Rusty brown spots

Just recently these brown spots have appeared. Mostly on the top fan leaves. The bottom leaves don’t have any spots but I’ve been losing a little bit of the leaves to a nitrogen deficiency which I read was normal. I’ve been growing this bud in the same happy frog soil from veg to flower. There in day 36 of flower now The humidity for flower has sat right around 45%. I’ve been watering them every other day and every other water feeding them half the recommended doses from general hydronponics. I recently realized my water PH was a bit high at 7.2 so I’ve brought it down to 6.5- 6.2. The tent itself has been fluctuating between 63 to 85 degrees. any ideas what it could be?

Looks like a Calcium deficiency and you can try adding some Cal-mg. If you're using GH floratrio, add the Ca-Mg first, before the Micro and Bloom. Nice looking garden!

That’s what I was thinking! Thanks man I appreciate it

Now would you suggest feeding it just calmag a few times or adding some into the bloom cycle for general hydroponics? Also do you think every other day of watering is enough? Appreciate the help

Thanks for this post. I started having the same thing about a week ago.

I've been in coco/perlite for a few grows so I use it from seedling to chop. In soil, you can try adding cal mag to your regular bloom feed but back off the floragrow a little because most cal-mg products already have N. As far as watering every other day, that depends on your containers, drainage and how much the plants are drinking. Those plants look excellent so don't "fix" them too much

Word up. I’ll probably hit them with just cal mag to fix the problem for a feed and then introduce it into the bloom feed

For a great calcium source look at Herculean Harvest. It has a low pH and should be adjusted. (Preferably with calcite or Olympus Up)
It's basically liquid bone meal.
