Auto Grapefruit Haze

Going into this week she still looks a bit stressed, however since raising the light nothing has worsened. 26 Aug - I spotted the first couple of hairs, she seem to be getting ready to enter pre flower 01 Sept - I've been battling nutrient lockout for the last few days. I bought a ph meter instead of the test strips I was using. Water measured around 7.2 and a slurry with the soil measured around 4.8. I've upped the nutrients significantly (I'll update the mix above tomorrow) and I'm going to try and battle until the end. The roots are too far developed to transplant into another medium and she is getting ready to flower.
