dodo you sure you didn't mean the flowering cycle??? if you took them in veg, why would it take them a month to start vegetative growth? LOL

Clones should start their life under 24/7 and be brought down to 18/6 when they have roots, at least thats what i saw in jorge cervantes grow dvd and have read on here, probably under the diy bubble cloner thread. I took my clones when they were 2wks into 12/12 and it was also before i had a ph pen and my 2yr old ph strips that were inacurate led me to believe my ph was alright. 7.2 is not alright for clones. haha. Most likely why i had weird, one leaf, and 3leafer clones. A week or so after my ph was around 5.9-6.2 my last clone taken in flowering, started growing normal 5 leaf fan leaves. I took my clones off the bottom branches where there were little to no flowering going on. I'd say go for it, you're clones might flower early but big deal
