Getting the rust off

A quick note as I'm starting this journal at week 6, I'll note it's week 6 since germination, and that until week 4 I was in soil. At week 4 I transpoted from 750mL pots to 2L pots and in the process stripped as much soil as I could from the root ball. This was in part to a minor thrip infestation. Last night I finally got my EC meter, and realized just how bad my tap water was. I've been watering at 1600 EC (you can sea a few bad spots on some of the largest fan leaves). Fortunately I had some distilled water to dilute current mix, so I get 2x waters last night with 1350 EC. I'm getting lots of distilled tonight when I grab groceries for the week, in 4L containers. But as I'll soon be switching to 5 gallon grow bags, I should find a good source of 5 gallon RO or distilled water. I supercropped the stem around node 2-3 for 3 of the plants, and did a bit of LST to arrange things better. In a few days they'll need much more LST. One plant I cracked the stems of both sides of node 4 while trying the rearrangement, and thus the electrical tape. The 4th plant I'm attempting a mainline since these are seedlings. I might have cut it close when making the top. I lost some stipules, but don't think I harmed the growth spots. I left on some of the fan leaves that will likely later be trimmed, but only 4 growth zones are left. I'm thinking I'm 2-3 weeks from going to 12/12 - the main issue will be the mainline plant - this is taking a lot longer. I'm definitely interested to see the results.
