Bruce Fast Fem - 3rd grw

July 3 - started to weave thru scrog. noticing the space between nodes is very tight. currently at 34k lux. also there is noticable yellowing starting from the ends inwards on Bruce. started 2 days ago and is increasing. setup Inkbird humidity and temperature wifi monitors. these are great! Im just using them to view numbers and not adding a humidifier/AC ect. July 5 - went to local hydro store for advice. said yellowing possible due to dropoff in soil pH, so raise ph to 7+ for 3 or so waterings. slight tip burn from over nute but nothing substantial. some purple stems as well. July 6 - added 4 ml/l miicro, next is Tues July 20th
