Calcium, lock out?
CannaTropestarted grow question 3 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.

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.

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.

Deficiency or Pigment?I have strange brown spots appearing all over my top fan leaves at week 7 of Flower. I thought this could be genetic coloring starting to fill in, but now I think it's something more.

Bruising or nute problem?I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.
