Im using Tiger Bloom in flower, yes. I didnt get both Big Bloom and Tiger Bloom. I figured one veg and one bloom nute would be sufficient. My plants are doing decent, but I noticed some brown spots forming on the tips of the leaves. Some of the lower leaves are still yellow on two of the plants. But I noticed Grow Big does not have Calcium. Will I have to give my plants a little Cal Mag soon because of this? I noticed that calcium is vital for growth and I think I have seen a decrease in the rate of growth. Also, one of my plants is drooping regularly. Seemed to perk up after I watered it, and then later in the day the leaves were drooping again. Any ideas? Pics coming in a few.
