(Sensi seeds) Silver haze project

Hey guys welcome back in week 18, week 2 flowering of the Sensi Seeds Northern Lights #5 X Haze! She is still stretching pretty hard but mostly the shoots, she starts to get bushy again so i think i need to trim a tiny bit next week. Unfortunately my C4 of the Mils nutrient line has gone bad :( so needed to find a way to give the right nutrients with the things i got at home so i improvised a bit. But i think i will finish her with a Plagron scheme and possibly use some Bio green aditives, let me know what you guys would do! Further more i was thinking about oxygen flow in the roots, and it reminded me that i had a aquarium air pump left, so i putted it underneath my pot in to the soil ( i dont know if it acutely works, but i red about people doing this and harvested 20% more) does any of you guys have experience using this kind off method and maby on how to improve this method? UPDATE: I've had contact with Mills nutrients and they were surprised to hear what i had to say because it was the first time they heard of a bottle of them had gone bad, they were cool enough to send me a new bottle of C4, as soon as i get the bottle ill switch back to the scheme of Mills again! Thanks Mills for being so awesome! Well thats it for now see you all next week!
