The plants are about 3+ feet tall. I needed to add a little baking soda to the water after I added the moor bloom. The Ph of the regular water was acceptable ( I dont remember what it was exactly), once I added the moor bloom the Ph level dropped quite a bit but once I added a teaspoon of baking soda It was back to a fairly nuetral level! I was considering getting some FF "cha-ching" for the final stages here....Will that decrease the yellowing? Does the Cha-Ching have the micro nutrients that you mentioned? At week 5 of Flowering....what are my next steps before harvest? Any info will be used and appreciated! Thanks Rusty!
