Leaves, rust dots, yellowing margins
marihoochistarted grow question 3 years ago
These leaves look like torture, are they getting too much or not enough? Brown rust dots, yellowing margins that turn brown; petioles are purple.

Looks like issues in the root zone. Test your runoff. I would bet the ph is in the 4.5-5 range. This will affect the uptake of nutrients the plants need in flower.

Did those leaves come off the top or bottom of the plant?

Looks like a calcium deficiency. Coco always needs extra cal mag. The other option is your ph in your coco is getting out of range. In heavy flowering in coco for myself my ph will rise causing lock out if I don't heavily dose it with extra potassium and phosphorus to maintain and stabilize it. Lack of enough nutrients is what does it to me. I would run a ph 5.8 water through till run off. Get a test reading of ph. If it is 6.3 or up there is the problem. Ph is very important in coco grows, but results are strong.
Feel free to dm me if you need more assistance. Happy growing 🌱

Yellow lower leavesLower leaves are turning yellow. She just started her second week in flower.

Should I trim off the damaged leaves?Should I trim off the bad/damaged leaves or leave them on? I'm not sure if it will help or stunt the growth even more(I don't know if that possible at this point but still). Do they even have a function after they got damaged the way they have? Please check my diary for picsLeaves. Color - Yellow

Tips turning into yellowWe started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)3 years ago

Leaves with yellow spotsWe have find some leaves with yellow spots in them. The tips on new leaves are also turning yellow. Is this nutrient burn? Searching online I found it may be due to pH fluctuations, although we use pH controller with ferts (before ferts only bottled water pH ~5.5).Leaves. Color - Yellow

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10This is my second attempt at cocus
I work with Plagron nutrient solutions(Coco Nutrient)
I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!Leaves. Edges burnt

Nitrogen Deficiency, Nitrogen Toxicity or normal flowering behavior in an Auto?Lower leaves that are the largest & oldest are wilting & yellowing about 2 weeks into flowering. I started adding nutrients after 4 weeks in Ocean Forest soil. More details and pictures in my diary. Fast Bud #2, Week 63 years ago
