my clones tips turning ellow pale

i had my clones 5 in cups of water 4 in soil and now thwy produced roots and i removed them from my aqvarium and placed them under flouresents and theyr tips the youngest leaves started to turn ellow i was expecting something like that to happen to the tips of the older leaves,can someone tell me what could be the couse of this

We moved our clones into our veg after 2 weeks of them vegging elsewhere. They got to looking really bad and most them had turned half yellow but after day 3 of them on they're nutes they're back and full swing. Hows your Ph? And how many times you water them?

whats the ph of the water used?

destiled water is what im using

do you check you ppm or your ph? You don't use any nutes? It can be a whole lot of things but i would guess maybe your ph is either too high or low and your plants might not be taking nutes cause of it.

could it be the lighting conditions are different to what the plant is used too

my plant did this when i cloned it cus used dif lights i went back to the original lights and it ended up about 6 foot tall lol

i just got me a ph meter and im learning to use it ,for now im using destiled water ,can u tell me after a see roots sticking down from my drainage holes on the medium is it time to use nutes becouse for now a didnt use any nutes 3 weeks pased since first cut em and placed them in water and about a week since i planted them in soil
