Coco Nutrient Ratios

[peacepipe17]

Ive done enough reading and my head hurts. Ive compared other products to mine etc but Id like an opinion from other coco growers on my nutrient ratios..

Specifically K:CA:MG (my understanding is this ratio should be 4:2:1)

I run: Botanicare CNS17 @ 17ml/Gal, Silica @ 5 ml/Gal, Fulvex @ 5ml/Gal

N - P - K - Ca - Mg
97-42-126-97-50

This is added to tap water that starts slightly over 100ppm @.5 conversion

Ive toyed with the idea of adding sweet (5ml/Gal) again which boosts the Mg to 70. but the ratio of Ca:Mg seems better above so Ive also thought of using the Hi-Brix Molasses instead (5ml/Gal) (extra K in it) which would give me these totals

97-42-168-97-50

which is closer to the 4:2:1 ratio I mentioned earlier. If I were to add Hydroplex (2ml/Gal) I would get

**97-67-198-97-50 (with Molasses) and honestly that looks perfect based on my knowledge**

97-67-156-97-70 (with sweet instead of molasses)

The reason I am trying to get my ratios right is I have seen an issue with either K or Mg every grow usually mid flower. A little about my grow: (2) 1k hoods, 20 bushy plants 5-6ft tall in 7 gallon containers in a 10x5 space. I top feed in smart pots.

Part of my confusion is with the K specifically. I believe I have the most of the nutrient profile correct but I know canna nutes tend to be really low in K because of the amount present in the coco coir. If someone could shed some light on the K levels as well it would be much appreciated Ive done enough reading and my head hurts.

I wish I had some insight for you.
I'm in my second coco crop and would love to hear someone with some experience chime in :]

Look into Jacks professional in the coco thread and the other threads. DJM's coco trees thread is magnificent. I know its a pain to read and read and read but it really is the only way to fully understand whats what. I use the 3-2-1 Jacks calnit epsom. from start to finish works beautifully and is cheap cheap. I tend to flush a lot more than people do it seems. But I was having issues spawned by broads so if you stay on it you shouldn't have a problem. I just brought my plants back from the dead basically. Heat treating damaged bad, broads damage and some drying out. If you stay vigilant you will get there.

I don't have all the numbers in front of me and I would just go look at the coco coir threads for the posts. So you might as well just keep at it. I went through the same thing bud. Just take your time. You'll work it out.
