What's the problem with the leaf?
RFarm21started grow question 3 years ago
What's up with these leafs? lack of ca/mag ? I'm in the 4th week of flowering.(autoflower). This plant is a little stunted from the beginning but only now do the leaves look like that. two days ago I reduced the dosage of biogrow and bioheaven a little
Thanks for the help!

Mmm I’m thinking calcium or magnesium deficiency.. hard to say as they kinda overlap sometimes in symptoms.. looks like you’ve got N excess as well by the looks of the darker green shiny leaves in the video - could be wrong about that but that would explain a calcium deficiency.
If your foliage does indeed look darker green and glossy almost I might flush or eliminate N heavy nutrients completely. I’m not familiar with the “bio” line up of nutrients to expand on that further, but week 4 of flower you can pretty much cut N completely outta the equation.
Good luck 👍

I'd put money on a ph problem, in the growing medium.
A quick slurry test will give you a rough idea.

Ezzjaygrows obrigado pela resposta! Penso que seja isso mesmo, próxima alimentação vou diminuir mais um pouco o nitrogênio e aumentar a dose de CalMag

That looks like water/light burn. Have you done a foliar or IPM spray lately?

Do these random spots mean nutrient burn/deficiency, or is this normal?I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?

Brown Leaf Spots help!I have a serious problem with two of my girls and I can't figure out whats wrong.
The pics attached show the brown spots that have now spread to a good 60% of the leaves on each plant. I've defoliated as much of it as I can and its now affecting even the sugar leaves. Any ideas?

Is this a calcium issue?I noticed some discoloration on several leaves but not widespread. I think it is calcium deficiency but to make sure. Whatever ails her, a more informed opinion would ease my mind. Also, if it is a calcium issue, would raising from 3 to 5ml/gal of calmagic resolve it? (DWC)

What could this be? Deficiency, or pests?White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?

Calcium deficiency?So, 2 out of 6 are showing this, it looks like a nutrient deficiency, Calcium I'd say.
It's only present in one leaf on each plant, in the bottom.
I've got here CalMag ready to apply, just wondering if you guys agree with me :D
Thank you, and keep it green :D
