Additional info: It’s just onset the past couple of days my other Mohan started to rust like craz so I did a calmag foliage spray and it seemed to like it…..so I figured I would try to get some great advice from this pretty dope community

Looks like a classic Mg issue to me. Epsom salts will work to fix that if it's a deficiency but since it's the lower leaves I'm leaning towards lockout.

10ml of tiger bloom is a tad high. I only used 5ml every other watering and never added cal/mag. has mg in it's bottle nutes so you shouldn't need it unless it's a hungry strain or your soil wasn't ammendmend with Dolomite lime.

I ran OF so it had Dolomite lime in it and appears promix bx does not so you may need some cal/mag. I'd just back off the tiger bloom, add a few ml/gal of cal-mag and see how it responds. Just make sure you check pH like recommended above. I use 6.5 for soil. I was usually feeding them tiger bloom by day 35. Hope that helps.

Is it really yeah I had no idea I had to amend my promix with dolomite lime. I checked the ph of the soil and it’s at 6.6 and the PPM was 89 so yeah I’m def gonna back off the nutes on that one……oh yeah this is the feeding schedule I found for autos
