Space Brudda-- while you were out, I made a few threads for reference in Sticky's, including the Defc. Pic Depot and the Quickie Ref. for run-off testing which has this and several protocol improvements,... in the end, r-o testing is still a crude guess!Ham-- the lights are a bit close, but T5's won't really light burn like HID/LED does,.. but the proximity heat is more of an issue,.. and seedlings don't want the light intensity that older plants do, for the first week or so,...

dude, this is a whole lecture series! You need a pH meter for testing liquids, and for in-pot testing, I recommend the Accurate 8 soil pH probe,... A TDS or EC meter is handy, not always needed, but provides vital info about your water (pH and hardness) and nute solutions if needed,... you may or may not need to adjust the water depending on it's pH and hardness, using pH up and down solutions,.. for adjusting soil, that's a can of worms I'm not going to open here and now, too much to go over,... if you mind your pH inputs on water and nute solutions, adjusting them before adding in, it goes a long way to avoiding having to fix soil pH in-pot,...
