Hi all. I have started to notice that some stems a...

Hey there so just a couple things...1st the nitrogen claw, i think if you back off the N intake like you mentioned it should calm down, it didn't look like you'd gotten to the point of no return. Regarding the red stems etc. No one seems to have mentioned that a phosphorus deficiency will usually cause this, along with the dark coloring on leaves and then into having some spots as well. Often mixed up with other deficiencies. But you mentioned doing a ph'd flush for a week...maybe with her headed into flowering it threw her off since they're very P hungry during those first weeks of flowering? I'd up the tiger bloom to a teaspoon and watch for a change. I have some sour stompers who were having excessive red and as i increased the tiger the red/purple became far less intense. Good luck with the grow, don't give up on her yet there's still lots of time to show what she's got.✌️

The simple answer here is to all CalMag to your nutrient solutions mix up . If you add CalMg to your plant nutrient line up and its still ends up being like that its a genetical trait carried over from a parent genetic . This happens sometimes I experienced it in my GG#4 grow it was pretty cool to see :) . I hope this information helps you determine better what your issue is wether its genetic trait or CalMg deficiency . Over all its looking pretty good and I wish you the best of luck on the remainder of your grow !! - Happy Growing!

Yeah the purplish at that stage is due to a magnesium deficiency ( cal mag are not optional with coco, each watering require some ). Oh and by the way I've been growing the Cream mandarins fast version for more than a year and this strain have pirplelish colours on the stems / leaves and buds during flowering ✌️🏼

Man those girls look fine and healthy lol.! I wouldn't worry about that reddish tinge on the stem I get that on every grow and it hasn't affected any of my harvests... Yes, it says ima "newbie" but only on this site because I just did an account here a few a few months back.! I've got many years experience growing my friend... I wouldn't do anything to try and stop the red on the stems bro just do what you been doing and get your nutes dialed in and you should be set...! Also, don't add any Calmag unless you see a Calmag deficiency because you do not have a Calmag problem at this point... My last harvest yielded 17.4 oz and i had that beautiful red tinge on my stems throughout the grow.! I really think its genetics

i mate.. i wouldn't stress at all about that. i think that its genetics related since it cream mandarine has chemdawg in it..but like stick said, stay at a sweet spot of 6.1-6.3 ph. i was at a canna seminar a few weeks ago and mr.Peter said that solution temperature should be around 18-22c, i was also shocked by that info..but from them im sticking to it :D don't feed calmag already because there arent any real signs of calmag deficiency (deficiency manifests on leaves first, then on the stems).. if all the input is correct in your diary then i think your safe..but try to lower the ph cheers :)

Hi @AutoCrazy! There are a few reasons - other than genetics - that could explain why your stems are turning purple: a wrong pH range, a cold air temperature, a cold solution/roots temperature, a Magnesium deficiency, and a very high or very low relative humidity. In your situation, I would start by re-calibrating the pH-pen and stick to a 6.2 pH for the next waterings/feedings (it is the sweet-spot in soil). Then, I would increase the relative humidity up to 50% for the next weeks until late flowering (35% would be okay for late flowering but it's way to low for the vegetative+preflowering stages). I would also double-check the solution's temperature, it takes only 1 cold watering to get purple stems, so make sure your waterings are not below 20°c and not above 23°c (~68-73°F). Finally, I would add a slight dose of CalMag into the next feedings, that girl is probably hungry for Mag. The affected stems won't be green again but the coloring should stop if you find the right way to fix it. Hope this will help, keep us up-to-date and happy growing! 👊
