Pale yellow leaves, curling downward.

Well i cant figure this out, ive gone from seedling to veg growth in the same kind of soil (bayer potting soil, with some lava rock mixed in to promote drainage and aeration.). As of late my plants been getting yellower and yellower whilst remaining a healthy looking green around the venial areas. The leaves also droop down, kinda curling under and into a very loose semi-sphere. Initially i thought it was burn from the lights but ive tested the tempurature all over the growth area and it hovers between 73 and 76, so then i thought it was overwatering so i held back and didnt give her anything to drink for a day or two, after that i thought it was phosphorus deficiency caused by lock out but the ph test came back at around a 6.5, i need to run another run off test though. At this point im at a loss, im not sure whats causing the problem which more importantly means i dont know how to fix it. Any input would be greatly appreciate by myself and my baby girl, thanks!

Sounds to me (somewhat of a noob), like you've got a Nitrogen deficiency. Check it out I could be wrong.

It DOES sound like a ph issue to me.....but I don't grow in soil so here's a really good guide to try....pics always help btw.... Good luck.

yea the only thing that i worked on and fixed that felt a bit leary of was the pH, so i suppose ill have to go back and test it again in a day or so.

and if i can manage to get my camera happy enough to work ill take some pictures.

Bah i was too slow with the edit!

well after reading through that guide you linked me to (thanks by the way found it to be very informative) im fairly sure its overwatering, according to this guide the plant will take a few days longer then i have already given it to completely recover so i suppose ill wait a day or so more and see, if not suppose im headed to the hardware store to get a bit more advanced ph testing supplies and some bone meal (as i have what i'd need to bring the ph further down around the house already.)

thanks again mate!
