Until you get a handle on plant nutrition, I can not help. I told you what they need, more N while you continue to give them products that don't supply enough N. Cannabis specific nutes suck because they use the wrong NPK ratios for plant health. Likewise, the Lucas formula sucks.
What kinda nutes do you recommend? Should i use supernatural aqua bloom with sensi cal mg? I have that available but afraid to try. how can i a ratio of 1-3-2 with general hydro?
 
I'm not trying to sound like a jerk but would I have better luck getting feedback on my question if I made a post of my own rather than commenting here? I'm not sure how the community feels about cross-posting.

What "nutes" have a high N profile, like a 33-0-0 or a 30-10-10? That's what you need to use to correct the excessive K and low N found in most if not all cannabis specific rocket fuels.

These are three auto-flowering Snowryder that are about a month old.
They're in soil. Nothing special, John Innes #2 from B&Q.
Lighting is a 400w HPS and a few CFLs that I have (200w 6000K, 120w 2700K) that I'm using for side lighting and figured couldn't hurt. They're on a 19/5 light cycle.
I've never given them nutrients.
The temperature is usually between 60-80F/15-25C.

I've been watering them a little bit most days. Been using the "lift the pot method" for seeing if they need water. Oh and like me, the plants just get tap water.

Yesterday I saw some of the bottom leaves on all three getting yellow and decided I was over-watering. Now today the yellowing appears worse.View attachment 2407576

On a slightly separate note, one of the plants has a yellow spot at the top of its growth that looks troubling.View attachment 2407575
Looks stunted. Plants have to have 16 essential elements. If you have abundant foliage and roots (which you don't) you don't need to worry about overwatering if using a good general potting soil.

Hey uncle Ben!

i think i have a little problem down here ... 2 of my plant have been stressed or something and the two other have some brownish spot on their leaves..
i didnt change anything in their growing tent for around a month so i dont think that could be the reason ...

I live in canada so it is possible that the temperature go down a bit in the night while there is no light but i dont think that is the problem.. But , it could be..

If you have any idea what it could be with the picture just tell me ... i am using 40% coco and 60% soil and i didnt feed any of them with any nutrients yet .. my water is okay ( well i changed nothing and it was okay for a month and a half so i guess it's still alright .. ) I am using CFL .. 2x25w , 5 x 100w ,

Here are the picture.

Suggest a good book on indoor plant culture.

Maybe if you learned some plant botany you'd get somewhere. You won't learn it in some hydro store or cannabis forum.

Find UAN from a feed store.

The crap you bought from a hydro store got you into this mess, you and the sales guys need to get you out.

What?! It is far from a waste of time: what uncle Ben suggests is correct, learn some basic plant botany before getting angry that a veteran grower hasn't got the time or patience to be answering questions that have been done to death. Keep it up unc.

I understand not wanting to answer the same basic questions over and over again but if that is the case then he could always stop responding. I'm not saying that his contributions to the forum are unhelpful but perhaps the time of this being a sticky is over.

You guys really need to listen to what Uncle Ben says, this is a voice of experience talking, a beacon of sense in a sea of ignorance. What he speaks about is correct about the over zealous use of "hocus pocus" nutrients that costs an arm & a leg and are then used to cause serious problems by overdosing the plant on one or more nutrients, (see UB's descriptions on antagonistic effect) creating deficiencies that would have probably never arose had the grower paid more attention to what the plant was actually telling them. It seems people are obsessed with over-priced witches brews like they are the cornerstone of every successful grow; they are not.

Great guide, I've been having some problems like this and I think that I need to work on my roots on the problem plants, the plants with weaker roots are the plants with the problems... thank you! Picked up some hygrozyme today for my DWC, hoping that helps!

Low night-time/lights off temps can cause a drooping of the leaves, I've suffered this myself. Bottom two seedlings look starved, but I don't know how that could be possible as the grow medium should have plenty of nutrients to take the plant through the first few weeks of veg. growth, and sometimes beyond, before needing a top-up of nutrients. Also, I notice you are not using vermiculite/perlite; these are invaluable (I'd say essential) for aeration & water/nutrient retention & help greatly with the formation of healthy, strong root systems, whilst also ensuring the soil/medium does not get too compacted. The grow mediums also look very dry, water thoroughly until you get run off to ensure adequate wetting of the medium all the way through, and try not to let it dry out between waters as this can cause more problems with salt build up in the medium. Something else worth noting is, as coco contains no nutrients & retains little if any, a big enough percentage in the mix might have made a substrate with very little nutrient worth. You say you haven't fed any of them yet, not even the larger plants in veg. growth?; that could be one of your problems right there. Water often & thoroughly, feed when she needs...
