Gg#4 blimburn seeds

Plant growing well not very frosty . Might have to do with my ph pen breaking and not knowing it for a few weeks so plant showed signs of ph lockout I bought a new ph pen (a good one blue labs) could never get the plant to go back green so since week 4 she's been a bit light green looking despite cooking up a nitrogen heavy compost tea. Missed a week somewhere she is in week 7 of flower almost 8 weeks in.
