Sensi Amnesia HPS

The grow is stable since the light stress from last week,, trichomes appear on one plant. I use again both fertilizer this week because the plants still grow. I remove also the nodes on the bottom 1/3. This spare 400W light don't do so well. I apologize for the pictures quality, my old ballast is not very stable but I can't change now,, that will give more stress to the plants
