So I transplanted some clones into promix. I gave them one feeding at 600 ppm of house and garden nutrients. I noticed the color started to change to the green/yellow and now the plants look sick. I also noticed the leaves becoming smaller and folding up. The plans are under thousand Watt metal halide and getting 18 hours of light. The water and food is PhD at 6.3 and the temps stay between 70 and 78°. Can someone please tell me what I plans keep doing this ????
Odd color taking over plant, help !

Needs nitrogen. If your giving it nitrogen, then rinse the soil and wait to fert again for a few days

When leaves curl down like that it can also signify too much nitro or too much water or combo thereof.
I would foliar feed first to test low nitro theory.
That way no danger of overfertilization.
Plant should respond within a day.
If not something in the soil is preventing the plant from uptaking npk nutrients that are obviously locked up in there.
Also Ph meter could be off and you're too acidic at 6.
Just a thought.
I'm new at this, too, but I'm a veteran at mistakes.

I don't think it's nitrogen. It's got plenty in the soil and it's not like it's working from the bottom up. It's all over new growth making leaves small and skinny and even folding up.
I did give the plant calMag and foilr feed with magic green.
The meter is brand new, it's a nice blue lab. I did foilr feed with magic green but again I dont think it's a N problem.

Over nutes?... rinse soil and use only PH adjusted water for a week
I feed them twice at 600 ppm and no burning.
I can't figure out the small skinny new growth...

Come on! 6.3 PH won't wont do that Sticky. You know better than that.
Did you just water the plants, or has the plants been sitting in the moist soil for a few days? From what I can see looks like it is under/over watered depends on if you just watered them or it has been sitting in that soil wet that long. Needs slightly more N and add a bit of Mg. Other wise they look fine to me. Few tweaks is all it needs.
Edit: I am leaning towards adding some Mg or epsom salt

Looks like the yellowing started from the back of the leaves,if so it's sulfur deficiency,and 1-2 teaspoons of epsom salt per gallon should fix it.

yea well i was just say it looks like a ph problem i didnt know his ph was 6.3

he said his water is phed at 6.3 this doesnt mean his soil ph isnt to low there is more then 1 thing in that pic that is makeing me think low ph. just saying thats what my plants look like when the ph gets to low or when i give them to much magniesuim it locks out maginese make it look like that some times

Your PM is full so I could not respond. I agree with you that the water PH doesn't mean that the soil PH isn't low. Yes, there seems to be more than 1 problem going on but its not that bad I think. I have done a grow without PHing at all while my tap water as a PH of 8 on plain water days and when I feed the nutes bring the PH to around 6.2 to 6.8 and I actually yielded more and better quality stuff at the time. Just my experiences here. Now, I wouldn't say stop PHing your water as I still do ph.

Perhaps, I've seen a few trying to use only distilled water.
Sounds good, but also other possible issues. I may as well be told I should know better also.
Is he new or a vet with a never before encountered problem?
Does not say which promix, some are pre nuted. New clones, how well developed are the roots? Freshly transplanted, do they have sufficient soil contact? Freshly transplanted into pre nuted soil plus being fed? Freshly transplanted, moist soil or drenched?
Just a possibility I do not know anything about him so I can ask does he know when a clone has sufficient roots for planting?
Yellowing leaves on cuttings
When unrooted clones start to yellow it means they are either not touching the rooting medium good enough, to much co2. The vast majority of the time, an unrooted cutting will begin to yellow some of it's leaves, starting with it's largest oldest leaves, because it is too close to the lights and it needs to be moved farther away. Some yellowing is normal just as the cutting begins rooting and can be a sign of the cutting using it's oldest leaves as a food source while it is forming new roots. Plain tap water that is ph adjusted is just fine until the clones have rooted. Giving any ferts will kill them untill they have been rooted.

When you feed someone enough possibilities they should be able to solve the problem by looking back at what they have done to get where they are.
