Brown specks on leaves
ChopperMcOGstarted grow question 2 years ago
I've noticed small brown specks appearing on the lower leaves. Does anyone know what might be causing this? I'm struggling to keep heat down and humidity up due to the weather. Could this be the issue or something else?

Your ppm should be at the 400ppm 0.8ec to 450ppm 0.9ec at this stage in their growth. 5.8 ph through veg, check often and 6.2 and 6.3 for flowering time...Most autos you stop increasing their food when you reach 600 to 650 ppm. only give more if they really need it and keep your water as cool as you can...

low ph and to much food. use the light feed chart and cut the amount in half. ph range is 5.5-6.5 so with you having it at 5.5 it can go out of range to easily

Do you splash it when watering and leave the drops on the leaf under light?

Your ph in water grows stays at 5.8. Over feeding is your problem...Guaranteed

To add to what Roberts has said, you need to raise your PH to a minimum of 6.2 in DWC for calcium to be absorbed... you may be giving it all the calcium in the world but if the PH isn't right, it won't help.
Good luck!

Looks like calcium deficiency, and a spot where the leaf got wet and light was too strong.

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

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?

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?
