Calmag issues

Rookie_growsstarted grow question 3 years ago

Hey guys, I've noticed a few rust spots on my leafs, the plants are in week 3-4 of flower. I've checked and it is not rust mould it is definitely a Calmag Issue, should I up the dose or could it be locked out? Just thought I'd ask before I either flush or make a feed

You need to check the runoff from your planter after a plain watering. Check make sure your ph is in the proper range for the type of growing medium your using and for the stage your girls are in. Also check your runoff water for ec levels. To low is a deficiency, to high would be lockout. If your ph is out of range that is also lockout. Cheers

It’s a Calcium deficiency in middle flowering, in most of all cases it is curbed by an excessive amount of ammonium, potassium, magnesium and/or sodium in the root environment. The only way to know it’s to control the EC level of the soil by checking the drain.
