Leafs are shriveling up

I got a problem with a coupple of my plants, a coupple of the leafs are starting to shrivel up, but just the bottem ones. Not the two little sun leafs that first come poppen out of the plant but the other 2 pointed leafs. and a coupple of my other plants the leafs are small and scrawnie. could u help me out?? No camra for pics.

Are you talking about the fan leaves?

yea, could it be that im not giveing them enough light, im right now given them 15/9.

or i ment 14/10

What kind of light are they under? How big are they? Have you been giving them nutes? Whats your ph? Soil, water? You should prolly be at 18/6 on your light cycle.

i'm having the same problem with my plants. the leaves arent changing colors or drying out. they are just curling up and its only the two first fan leaves. im trying to get a camera so i can show pics

i think i figured out the problem, i tested some fertilizer i bought on that plant and realized that it was the problem. so i tosed the fert and plant cuz its gona die, the fert was to acidic im guessing and killed some roots, never buy ross root fertilzer for acidic loving plants, lol im a dumbass

And wut do u mean buy am i using nuts?

LOL....OMG he really thought someone asked if he was using nuts. This person needs to read the newbie posts. Answer the questions you were asked they were very important.

Tere under a 150w grow light, my biggest plant is about a 1' 1/2", im giving them jacks allpurpous 20-20-20, ph is 7.2, giving them reguler potting soil with normal water (except for the jacks 20-20-20) water souilbel

Get an organic fert like fox farms, use at 1/4 strength. lower your ph. 6.3-7.0

i read that nuts thing wrong, it sayed nutes

and i got jacks classic all pourpous 20-20-20 plant food.
