Leaves, rust dots, yellowing margins
marihoochistarted grow question 2 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 leaf tipsHello,
I think I have a slight over-fertilisation.
Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

I did some LST which the plant handled quite well. I am seeing leaves turning yellow starting from the inside. Is it missing nitrogen? Thx in advance..

The clone has bad leaves. Need helpTell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.

Natural or Problem?Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.
