Gropassionstarted grow question 6 years ago
I need help identifying the deficiency on the lower leaves, looks like a combination of cal and mag ? Your opinions will be greatly appreciated. I was thinking of adding some calmag from the local grow store.

You do have several issues present on the leaves. First i noticed soil then saw 5.8 PH ? That is pretty low and could be causing lock out soil is generally 6-7 PH 6.5 being around the best but some sway is ok. You only want to be under 6 if using Coco. Imo fix the PH and add a low dose feeding. You shouldn't need bloom in veg micro and grow should be enough. Good luck.

That’s not cal/mag at all it’s phosphorus/potassium burn plants of that size shouldn’t be getting any nutes yet. The burn isn’t severe but it is definitely not a cal/mag issue

Yes it looks like a cal/mag related issue, but you also probably have a boron deficiency. Good luck with these beauties bro!

Imo it's a cal/mag for sure. If you don't have any on hand, you can use some Epsom salt or even a small amount of molasses (1/2 tsp./gal.).. Calimagic is what I use, and I haven't had an issue since using it.

Pretty sure it’s a Calcium, Magnesium or manganese issue.have you introduced any neutrients to your plant yet other than the ones in the soil and what soil did you use.

It does look like a Cal/Mag problem , but it can come from many different factors.

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?
