1 weird deficiency out of 14 plants??

Here is one of my plants that has been growing under 2 27watt CFL's in a 2.2'w/6't/3'd well ventilated space w/fan and a temp of 74F. I have had them on 24 hr light. they started in peat puck then transplanted to a high qaulity herb potting soil in 4 inch tall clear plastic cups with rocks for drainage athe the bottom. Water every time top soil is dry a inch down. No nutes yet This plant is 10 days old. before bottom leaves were taken off.



Bottom leaves clipped and photo taken right after, tips are dry and browning as you see has progressed.


Someone please help this one was the best one , thanks!

Help please?!?!

Well, for one thing roots don't like light they like it dark so the clear cup could be one problem, transplant into a dark container. Also whatever planter pot you use needs drainage holes at the bottom so water has a place to drain through, it may be drowning. Change these 2 things soon and i'm sure the baby will feel better.

Thanks Brasmith!!!! I was wondering about the light to roots thing in my other journal thread https://www.rollitup.org/general-marijuana-growing/79810-1st-cfl-grow-outdoor-1260m.html but it seems no one could answer my questions in that one. Feel free to check it out and give me any other hints you might have, Thanks Again!!!!

u could also use a bigger container

Ya, transplant time is fast approaching this one is at 11 days since poking out of the soil, I wasn't really expecting this fast growth.
