Brown spotting?
Granddaddy_Terpstarted grow question 2 years ago
Hey everyone!
My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean?
I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

It's a calcium defeciency. Not much to worry about. You can add some cal mag once a week to your feed. Cannabis needs a good amount of calcium, magnesium and manganese to thrive (along side the important npk). These are crucial for nutrient uptake and become in higher demand under warmer conditions and led lights

Looks like a calcium deficiency. If your using RO water or Distilled water you want to be adding in a cal-mag supplement. They are micro nutrients so not much is needed and tap water usually has enough.

I get these occasionally and I believe it’s a magnesium or phosphorus thing.. haven’t figured out which one fixes it

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?

What is causing this Leaf discolouration overnight after a lot of tent work yesterdaySpent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants.
I did lower the plant (was way too high) so may beight burn - but it’s only on some plants
I did make two mixes of water/nutes

Day 4, after emerging. Is this coloration on the cotyledons okay?Humidity is 55 - 70, temp is around 20-24c, 50w full spec led
It's my first time, and i think i have been watering it too much
I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

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.

Brown Red Round Spots on 4-5 Fanleaves / fungus ?Hey folks, I have this issue with one of my ladies. There are small reddish-brown spots on 4-5 fan leaves, while the other plants don’t have anything. What could this be?
I think it’s a fungus, but I want to be sure and know exactly what it is before I start treating it.

Tache cuivrés sur feuille.Je me demande si les tâches cuivrées sur les feuilles de ma plante de cannabis et d'autres plantes sont dues à une carence en calcium ou en phosphore/potassium. Les feuilles affectées sont généralement les grandes feuilles, souvent nourricières. Voir agenda.
