The only one of the answers are right - @SpinerGrow. Its defenetly Nitrogen deficiency wich gose farther on 7 week and cause the Iron deficiency as well. All that happend just because your pH is to low for soil substrate. You should rise it at least to 6.2, wich is the lower red line pH in soil before you get a nutrient lock. The soil pH range is 6.5 - 6.2. Advaced growers start with higher pH at veg and gradualy lows it down as it gose in to flowering. My recomendation is to rise the pH to 6.4 and to spray foliar Alg-a-Mic gently on the affected leafs. As well i would make some Urtica(Nettle) tea, wich is the best sourse of Iron. All you need is 250 grams of fresh nettle leafs and 1 litter of RO water. Put the leafs in the water and let it soak for 24 houers in dark with room temperature. Add it to your solution and spray foliar. But Alg-a-Mic will do the job as well. Happy growing Bro!

Hello ! No cal mag def here , the purple stems must be a genetic trait of your strain. Agreed on the N def diagnosis and sorry for Valhallas but the yellow veins is not a Cal or Mag def sign. I can also see that only one of your plant is affected so maybe she needs more nuts or maybe the roots of that one had an issue earlier (but it's just a guess) or it could be an early scenescence ( the final an natural yellowing of the plant to show you that the harvest is soon). I hope it will help you 😁👍

Hey there @happygrower420! Looks like you had a magnesium deficiency and were experiencing a Nutrient burn in week 8 (see the burnt tips). This has gotten worse here in week 9! If you plan on taking her for longer than 2 more week then you may want to look into a flush to clear out the soil before adding the deficient Magnesium. If you are not planning on going for longer than 2 weeks then I wouldn't worry about it as you should be starting the final flush shortly anyway and it wont effect the harvest results. Best of luck finishing this grow out! 😎

It must have been as you definitely have magnesium deficiency showing with those purple stems.

Isn't the most common cause of red and purple leaves and stems phosphorus deficiency? I don't know if I saw anyone mention that in your Answers. However if you're feeding Bloom nutrients and don't have lockout, and the plant is over all fairy healthy looking then it sometimes is genetics based. Lots of strains have purple red pink stems as part of their character.

Hi @HappyGrower420! The purple color could be a sign of a Magnesium deficiency, but the cold temperatures you're having at night and the LED you're using could also explain this phenomenon. In my opinion, your feedings are responsible for this. You are giving too much RootJuice, too much Alg-a-mic, and not enough BioBloom. Now that you're in week 2 of flowering, the stretch should have ended, so you can stop BioGrow intakes, but your baby needs more P+K, at least 3-4 ml/L. I've been using BioBizz for a while, and had great results following this feeding schedule, made for autos: http://www.420magazine.com/gallery/data/500/Untitled124.png. As you can see, you should be giving 4ml/L of BioBloom, 4ml/L of TopMax, and eventually 3ml/L of BioHeaven. Stop RootJuice and Alg-a-Mic now, try to stick to this feeding schedule, and you should be fine. A good flush before applying this new feeding routine could help to get rid of extra nutrients and make sure you don't have any salt buildup in your soil. Hope this will help, keep us up-to-date and happy growing 👊

You've been giving cal mag at 1 cc per liter for weeks (that's usually around 0.5EC or 250 PPM worth of it), and that's enough, so you have neither calcium, nor magnesium deficiency. Calcium deficiency shows on the tops leaves as rust spots (my first diary had that, check it if you want, the one with the colombian gold); magnesium shows as interveinal yellowing, not yellow veins (which I don't see in those pictures), sometimes accompanied with purple stems, although for some reasons that I don't remember LEDlights have a tendency to promote purple stems (with no ill effect). What I can see is some lower yellowing that indicates some Nitrogen deficiency, quite normal for a plant at the stretch phase, I would give it biogrow 2 cc/lt.

I can tell you right now your suffering from calcium and mag deficiency's your stems are very purple as well as the veins in your plant are turning yellow which leads me to believe you have both . A simple fix you can just add cal mg to your solution and this problem will slow and go away all together . You're also suffering from slight nitrogen deficiency but i wouldn't worry to much about that at this stage seeing as you started flowering , I would just give your girls a good PK spike and you're going to be rocking and rolling more so then you are already ! Sometimes leafs that suffer from nitro deficiency don't come back to full green you can just clip it off and everything will be ok :) All in all you got very little to fix here I see you already have all your solutions just make your CalMg 2ml per litre of nutrient mix and adjust your to be more bloom oriented so add 1ml of bloom and you will be right back on track . I hope this information helps you on your quest to the finish line ! -Happy Growing!
