IMPORTANT excess/deficiency? What's happening? Flowering is in danger

HAPPYWEEDS
HAPPYWEEDSstarted grow question 2 years ago
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak

I am gonna say your starving the plant. Feed off plant size not a chart. I do coco grows regularly. Feel free to see how much I feed at the same time on my plants. It wants nutrition badly.

Up the calmag. Raise your lights. Add in some stress reliever and you’ll be fine

Wow pretty colourful leaf but not in a good way I have a plant i have neglected that looks like this atm I can only assume its down to a lack of cal mag to start and then from then on that will stop them uptaking alot of beneficial nutrients so i would start with trying to sort that out first then if you have some kind of macro feed id get that in her too I would just go by the bottle the yellowing could be down to a lack of nitrogen but even i must admit it doesnt really look like that im not actully sure this is a tough one hmmmmm yes very interesting sir stumped me sorry maybe another grower has more information or advice but thats my best shot lol 👊

@gmslave thank you very much. Run off values are 0.9 EC. Should I decrease feeding to 600 ppm?

With photo plants in coco, we don't go past 800 ppm, 1.6 ec usually. With autos we don't go past 600 ppm usually. What you have is lockout and you need to run ph water through until you lower your ppm
