ILGM White Widow Autoflower (2nd Grow)

Happy Easter Everyone! Time for an update During week 10 NEW LIGHT installed!! ViparSpectra XS2000. So excited! I think the plants are a little shocked from the change in light but hopefully they recover just fine. This week 3 of the plants definitely started showing some issues I have never had before. I started noticing rust spots on the upper top leaves of the plants which I believe was the consequence of the following... A.Nutrient lockout B. Soil PH too low from over fertilization C. Soil PH being too low due to the peat moss in the growing medium. I have purchased dolomite lime as an organic alternative to properly balance soil PH for my next grow. I did do a light flush with PHd water at 6.5. Plan for week 11 Going to be adding some Calcium to the soil during next watering to see if that helps new growth on the plants (Tuesday) At this point I will be just keeping an eye on more rust spots forming on the leaves. I have backed off on adding more P & PK at this time because I think I over fertilized last time. I am learning a lot still with every week of this grow. I know now how to dial in the nutrients and better amending soil first. Since my soil has peat moss I think that had a lot to do with the acidity as it breaks down. Really hoping these girls continue to finish out okay! Thinking that they will take the full 14/15 weeks at this point.
