Leaf coloration

This is an early stage calcium deficiency. Add some Cal-Mag to your feed and she'll be fine.

Hi mate. Have a look at my diary our plants look the same, very tall with leaf damage the same, when I add cal mag she responds well. Good luck.

It's most likely nutrient burn. If you were to check your tds I'm sure your ppm would be way to high.
My advice. Lower the feed and check your tds before hand to make sure you're not over doing it. You want it to be at like 400-500 ppm right now in bloom. The most you want to push her is 550 maybe 600.
Hope this helps

I also thought immediately of soccer like @Growstick... but normally this type of deficiency focuses in the center of the leaf and rarely affects the leaf veins. Still, it's a possibility I won't rule out... the other possibility is Septoria, which is a fungus that causes spots like those... I'll leave you a link to compare the symptoms and check if it could be the culprit... https://www.royalqueenseeds.com/us/blog-leaf-septoria-yellow-leaf-spot-on-cannabis-plants-n678?_gl=1*duvcaj*_ga*Mzc5OTUyNzIwLjE2Njc4MzMwNjU.*_ga_MFLBPT8N0L*MTY3OTUwOTM5NC4xMy4xLjE2Nzk1MDk4NjIuMC4wLjA.

Recurring Cal Mag issuesI’m already at the maximum recommended cal mag dose of 1ml/litre (with nutes at 1000ppm or E.C. 2.0) and I’m still facing issues.
It went away for a few days, but it’s now back.
Should increase the cal mag dose and cut back on the macro nutes to maintain 1000ppm?

Hello GD friends. My little Diesel Automatic is showing some odd mosaic'esque coloring on the baby leaves. I'm inclined to just let it go for now and see what happens. But if there are any suggestions on helping her out, please let me know! Thanks!Week 3

Discoloration 3 weeks into floweringDay 51 of my grow I'm starting to see some discoloration on otherwise healthy plant and I'm getting concerned. Most of the leaves of the plant are near the top. I cut back on my nutes on this last reservoir but the discoloring is still there. Any thoughts on what might be wrong?

What went on here??This is an Orange Sherbet I grew in Happy Frog with the FloraGrow series. I harvested early because I thought the plant was dying, and couldnt seem to stop it by flushing. Does this look normal for a plant being flushed out? Should I have waited?

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Spots on yellowing leavesBrown spots on dying yellow leaves. This has happened on most of my plants after budding so thinking it may be a soil problem. My guess is boron, manganese or phosphorus as the stems on some plants are red.
It starts low and eventually ends affecting buds too so I chop.
