They look sick - What do you think? - PICS

Hi guys, my plants are looking a little sick and I thought you guys might be able to help.
The seeds are Nirvanas Chrystal growing under a 600w MH.
water ph'd to 5.8-6.5 and nuted with Jacks Classic 20-20-20 every other watering.
What do you think could be wrong with them?

looks like over watering.

maybe a little yellowing of leaves

i agree because the leaves arent folding down becasue of heat from the 600w

looks cold? temps?

well i'll tell you right now your giving them to much nutes... and it's definately not to cold in there... maybe in the off time for the 600 mh... what's your temp in the dark ? what's your light reg... ? back off on the nutes.. watch your watering... not to much., not to little... and keep a very close monitor on your temps...

Im on 18/6 for light schedule, and 1/4 tsp of plant food every other watering.
So far since transplanting a couple weeks ago they have been watered twice, only about 3 times total with any nutes
They have been getting yellow from the bottom up even before I began giving them anything at all.
The temp range is between 70-85 or so with 67* being the coldest it has been in there so far.
I though nute burn started at the tips but this seems to be happening in the leaf margins as well.

Maybe the 20-20-20 Jacks Classic is too much for them anyway even at 1/2 strength?

Heres a small update, yesterday I "transplanted" the plants into soil with a lot more perlite in it.
I also bought some new nutes 30-10-10 so maybe that will take care of the N defeciency.

The ONLY thing wrong with your plants is they are suffering from Nitrogen deficiency, they are not overwatered and they are not cold(LOL).

yup over watering

reading waaaaay to much into this. u did the right thing by picking up some new fert but all you had to do was simply increase the dosage of the prior one. she is just hungry, thats all. doubt overwater or anything else. they look healthy, alive and ready to take off. u should think about adding some fine dolmite lime into the top layer of your soil to help buffer your ph-also will provide some extra Ca and Mg that she will need at end of veg and into flower. you can switch back to those original nutes at 2x the amount u were previously using 1-3 weeks of veg and than cut it down, add some molasses for P and K. maintain your watering schedule and start with those new nutes just like you had been doing before. give her 3 weeks of this, take your clones and flower her.
they look well taken care of and good heart strain
all IMHO of course

shit Wu, you beat me to it. Maybe one day I can learn how to state things more simply-dont know why I always have to elaborate so much. this thread is very LOL.

i agree woomiester
