Start of week 2 of veg n noticed this,

[SkyFox]

1100 ppm 78°f, 62% RN steady coco coir royal gold tupur , 1 feed a day, spiderfarmwe 4000 - 29in from pot rim
I noticed this slight yellowing stain on my babies
They r in week 2 day 1 of veg

These r the pics

 

[kovidkough]

calcium lockout , why such high ppm?

how much calmag r u running

 

[SkyFox]

Like 1 ml per gallon
Ph is 5.9

 

[HydroKid239]

bump to 3ml/g

 

[SkyFox]

But .. so its not cal/mag toxicity? Does it matter the run offph in coco?

 

[coherent]

A little more cal-mag and about half or less as much nutes.

 

[SkyFox]

bump to 3ml/g

Im also using sensi coco grow part a&b

 

[SkyFox]

A little more cal-mag and about half or less as much nutes.

So i dont need to flush right?

 

[SkyFox]

Cuz rhwre isnt any nute burn or anything

 

[SkyFox]

They 2 in week 2 of veg in 2 gallon pots n there is roots already at the bottom of pot... thats cool and all but i just wanted them to finish in 5 gallon pots

Check your run off ppm's.

 

[kovidkough]

your feeding the calmag to coco not the plant. the more surface area of coco the more calmag. larger pot larger calmag, 1gal pot 1ml per gal, 3gal pot 3ml , 5gal 5ml

your coco is taking all the calcium to compensate, if you add more it will achieve equilibrium

Coco basics:
Feed daily with light nutes to substantial run off using a pH around 6.0........at least twice a day in flower.
Never use plain water.......always use nutes.
Never let it get dry.

Personally I would flush them with 1/4 strength nutes and start a daily feeding schedule with weaker nutes.

My runoff ppm is the same as i put in, maybe just 20ppm lower

Whats the ppm range per week veg and flowee that i should aim for?

 

[kovidkough]

200-300 seedling
400-600 veg
600-1000 late veg/ bloom

all strain dependent, some eat more some eat less autos require a lower scale

I don't have a ppm meter so I can't answer your question.

If you go to www.cocoforcannabis.com they can answer your question. It's the best place to learn the correct way to grow in coco IMO.

Wait, first, what is your starting water like, tap, ro, starting ph/ppms? 1100 is very high for two week old plants, these are clones right?
