsom salts. But I think I cut too much calcium out I think my plant still need some so I will give that a try.

Looks more like heat issue and possible beginning to lock out… i wouldnt mess with ratios to much.

How are you watering these and in what size m/type of pots?

 

[Aqua Man]

Too much N imo but not enough to say anything definitive yet

I'd dump the res, flush and start over so you know whats in it.

Tent does have very good air movement and temperature is 79, they are I 3 gallon air pots 70/30 coco perlite, getting feed 5 times a day at 40 second's each feed and getting 20 percent run off. Got a 20 gallon reservoir so went a head and added 17 ML of calmagic to it and only raised ppm 60 for a total of 650 ppm with PH 5.8

When I mix it in 5 gallon bucket I add 250 ppm of Base and 250 ppm of Epsom salts and 100 of calcium nitrate. I do that over and over until I fill my 20 gallon reservoir works good for me that way. Then pH it.

 

[Clearbluesky]

The leaves with the problems are where there is a lot of air movement on them.

Here's new pictures of plants, they like how I have been feeding them.

What nutrients are they? Seems like a lot of magnesium

Well they look good so i wouldn’t go chasing ghosts to far… it may well be windburn

Yes using master blend, you you cut back on the calcium nitrate you replace it with epsom salts just reverse those two numbers around from veg to flower so if it was 12 base six Epsom salts 12 calcium nitrate once flowering hits you go 12 base 12 Epsom salts six calcium nitrate.

Ok, all I did was give them some cow magic 70 PPM worth.

I have to disagree. Cal and mag are not interchangeable like that imo. They gave a very specific ratio in relation to eachother. If you reduce cal you shoukd reduce mag

 

[Clearbluesky]

The plant that's not really flowering that good yet does have anything on its leaves. Looks good I think it is the wind burn

 

[Aqua Man]

Ahh i see what your saying now your intentionally changing the ratios

I think you are correct. The plants look good overall a d chasing ghosts can often times lead to manufacturing problems

That's just the recipe for master blend three parts 12 6 12 in veg and in flower it's 12 12 6 for 5 gallon bucket been growing that way for two years

 

[Clearbluesky]

When using master blend I don't even use calmagic, just thought I would try it see if it would do anything.

Here's recipe, that's for veg
