sick plant

Plant seems to be drying, yellowing in spots leaves curling under. Growing in soilless potting mixture for about 6-8 weeks and I have not added any nutes yet. The other three plants still look ok but are starting to show some of the same signs. Growing under 100W HPS and fluorescent tubes. I watered a couple of days ago and I always let the soil dry out a little before watering again. Temps are 74F-79F humidity is 38-41. My cameras not too hot, I hope you can tell something from these photos.

have you checked your ph levels,, make sure there is enough air movement,,hope all goes well.............

Air movement is good but I haven't checked the ph, still looking for a tester.

My PH was my biggest problem,,,,, I didnt realize how Important to check and stabalize,, but it is,,,, needs to be between 6-7,, prefferably 6.3 to 6.5 in soil........

Could this be some kind of deficiency or is it probably a ph problem?

I would say yes it could be,,, safer to fix PH levels first,,,, When growing you are going to have to overcome lots of problems,, so, I would think eventually you are going to need all the right stuff,,, I tryed shortcuts and cheaper methods but they just prolong the problem,,, good luck.........

If you have not fed them and they are 6-8 weeks old, perhaps thay have eaten up the food that is premixed into your potting mix. With that in mind give them some food and make sure you use the correct NPK ratios for vegetation stage of growth.

Your problem looks like mostly nute defiencies.

If you can get foxfarm soil,, get it,,it takes you almost all the way through your grow without problems... great stuff...but it is time for nutes.......

Thanks for the replies, I'll keep at it.

This is my first indoor grow and first grow at all in twenty years (just rediscovered the joys of smoking) starting with just four plants.

nice,,, even number,,, gotta love,,, hey,,, did ya ever grow 4 plants,,,,,, on weeeeed........lololol.....................

Thanks, I would have started out full or half but I will go with 1/4. Is 15-5-5 good for veg?

you might want to make a watering schedule,, most newbies wind up watering too much,, Im speaking from experience...........

Started them on 1/4 nutes, I think they are already looking better
