Well , last week i flushed the pots because it might be a build up from salts inside the pots that blocked some nutrient. I flushed every pot with 10 liters of 5.8 PH water. And i ran out of my advance nutient Coco A and B so i changed them to Canna Coco A&B that i still had around and are also very good nutrient. So let's see if my plant will be ok . Plant 1 looks good but on plant 2 i have some discolored older leaves but that's why i flushed the plants on advice because it could be a nutient block . So let's wait and see how they will look next week. Tomorrow i think i will be doing some small defoliation to get rid of some leaves to get more light to the bottom.
