Nutrient lockout

So I am new to growing and I have a problem. I am growing six hydro lowryder 2s. I am about three weeks in and my plants are showing the lower leaves spotting rust and curling down. I just changed the water and nutrient mix with less nutrients than before. I had some white on my grow medium but not on the plants (Salt build up maybe). I should have some pic soon just wondering how long I should wait and see if that fixes it?

Probably a good idea to just flush it for a couple of days with ph'd water if you are worried about it.

Then start up again with light nutes

So im running the nutes directly to the rockwool the plants are in with a pump, should i just run phed water for a day or so? I am using distelled water that has a ph right at 6.25 and my nutes are ph balenced so I should not have a ph prob right? Every time I check the ph its perfect.

I would change out the water and keep using the same distilled but lay off the nutes for 2 days.

And I probably would not feed them str8 onto the rockwool, can't you just run it through your resevoir?

It could be a ph problem, and/ or a combination nitrogen problem. How dar are the leaves and are you also foliar feeding?

Sorry, how DARK are the leaves?

Well the smaller 2 of the six are pretty dark but the big ones with most of the rust spots are normal just burn spots. so to me thats overfeeding right? thats why yesterday i put new water and nutes in with about 3/4 less than before. should I use alot less because they are lowryders?

Could be, I have never grown any lowryders so I am not the person to ask. But usually the rust spots are due to a problem with the nitrogen.

I would think that you could use a flowering nute all the way through on a dwarf plant. I guess they don't stay in veg too long and in turn don't need as much N as standard plants.

What nutrients are you using by the way?

A ph'd balenced pack from stelth hydro. was using a grow of 10-5-14 but only 1/4 the bag for the first two weeks then put in another 1/4. After I flushed it I put in a 1/4 bag of Bloom that is 5-15-14. and always the same amount of their micro bag. not sure whats in it.

Here is some pix of what I mean.

Now I find this if you look at the left two leaves it looks like they have been eaten. Someone PLEASE HELP ME MY PLANTS ARE GOING TO DIE!!

So I started to folie water them no nutes. Found two bugs and killed them the day after they did there deed. They look sad and drooping a little should I run water only for a day or so?? then add a light nute (about half what was in there before)?? The new pix are DAY 28 They look a little short to me they are Lowryder 2 but still. The one in the front middle is a female for sure and the one on the front right is a male for sure, I will be pulling him in about two days. ANYONE with help please do so. Will running water only for two days hurt them or fix the drooping leaves??
