mornin Smerkey .... awesome picture mate ...awesome plants ,keep this up & in 6 weeks you will have a shitload of bud !
The PH rising is ok mate ... it coz your still slightly underfeeding but thats good ,will keep her interested & ready for the slight overfeeding at PK week
carboload is nothing like cannazym bro ... one is enzymes & the other is carbs & sugars !. you can add carbo to help with bud production & to make the weed smell & taste sweeter ,but it wont eat the dead matter in the res ? You might be ok without it now ? .... 6 weeks in & no problems ,girls as healthy as yours , so you can drop the zym & probably have no issues at all ....or dutch masters "zone" is good ,something else like that if you want to be safe ... or order online maybe , I have been since I started growing & no probs:Sharing One:
