My plant is starting to grow her 4th node, is this a good time to nute? Also, what nutes would you recommend for vegging (something that will not change PH levels)?
I go with fox farms line for nutes. So its about 2 to 3 weeks old? Thats a good time to start, just be careful with that young of a plant. Use a 1/4 strength at every other watering slowly working your way up, and make sure to flush every 2 weeks. Any nutes used long enough will cause a salt build up and lock out certain nutes, there isn't one that wouldn't do that as far as Im aware.
ska rocks ...... anyway, mine are at about the same stage and i gave them a 1/3 dose of nutes, they look even better now so i would say go for it, although im no expert
