Update Sunday...
This setup is almost too easy!!! I knew I said I wouldn't check the ph/ppm during the week, but I did to see the swings from day to day. I have been adding 1-2 gallons of non ph'd water each day to maintain rez levels. The ph would go up .1 for each gallon added, for instance I started with a ph of 5.8 and the next day after adding a gallon of water it was 5.9. The ppm's would go down anywhere from 20-50ppm adding that same gallon of water. So with a starting ppm of 1360 last Sunday, it was down to 1270 today. All within acceptable range of the Lucas formula, so all is well. Also, I initially said I wouldn't adjust ph/ppm during the week, but after adding back plain water the ph went up to 6.5 Thursday. So I added 25ml of ph down and it went back to 5.8. Knowing all of this I will probably check everything before lights out at 12AM Thursday morning and adjust if necessary.
Today I adjusted the ph/ppm to 5.7 and 1360 respectively. Temp inside the tent are in the mid 70's with 51% humidity lights on and 50's with 45% humidity lights off. I know the 20 degree difference is a big jump, but at this time I don't see any negative effects. I will address it later when the weather gets colder. Rez temps are even more steady with the canopy filling out and stay at 65 degrees with the lights on...not sure about lights off, but my guess is as low as 50 degrees.
Next week I will start the flowering cycle.
