If your plant's leaves have small brown spots trimmed in yellow, this could be a sign that it has leaf spot disease, which is a fungus or bacteria that feeds on the leaves. Hopefully I answered your question and remember Happy Growing and Free your mind one puff at a time.

I would say maybe a little calmag needed. Older fan leaf can show this first with L.E.D .

Apricot Oreoz... the Unhealthy RuntDoes anyone have any experience with growing Anesia's Apricot Oreoz seeds? The plant seems to be experiencing a Cal-Mag related nutrient deficiency that the others are not. All plants are being grown under the same conditions. Any suggestions?2 years ago

First time grower - How are we looking? This picture is right after feed. Previous Feed was Armor Si 2ml/gal, Calmag 5 ml/gal, Coco A/B 8ml/gal, Cannazym 10 ml/gal, Rhizotonic 8 ml/gal. That was 2 days ago. Slight yellowing of the leaves? Nitrogen deficiency? OK? Need Calmag?Week 5

Hello weed doctors, I need help identifying the problem and gathering advice how to enhance my second grow. It's only day 29 and my girls are sick, whI'm in biobizz lightmix. Started biogrow on D24, the dose was 50% in 400ml water. Until D24 only rootjuice. Yesterday gave 1400ml each, with 100% biogrow, pH6.4 EC 1.1. My water is hard pH7.7 EC0.8, so I wasn't adding calmag yet. There was 400ml runoff EC 1.9 - why? What do I do?a year ago

Yellow spots between veinsIn several weeks my plant has yellow spots between veins, but it starts from the top to the bottom of the plant: old leaves seems fine when the new ones are spotted.I thought it is Mg deficiency, fed my plant foliar with epsom salt, added CalMag to the feeding, but no luck. WTF?Week 6

Top leavesHi Growmies,
Two weeks ago i noticed that there are some yellow stripes appeared on the top leaves. The PH fluctuates in DWC can this cause some micro nutrient deficiency but I don’t really know.
Do you have any ideas what could be?
