They be stretching!! she has sprouted up alot this week! I am not seeing the normal vigorous growth that i have previously and honestly I think its the $50 cheapo ph tester i use, its not very accurate i dont think!!!! Sooooooo I finally bit the bullet and bought a $120 one that arrives tmr. This should help alot I think as I am seeing deficiency issues that I believe are related to the PH being off!!! by next week I will know how bad my tester was, this is something i wanted for a while but just didnt want to spend the 120 for a quality one, hope this helps alot!!!
