What is the issue?
Oozlestarted grow question 3 years ago
Hi everyone!
I did a reservoir change 4 days ago and started to notice spotting on my Brain Fog (Burnt Toast x Original OG).
PH 5.8-6.2 EC 1.2-1.3. (.4 EC of cal-mag). NPK ratio (1-1-2) Added .05 calmag today and raised PH to 6.2.
Maybe it wants more P too?
Thanks!

Hey friend , i dont know if you before where feeding with calmag because too much of either calcium or magnesium (not sure wich one ,need to check the chart)locks out phosporus , because she definitely needs more p .
Stay healthy 🤙✌️

Adding what I think fixed the problem for future reference.
Pretty sure it was just hungry. Raised EC to 1.4 and the issue seems to have slowed down or stopped. Canopy temps were a little high (79-82F), so I added a fan and reduced temp to 75-78f.
Not using cal-mag with my feed (remo) and setup would cause a shit ton more problems.... especially at week 4 of flower.
Thanks for the answers.

In my opinion, your ec is a little on the low side for this stage. 1.2 is for early flower. I would be running them 7 or 800 ppm and only adding cal/mg if you see they need it., unless your using RO water. Keep your water as cool as you can. Otherwise everything else looks ok. Cheers

I added mycorrhiza to the coco coir from a local store. It turned out that there is slow release fertilizers in it. Was not indicated on the packaging.Please Help!
First time after watering with 5.7pH 400ppm drainage water was 6.7pH and 800ppm. I flushed her to 400ppm.
Yesterday was the second watering (450ppm, 5.7pH) and drain was 700ppm 6.7pH. I flushed her to 460ppm (1.5l of water), but pH still 6.6

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?

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.
Je vous remercie 🙏🌱

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.
