6th week critcal purple second time around

Let me start out by saying how late I am on your journal. I'll do a quick sketch of what's going on.With this second round of critical purple I went out and purchased a 5 by 5 grow tent along with a new 5 by 5 light. All three of my seeds germinated and sprouted from dirt at 6 weeks as of 05/06/22. Today I have noticed the flowering Beginnings with the white pistols coming out. They seem to be really thirsty I'm feeding daily.As of tomorrow I will be starting them on tiger bloom along with the big bloom. I have been giving 5 ml of fish shit per gallon.My pH range is between 6.4 to 6.5.I am keeping the lights 19 to 20 inches from top of canopy of plants. As of today I noticed some rust stains on one of the leaves so I started treating with cal-mag, more update on that in next notes,,, But as of today they seem to be healthy and thriving I'm going to continue everything as normal.
