Calcium, lock out?
CannaTropestarted grow question 4 years ago
Hello, it looks like calcium, P, or K issues. Maybe pH lock out. I flushed last week and followed with nutes. Likely last nutes this week followed by a week or two of flushing before harvest. Please look at leaves and let me know what I should do as I end off this plant.

The spots look like cal mag problem. Could have been caused from a bit ago. Your leaves look like they have a nitrogen build up, dark and shiny leaves. You may have been running slightly to high a level of N when you was in flower and this may have caused the other problem. I would flush and just drop the grow. Use half micro to bloom nutrient. So if 1ml micro 2ml bloom. I would also say your a while away from starting your final flush.

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…

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

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.

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.

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?

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.

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.

Runoffs are significantly below inputs-Do I have a problem?Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?
