I Have Problem

[daglas]

Hallo my friends,i am a new grower,i have 5 shiva shanti about a month.My problem is that when i put them under the agrophilips lamp400wat in a distance 60centimetres from the lamp, the next day some leaves were yellow and some others were wilt and their color was dark green.When i put them under the lamp was about 20centimetrs tall and they had about 6 rows of separate leaves.Is this heat stress?Is there anything i can do to save them?Is it likely that the distance 60c.is to short or the lamp 400wat is to strong for a closet?Please help me.

pictures would be very helpful. could be heat stress but 60cm=2ft is farr enough. check with a thermometer @ plant top, shouldn't be higher then 85 deg F (30 deg C) could be lack of water or nutrient problem as well. Compare yours with pictures when you go to this page:http://greenmanspage.com/guides/plant_abuse.html b1
