Do you buy your spring water Squid? That's a pretty high ppm for plain water. I don't think it's a big deal but my RO treated water that I buy I think comes in well below 50 ppm's.
Here's what I did for my girls as far as feeding so far and it's worked out beautifully for me so far.
At day 7 or 8 I hit them with about 275 PPM of bio roots and camag+. I fed that mix twice in a weeks time. No sign of burn so the next week I bumped it up to about 500 ppm with the same mix as before but I added some grow nutes in as well. Same results, plants ate it up. So the current week I'm up into the 700's as far as ppm's go and am now on a full grow nute schedule starting around day 21 with no signs up burn or deficiency. I like to hit my girls hard and fast with the nutes, as long as they can take it. If they show signs of stress from feeding obviously back off. The veg stage of an auto is like intensive care in my mind, they need lots of attention in their young life (not to much though
) to ensure quality growth and a nice healthy, strong plant. I guess what I mean is that I went into this grow with a plan/feeding schedule in mind and so far it's been working great. Bottom line is that the ppm meter is your friend, I use it to determine my feeding schedule the entire grow. IMO the sooner you hit them with nutes the better. Of course this all depends on what grow medium you're using and so forth but it works for me. Looking good buddy. How about some fresh pics?
