Cheesy Moments

Seeing some deficiencies, mainly much lighter growth around the top - thought it was sulfur or mag so added epsom salts, then wondered if they were just generally hungry so gave them another feed with some PK 5-8 and orgatrex, and burnt them a bit. The lightening on upper growth may have even been light burn - I checked with a LUX meter and some spots were getting upwards of 110k Lux, so I backed the light off a bit. I think the soil PH may be too low, affecting the uptake of nutrients. I've been trying to avoid flushing as it's not recommended with biotabs, but if they get dramatically worse then I expect that's what I'll do. I think they only have 2-3 weeks left anyway, so it's tough to tell whether issues are just natural colour change and fading, or nutrient uptake issues. Despite all this they seem to be filling in nicely, and getting frostier by the day. Super sticky, super stinky!
