Help with Teen Clones

I would start feeding those girls at 500 ppm 1.0 ec then next week up to 600 ppm 1.2ec. I would also build a scrog for them cuz once you start to bud they will fall over being so stretched now. Luck in your endeavour

Hi there.. if that's the first grow, then this is quite a jump into the deep water.. Can you please explain your question "what do they need" a bit better? Are you talking about nutrients, or what exactly do you want to know? If so then you're growing in rockwool, so they will require a nutrient solution from the very start. Preferably with RO water (at least dechlorinated water), and at that age i would guess around EC of around 0.7 mS or so. They do look quite stretchy to me, but that might be the way you got them, if you just moved them to bigger cubes. so yeah, please be a bit more specific on your question, so we can help you out. happy growing!
