Help ID this deficiency!

Привет, друг! 👋 Это идёт дефицит фосфора, это его начальная стадия! Ножка листвы имеет слегка красноватые полосы и цвет с красным оттенком. 👆 Я не вижу ваш дневник и мне тяжело установить причину этого, но я могу дать пару советов для решения этой проблемы: - проверьте свой ph , он должен быть в пределах 5,5-5,6ph (для вегетации), 5,7-5,8ph (для цветения). 👆 - внесите добавки grow:bloom в отношении (1:1- для вегетации), (1:3 - для начала цветения), (1:4 - для цветения), (на созревании добавку Gro не используем, даём только Bloom или Ripen)! 👆 Удачи, друг! ✊😇

Hmm having trouble editing my comment or adding photos... not sure what to do?

Hey Gaia, Thanks for the quick response. I will add photos of the entire plant asap for you to review. The grow medium are the inert clay balls, i forget what they are called, its in a 10in net pot. weve been keeping ph locked in at 6.3 over the past week+ since trying to combat the deficiency.

It does look like a calcium deficiency at a glance. You know it’s calcium def if those markings are on leaves that are growing fast and/or in direct light. Would be good to see the whole plant for diagnosing but none the less, this def is more likely to appear if using RO as it is stripped of all elements, of growing in coco as is tends to not absorb micro nutrients very well, could be locked out if ph is too low, like bellow 6.2, or too much potassium will also lock out calcium. If growing in coco make sure you supplement with extra cal mag, if ph too low, flush with ph balanced water of 6.2-6.5 and ensure you are using a cannabis friendly nutrient to avoid unbalanced nutrient ratios. Hope this helps! Cheers 🍻
