ok... I finally got the ph pen! my runoff is at 7.4! still too high, right? So how do I get it to balance out? Do I use ph'd water as suggested by Dorje? Also, I was right about the mg deficiency. The research I did also suggested a possible zinc deficiency so I used a weak blooming solution containing manganese, zinc, & iron & foliar fed every other day to the affected areas. The leaves on the new growth are looking very healthy now & the twisting & taco-ing is no longer an issue! Cool! I've decided to place the two plants that aren't fairing too well outside & hope they will thrive out there & keep the two that did very well inside to focus all the light on them. Hopefully I hid them well enough in my yard. They will get some good direct sunlight but not as much as I'd like. I think I will just start flowering the two indoors in a couple of weeks & start over from seed & chalk up a minor defeat on this grow. Will still get some buds so it won't be a total loss. Like I said before... that's why I experimented on some good seeds & not some great ones!
