5.5-6.2pH for coco with the perfect balance being 5.8pH.

400ppm at which scale 500 or 700 cal?

I usually run most of my grow in coco at 5.8pH and 600-700 ppm at the 500 calibration!

purple stem can be
Lack of N
Lack of Mg
Cold night temps
Strain trait.

personally I add 100ppm of equal of amounts of Ca and Mg into my nutes first when growing in coco which sees my base water increase from 100ppm up to 200ppm.

then I add all my nutrients and pH adjust the mix.


what is your runoff ppm of your waste water out of the bottom?

you want either a small decrease 100-200ppm or a slight increase 100-200ppm coming out of the bottom at this level you know you’re very nearly at perfect nutrient strength.

HI and thanks for yr reply
Ppm.scale 500 (bluelab combo)
Ph watering always between 6.0-6.2 in veg stage , also some times 5.8 (maybe 5 times).
I do water them,each only a cup of ro water ph around 6.7 and now starting back to green ☻
For sure i dont flush whole the pot , because i do transfer my fabrik pot to final pot without taking out the fabrik , it help me to sample the nutrients by first watering then going for whole the pot.

I feed cal mag at 50% extra dose on top of normal dose. So 1.5ml per litre instead of 1ml.

Then next feed I feed canna a & b. My plants love being fed like this. Try it for a few weeks. They might like it...

I suggest running Canna Coco A & B instead. It has more Ca and Mg than any "calmag" product! I don't like adding extra N when I only want to supplement with Ca or Mg.

Sorry I should have been more clear. I use canna coco a & b only for 1 feed, then next feed is cal mag only with no base nutes. It seems to reset everything nicely. Like a 200ppm (tds) mild cal mag flush to help plant feed better of the a & b feed which is around 600ppm (tds)

What's the temperature inside the grow area? Purple stems is very often a cause of temperature being too low.

Hi
Temp is 24c (light on )
I see they are going lightly greener than going moee red after flush with ro ph 6.7-6.8(only half cup of water each plant )
Now for tommorrow also doing by 1w0 ppm flush then start feeding hy 400 ph 6.0 i decide.
I do also foiliar by 250ppm
All nutrients from dalkine 420 one off the best powder i beleive .
I do have all of his stuff as his foiliar is awesome.
Also i do have add 50-80ppm add cal/mag on my max feeding then going down till flush then rise ppm again to the max point.
Thanks againg for all recommendation❤❤❤❤❤❤

So in other words, you're basically giving your plants teeth before each meal so that they can eat their food and digest it easier. Your philosophy is that it's better for them to eat right rather than to just eat more often. You should do a side by side to test out if that really is better. I just reworded it to sound philosophical hah. But you are basically resetting your plants every other feeding. Thays interesting as it would seem it would be stressful on the plants

Alright I’m thinking about 3k watts, maybe a walkway down the middle and two rows on either side. Let’s stack this room! Hahaha!

But seriously... 2/3 of my strains right now have bright purple/red stems and have since they reached maturity. I dunk my night temps to about 18 and some strains respond by changing colour. Could be?

Flood trays would be a good investment for you. They are kinda expensive, but you will get real sick of those little individual things real quick. And a wet vac. I know you didnt ask for this advice, but I think those two items would make growing much more enjoyable for you

Hi again
I just check them out and they are doing better .
Im also raise the temp around 1c so im about 24.5 light on and 22-21 light off .
Also i do prepare ph 5.8 water (ppm120) for the cleaning .
I just worried WHAT ph is prefer for flushing by coco mix?
I do mix my coco mix by my self and add nitro bat guano also by the end layer and middle and 10%under above .
Best regards
