Who does #2 work for?!

Day 50/14 ph 6.1 ec 2.14 temp 67F Day 51 ph 6.1 ec 2.24 temp 70F. Res change tomorrow or the following. Day 52 added 8 gal to res ph 6.0 ec 2.25 temp 70F. Changed over to Grow More PH down 30%. Twice the strength of GHE and nearly half the cost. A double win! Day 54 ph 6.1 ec 2.32 temp 68F, if EC raises again tomorrow, will add ph water to cut it Day 56 ph 5.9 ec 2.75 temp 68F, added 2 gal tap water to raise ph and cut ec. Plants have been drinking heavily lately. Raised the lights to near max. Plants still stretching and if they continue I will either have to dim my lights or rework the base of my flood table and plumb straight down thru the tent through platform and to the res. This will gain me about 8 more inches, but a lot of work. Res now ph 6.1 ec 2.36 Total cost of all nutrients to date $6.78
