Plant stems staying purple - Page 2 - Growing in Coco Coir - International Cannagraphic Magazine Forums

Like alrdy tried to explain in the other thread: High ph in your Coco. To much Ca, to much N. Mentioned by BakedBandit: To high EC for little ones, go 0,6 to 0,8. Theres a mg def (light clouds on your leafs) since the Ca from your calmag repressed your mg in your medium and the high ph locks out P (blue purple lower big leafs, purple stems).

Use the (Canna) Coco Test to be sure (or buy a soil ph meter): Take 250ml vessel, fill 100ml deionised water, fill to 250ml with Coco samples from your pot. Stear, let sit for 30min (Canna says a night, but thats not rly necessary), filter, measure ph (and EC if you want). Ill bet its near 6,5ph, definitely over 6,2.

+Use Cannazym with Canna AB, it pushes your NPK ratio to more PK (adds 0-2-1 whats
about 20mg p and 20mg k) whats definitely needed and always adviced in Canna shedule. Throw out Calmag! No additional N, Ca and Mg needed!

You have a Mg def. push it up to 70 ppm and voila

I had this same problem using canna nutes. flush again and then use a lucas formula ...get some flora nova. stuff works great and it really cheap it will give them everything they need to snap out of it. you can use the rest of your canna when they get bigger and snap out of it

Those stems are dark.

Some of the strains I flower have purple on the leaf stems,
no worries for me, but yours seem fucky.

Keep us posted on the remedy.

Looks like a 'trait'. I worked a certain breeding mission for years (Sweet Blue male x Johnny Blaze fem) that had DJ shorts special sativa pheno blueberry male as he grandfather on both sides and a purple stems were more common than not.

Purple is a phosphorus deficiency, usually caused by a Mg or K excess. Often looks like a Mg deficiency too! Your EC is already too high.

Just foliar with pH down (p acid) at 0.4%

And flush!!!!

Sometimes...... Some strains do it naturally
