Well I started them at 300 and they were baby baby seedlings....did great...went up to 400 after a week and they started looking sort of dark green. This was my very first hydro grow so I thought that was a pretty cool color (they WERE quite pretty bluish green) so I upped it to 500 the third week before I finally got a clue. I think I ended up keeping them at about 400 until they were about 5 weeks old. In blooming they were nute monsters!!

Mg def. ahhh! ok well i figured this would happen becuase it has before with other strains, i got some BB in week 3 of veg, i had plain well water at 300ppms with high calcium concentrate. I put some epsom salt in and it jumped my ppms to 500! so i got poland spring water and dumped that in the res, adjusted to 400ppms im at week 3 of veg so im hoping these ppms are ok but i can see now that the plants are curling at this tips and burning, the lower leaves are the worst. I would post pics but they wont help. Rating: 5
