All in all everything is going well.i have some burnt tips but that's not to big a deal.im hitting them hard right now but still not going over 900 ppm .some people like to hit 1200 to 1500 but I think that's asking for trouble personally. After this next week I will hit them all with herculean harvest and fish shit and maybe one more dose of calmad plus.i might feed the samo one additional week because it say 9 to 10 weeks of flowering and my other 2 are 56 days.my humidity is pretty low.mid 30s now so I hope that doesn't effect my final weight.i hate winters.im going to buy a new humidifier in the next week or 2.i killed my last one .
