Canna a + b at 1.5ml/2L and been giving 1.5ml of nitrozyhme per 2l since last week should I up that? I think the light makes it look pale, will get a pic tomorrow outside the room.

Thanks for reply. :)
Saw that you're using Canna A/B (Coco I presume). While it has just enough (barely in my opinion) CalMag to get by, heavier feeding plants can benefit from an additional CalMag. Are you feeding 1.5 mL total per 2 Liter (meaning A & B combined @ .75 mL each), or 3 mL total per 2 Liter (A & B combined @ 1.5 mL each)?

Hey man, I had been giving them 1.5ml a + b for coco combined, I have sinced upped it to 1.5ml of each per 2 liter and she is looking much better, also been giving 0.5ml of clamag every other feed and foliar feeding a few hours before lights on come on each morning with nitrozhyme. When I fed her yesterday I added 3ml of rhizotonic in with the a+b and clamag. Have a look at her now in the pics below, what do you think? She keeps burning on the fan leaves for some reason but all the new growth seems a nice dark green like you said. I had previously burnt the said fan leaves in the early stages.



Thanks for looking :)

Edit: Just seen in your previous post you mentioned the red stems, you are right, it's on the fan leaves. I noticed that last week it does get a bit cold in the room they are in, could it be that? Temps when lights go off goes down to about 18-19 degrees celcius, when they are on they are around 25-27.

Your plants are looking a little better. The yellowing on the new top growth seem to have went away. Yeah I kind of figured - .75 mL per L is way too low for your size plant. You should be closer to the 1.5 - 2 mL per part, per L. That's 3 - 4 mL combined per L. Your dose of 3 mL (A/B combined) per 2L (which = 1.5 mL per L) is still kind of low. Stick to it if that's what your comfortable with. Yes cold temp can cause red/purple stem, but so can mag deficiency, pH fluctuation and genetics. You have a number of other underlying issues, it's quite hard to determine exactly what's causing it. One thing's for sure - when the temp drops too low and your root gets cold, it will have problem absorbing magnesium. Did you get the mag def first or the cold temp? 19 c (66 F) is pretty low - ambient temp, not too much of a problem but root zone, can be somewhat of a headache. However, 25 - 27 c is spot on. Plants (veg) thrive in temps around 72 - 82 F (22 - 28 c) with 75 - 77 F being ideal. Throw in a small space heater to warm up your grow room at lights off or a heat mat under your pots if you have to. You should see a difference within 24 hrs, if cold temp was the culprit for your mag deficiency. Keep up with the higher feed dosage. Your plant should green up in no time. Rhizotonic can help in certain circumstances, but it's not a magic potion.

I use just canna A/b In coco and clay Balls,No need for Rhizatonic un less you have a Problem or Roots are not too Good ,But from looking at this Plant it doing just fine,Perhaps a little light ,Bump ec up to around 1.4.I used to use there full Line,But aint done for years ,and my harvest have not gone down ,still get around the same ,Canna a/b Big Bud Advanced And Pk 13/14 canna the only 3 i use

I've been growing in canna coco pro plus for past 10 years and never ever used cal/mag as i use Vitalink Coco Nutes Classic, and not the new shite, just plain ole grow, bloom, buddy and pk 13/14.
I never was one for the bullshit bud enhancers, well i was and i did that many moons ago and they all did jack shit compared to the added fuck off costs involved, i use the K.I.S.S. Method and never have any issues.
