Is that not enough calcium?
BlueSugarLeafstarted grow question 7 months ago
How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Does look to be beginning of calcium issues forming.
BioBuzz does not recommend anything under 6.2PH for their feeding regime. I'd lower your feeds and keep up with the CaMg supplementation. When growing in soil I find its best to feed once a week and water the rest of the days, especially if your not getting any runoff with it. If you are getting a bit of runoff, then it might be time to get a bit more and prevent the salts from building up in the medium.

Good Luck!

Not pest or disease, but over fed with nitrogen and with a developing calcium deficiency.

I think you cam safely eliminate pests. It very well could be lacking in some of the trace elements you mentioned. Before changing anything I would take some runoff measurements to make sure your rootzone is in an acceptable range. You could be providing the right nutrients but it can't absorb them. If your runoff is good, consider a CalMag supplement.

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!

Healthy?Sie wachsen zur Zeit sehr schnell allerdings haben manche Blätter Flecken wie man sehen kann. Die ersten Wochen habe ich leider mit einem zu hohen Ph Wert gegossen (ca 8) dies habe ich jetzt aber angepasst und sie bekommen ihre 6,4.Vielleicht Nährstoffmangel? Bio Grow hinzufügen?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

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.

Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

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.

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…
