Yellowing and wilting of leaves

After sussing out your entire grow, and without knowing what you put in the soil to start with.. I'll take a guess that it was in need of feeding about 3 weeks sooner then you started. next time id be running very weak nutes to the plant from week 3 onwards. Also nitrosol isnt really suggested for cannabis plants as the PH is wrong or its nute balance is all wrong- I forget which- but if its the nute balance is all wrong then its likely missing enough cal mag or some other nute you needed. if its the PH then it may be making other nutes you do have in the soil un available to the plant. Honestly any cheap nutrient from a hydro store would do... just dont expect results like the guys on here who use the most expensive organic nutes and high quality pre bagged soils if you are only using nitrosol and a bloom booster.
