Yellowing and Droop

[DarthVader]

Hey everybody just wanted to get some other peoples opinions on this but I've got some pretty extensive yellowing on my plants and one is drooping quite a bit. Based on the research I've done I'm guessing its a sulfur deficiency, but that's just my stab at it

The Three plants are: JediXDeathstar, Cindy 99, and Maui Waui. I'm currently in veg and have been for about 3 weeks. I've got em in 2 gallon smart-pots with some roots organic original soil with a ph of about 6-6.5. I've been watering about once a week with roots organic nutrient solution, more specifically the player pack, Buddha grow, extreme serene, ancient amber, etc. I've got a 400w MH with on open hood. They are in a 2.5x5 foot closet with fans blowing

Did you start your nutes at full strength? you may want to back off a little until they are used to it. I usually start at 25% strength and work my way up.
Also, i would recommend watering once the week with just water, no nutes. They look a little dry and once a week may be too little.

plants drain well? a little too well? doesn't look like ur soil retains much moisture, n f thats the case-- it ain't retaining much nutes 4 ya either... LOOKS like nute def-- N in particular
AMEND ur soil w/ organic materials that won't wash/drain out w/ every watering-- or put a pan under ur pots to utilize the runoff. YMMV... Hope this helped! Aloha!

I agree with your soil looking very dry.... you should be watering around every 3-4 days. Yellow leaves could also be a nitrogen issue as stated by LivenBurn. Are the leaves dry to the touch?

I use 2 gallon smart pots and I have to water every other day. I've waited for the third day once and they were too dry so I went back to every other day.
