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

anche io come @Growstick ho pensato subito al calcio...
ma normalmente questo tipo di carenza si focalizza al centro della foglia
e raramente tocca le nervature della foglia
e comunque è una possibilita' che non tolgo..
l'altra possibilita è la Septoriosi che è un fungo che fa macchie come quelle..
ti lascio un link per confrontare i sintomi e controllare se puo' essere lei la colpevole... https://www.royalqueenseeds.com/us/blog-leaf-septoria-yellow-leaf-spot-on-cannabis-plants-n678?_gl=1*duvcaj*_ga*Mzc5OTUyNzIwLjE2Njc4MzMwNjU.*_ga_MFLBPT8N0L*MTY3OTUwOTM5NC4xMy4xLjE2Nzk1MDk4NjIuMC4wLjA.

Root rot or pH imbalance?This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Interveinal chlorosis and dead spots on leaves, deficiency?This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

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.

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!
