THERMICDESERT11started grow question 5y ago

Growing organically with happy frog mixed with a super soil concentrate. I water them with spring bottle water, ph at 6.Recharge every 10 days. Top dress 2-2-2 dry amendments and I top dress in week 4 of flower with the super soil concentrate. Why are my leaves having spots?

It’s a Calcium deficiency. Just make sure it isn’t curbed by an excessive amount of ammonium, potassium, magnesium and/or sodium in the root environment. You might to control the EC level of the soil by checking the drain.

Possibly a Cal or Mag deficiency.

In experience with happy frog soil I had to keep my water very close to 6.7. I did not mix with super soil. Any major ph fluctuations gave me nutrients lockout. Mainly calcium. In your first picture, it clearly shows signs of ph fluctuations. A diary would also help alot.

Possible P Deficiency?Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.

Deficiency?? Excess? Neither?Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.
