Leaf identify

spankyxvistarted grow question 3y ago

This is my test plant. Please help identify leaf. This is nute burn? Top of the plant look just fine. Should i worry? Before this happen I feed her 570ppm and try supercropping on main stem (twisted). She fine with 660ppm in the past so I confuse what is the problem. Thank you.

Symptoms: older leaves at base of the plants turn yellowish between the veins while the veins stay green.The green veins look like green stripes on a yellow leaf. Make sure there is no small dark structures on the leafs. If there is it's a fungal infection,growing in yellow tissue. From the pictures I don't see this.Your young leafs at branch tips look normal. The book and I say nitrogen (N) or Magnesium (Mg) deficiency. A deficiency is when don't got enough and a toxicity is you put to much nutrients. Add some Calmag with iron. Well hope best my fellow grower. Best advice never stop . Use everything as learning and pass on what you learn so we can have good medicine. BLESSINGS ON ALL U GROW AND HARVEST MY FELLOW GROWER!!!

And quick question did you buffer your Coco? If not you found your problem. Coco steals by absorption of the CALMG.

Avant de parler de carence je pense qu il faudrais savoir si le ph de l'arrosage est respecté, car le fait de ne pas contrôler le ph empêche la plante d'assimiler les nutriments donc crée des carence😉

Calcium deficiency?I'm not so sure if it's calcium deficiency, what do you think? Watering 100ml of water minimum. Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free. Should I water her more and add more calmag or is this a different deficiency?

Leaf issue in Wk 6 Hi I am having a leaf issue late in week 6. It’s been coming on a while. I’m wondering if the ph is out or too high ppm. 7 gal pots in a Scrog, it’s hard to test runoff. I’m starting to flush now so does it matter as much as long as ph is good? More wondering for next run. Thanks
