Why is the tip of my leaves burned? Happened on two out of three plants – Perlon Lightmix – After 10 days: 0.75ml Alga Grow

Dear Friend, I couldn't see the all growth as you don't have a diary but you are doing it all wrong. Sensi Bloom is for flowering plants and there is not enough nitrogen for the plants which she needs at this stage. The tip burn is the excess P and K accumulated in the plant. Flush your plants with PHed water and then start giving Grow nutrients in the next watering. Additionally, your plant will need to much moist, so put a plastik transparent dom on the plant. It will help her recovering faster. Hope this helps, Happy Growing, Y
