Calcium deficiency or Fungus? That is the question

I live in Florida and it has been raining hard everyday… about 2 weeks ago I noticed leaves were getting rust colored spots, then the leaves started to yellow and I pulled them off. After researching different leave problems, I feel like it looks like either a calcium and or magnesium deficiency or septoria. Any ideas on what the problem is and how to fix it?!? Thanks In advance!


The outdoor growers will recommend you fill out a support ticket, I’ll find one to fill out, mean while you got any pictures of the whole plant? I know it’s night here on the east.

Tickets always help. But this looks like more like a pest issue than a nutrient, except the tips… Definitely need a ticket

For ticket click “beginner”. It’s the top sticky.

Here is as much info I have!

Plant is- Durban Poison, bought from Ilovegrowingmarijuana.com
-Age of plant- germinated April 15, so more or less 14 weeks old.
-Method: Soil- organic fox farm “strawberry fields”
-Vessels: 5 gallon pots
-PH- I don’t know, but would like suggestions on how to measure PH.
-we use fox farm organic fertilizer, grow big and the one for root support, will switch to big bloom when it starts flowering.
-it has been raining a LOT. We haven’t been able to give nutrients every other watering because we are worried about over watering since it is getting so much rain already.
-it is also getting less sun because of the rain. In the beginning of the grow when it wasn’t raining everyday the plant got full sun and it’s feeding and water was regulated it was doing great! Now it’s growth seems stunted. That is all the info I have! Thanks In advance for your help and knowledge!!

That’s a pretty old girl. In your most recent pictures I don’t see anything abnormal honestly. Old fan leaves get eaten when the plant decides it’s done with them. If it was more abundant or affecting new growth I’d be worried more. Keep an eye on her and maybe invest in an apera pH meter. All that rain will have flushed her good so she’s definitely hungry.

Looks like it needs food to me. At this stage and that size they should be getting close to or more than 8 to 900ppm. If not more. A ph meter and ppm meter would do u wonders here. Meters can be got off amazon. Apera ph20 for a ph meter and u can just get away with the 10 or 12 dollar vivosun tds meter. Happy growing bud ill follow along for the ride.

What is a ppm meter? Thanks for your help!

It measures dissolved solids in water. These you can go cheap on just be sure you buy the scale you want to use. Since there are 3 different ones.

Roflmao once the ticket is made, the answers flow forth like a river :slight_smile:

@Budz with the info hook up. That would have been good to know buying first setup. 500 scale 650 scale and 700 scale.
I found this conversion chart for 500scale to 700 scale.
