pH of 6.0 will make your plants ugly I had a similar situation, my water (distilled+CalMg) was a pH of 6.0 and was causing my seedlings to ugly out quite a bit, apparantly below pH 6.5 the root system can't absorb the nutrients needed (whatever is in the soil) (here's a linky http://boards.cannabis.com/grow-faqs...u-can-use.html ). If I understand correctly, this can cause (at least in my case) salt buildup,general plant uglyness, and slow growth. I remedied this problem with some earth juice ph up. I used a seperate container to make a small amount of pH buffer (water and pH up), then added that sparingly to the water for the girls (use very small amounts as a little bit goes a loooooooooong way) and a good flush of the ugly plant.

Check the pH of the runoff, for me the only plant that had a runoff pH of below 6.6 was the ugly poor performer, so a flush was in order with some pH balanced water and this seems to have taken care of the issue.


EDIT: I checked C-I-L's website and they say the seedling starter mix is soil, perlite, and peat moss.
sensilights Reviewed by sensilights on . how do you guys do it?? how do you folks get your plants up to 4th set of adult leaves in seedling soil? (example is stinkys donkeydick grow log) Do you really use no nutes? I ask because my seedlings have looked the same for the last week, i have them in C-I-L seedling mix and all they are up to is thier first set of true leaves and the very beginning of thier second set (they are maybe 3 mm) and they have been looking exactly the same for a week now. I am watering with tap water which was left to sit for 24 hours Rating: 5
