It seems that no body really reads the whole posts, and everybody just write what works for them or say just general info regarding cultivation in coco but no body really knows what plants need in coco..
Are you using their Coco formula? Does the bottle happen to list the Mg content? Couldn't find it on their website. They listed CA at 4.5% for the Coco's. Also do any of your nutes already have silica in it? Too much silica (which usually has a lot of K in it) will lockout Ca and cause problems like you are seeing. If you continue seeing problems like this and are not using base nutes on the first water I would: 1- start using the base nutes from the first feed and on making sure they have exactly what they need. 2- with RO you "might" have to add a little
calmg at the very beginning to offset coco locking those nutes up when it's fresh. That also comes down to the brand. This is something I never practice cause I usually hit them pretty hard day 1 and on. Might be something you are running into. Just don't play into all the witchcraft about coco. It's a medium like any other medium. Also remember K.I.S.S. Less is more.
Thanks alot for your comments, I mean no insult to any body but
It seems that no body really reads the whole posts except you , and everybody just give some jeudges and write what works for them or say just general info regarding cultivation in coco but no body really knows what plants need to be coco and no body can define the probleems when it happens in coco except if its very obvious cal or mag for sure (can be my case but the symptomos are mixed between dien tips in some plants, some other get looks alike mag, some other one get narcotic dots like cal etc)..
Am not an experience grower but am also not a newbie. Am not overwatering and I watch all the other factors....
Indeed the silica might be a factor ill stop this for now, thank you for reminding me by the silica thing..
Here is some pics of the nuets I usualy use, however I used just canna start till now.
Coco A
4.5% calcium
Coco B
(they dont mention how much mg exactly is in)
Whats strange that they advise ph of 5.5 on thier website! I really doubt if I SHOULD adjust my ph to 5.5!
Also this is a good read from canna website
What is the difference between soft/hard and/or bad water and what can you do about it?
Soft water has an EC level of below 0.4. With CANNA
CALMAG AGENT you can raise your EC level to 0.4.
Normal water has an EC level between 0.4 and 0.7. It contains calcium, magnesium and bicarbonate to stabilise the pH. All CANNA products are designed to work best with this type of water.
Hard water (EC>0.8) contains more calcium and magnesium than the plant can handle. When you’re growing plants, the best way to treat this kind of water is to use a reverse osmosis filter and then mix your hard water with the R.O. water, until you reach an EC level of 0.4. Or, more easily, you can use 100% R.O. water and then use CANNA
CALMAG AGENT to raise your EC level to 0.4.
Bad water (EC>0.8) contains mainly sodium and chloride. These two elements block the uptake of nutrients and can even become toxic to your plants. With a reverse osmosis filter, you can remove both these elements. But making a mixture of R.O. water and bad water will not bring in enough calcium and magnesium, only bicarbonate to stabilise the pH. Make a mixture of R.O water with the bad water until you reach an EC of 0.2 and then add CANNA
CALMAG Agent to this water until you reach an EC level of 0.4, or use 100% R.O. water in combination with CANNA
CALMAG AGENT until you reach EC level 0.4
How can you test the difference between hard water and bad water?
The best way to find out is to:
- ask your water supplier
- have your water analysed (done by an official laboratory)
You can also test the water yourself using an EC meter and 2 small tests based on colour indication. First, measure the EC to be sure it is not
SOFT or
NORMAL water:
- EC 0.0-0.3: the water is SOFT
- EC 0.4-0.7: the water is Normal
** conclusion.
Thier nutes suppose to work within the 0.4 and 0.7 ec
If some strains require more cal mag and I see guys who hit thier ppm of cal mag to 250 and some others up to 350 ppm of cal mag..
And since I raised my base for the two groups to 350ppm of cal mag the probleem has stopped,While I have increased the total ec to 1 instead of the 0.7 ec first feeding!
Thats why I doubt now should I continue with the 350 cal mag next feeding also or drop it to 250 ppm and give an ec of 1 again?
Should I continue still canna start or transfer to plagron coco?
