Plants seem to be dieing, please help

Hello, I've got 5 Purple Kush plants in rockwool that are put onto the big hugos
And 1 little guy (aurora indica) I got from a seed (feminized)

I've got all six under a 1000W Hortilux set on super lumens via digital lumatek ballast, and I been vegging them from clones for about a week now.

About 5 days ago I noticed they are drooping, and about 3-4 days ago I started noticing yellowings, now they have a bit of the yellowing on the top areas, and one of the plants leaves has curled up and seems like it "burned" or died somehow

I have a 3gallon bucket I fill with arrowhead water, fix ph to 5.5-6.0ish

Currently giving it these feeds:
DNF A Grow [base] 16.5 ML
DNF B Grow [base] 16.5 ML
Roots Excelurator 3.3 ML
Drip Clean 1.2 ML
I also add 3ML of SuperThrive & 15ML of Botonicare Cal-Mag to ensure they have all the iron/calcium they need

I have been following the house & garden nutrient formula using their Aqua Flakes, however since i had previously purchased DNF I decided to use that as the base and not bother with the house & garden brand for this harvest

Basically leaves are yellowing lightly, definitely drooping, all of them seem to be crumbling downwards a little bit and just look unhealty now

I'm lost and not sure what to do, I hand feed them once a day usually around 11AM and they are on 18/6 and sleep from 11PM to 5AM

If anyone knows what im doing wrong, or if I should maybe go buy the Aqua Flakes base nutriants and use that instead of the DNF maybe thats why (cause all the chems I bought to follow their online recipe is their brand anyway) only thing I use thats not by House & Garden is the Super Thrive, Cal-Mag & base nutriants [by DNF]

I also should add that I've currently changed the setting on the ballast to produce 750W instead of SuperLumens (1000W+) thought maybe im burning them

Help please, pictures are attached
Thanks

Nobody knows? : (

Looks way too dry, clones love moisture and get water through thier leaves, are they covered with any kind of "dome"?
Usually strait water from a mist sprayer of some sort, no nutes, twice a day. spray inside of dome. otherwise you would need 90 to 100% humidity levels in your space. leave dome off for a few min. for air renewal.
keep out of direct light for 4-5 days and then far from the light after that. about 2-3 weeks they should be rooting again, and then remove dome.
Is your medium saturated at all times? it should be
hope this helps

So you're saying I should be spraying them with some general water (no nutes, no regulated PH) just to get them wet at the top?
I thought this is over-watering issue
Are you sure I am supposed to take em out of the light?

Yea first off how old are the plants? And clones I'm assuming? Rooted hopefully...

That rockwool looks about as dry as the Moab! Get them some water man! Clones at such an early stage NEED moisture! And secondly that 1000W light is just way way overkill at the stage they're at. Maybe even hurting. The plants are still small and do not by any means need 1000W of light. A little 250W would be fine right now for a couple weeks.

I think what's happening is they're drying out WAY to fast because of that godamn massive light you have on them right now! hahaha, how far from the plants is it? Move that bitch further away or get a smaller light for the time being, cuz they just can't handel the heat right now, it's drying out that rockwool faster than SHIT I guarentee you that! And that's where the "wavy" and dryness on the leaves is coming from. To much heat up above, to close, and drying out the rockwool.

I grow in soil so I'm not completely for sure about rockwool, but I do know 1000W is a shit tone of light for 5 itty bitty plants, and it would dry out my soil fast... Which holds moisture 50X better than rockwool does... And since I grow in soil, I can't say alot about your nutes. It sounds like your feeding them to much though! They're still small man, let them grow a little before you feed them. Like a baby breast feeding, they need just milk for a while cuz they'r TINY! And when they start to get bigger you start to feed them solids. Same sorta thing with plants, when they're TINY you feed them only water, like a baby get's only milk, and when they start to get bigger you start giving them nutes... Well, with soil anyways... Like I said, I grow soil. Hope this helps some tho.

less watts, more water/light nutes once they begin to recover, the rocwool shoud be well saturated at all times (i use it for every grow)

Ok I have used my digital ballast to reduce the wattage down to 600 (It has 600w, 750w, 1000w & 1000wsuper lumens) as available settings. [1000W Hortilux Super HPS lightbulb]

I water once a day usually, and the time I took these pics the rockwool (the tiny one they are stemmed in i mean, not the hugo big one they sitting in) was moist, I thought I was over-watering and that that was my issue. Maybe I was wrong?

I will add another gallon on top of my 3gallon feedbucket I have added all the chemicals to, this should reduce the strength of the nutrients, but I am following House & Gardens nutrient list, so I figured I was not doing anything wrong...
Please check out my nuterient list, i have added it by picture to this post

My light is 3 feet away from the plants, and is at 600W atm

definitely don't need 1000w. i have 10 plants under a 400w hps and they're growing 1/2"-1" a day. i have plenty ventilation though, what is your ventilation system like? i keep mine 6" away from the tops of the plants following the studies shown in the charts below. hope this helps cuz it was a nice find for me =]

"Raising the lights deafeats the purpose of HID lighting." SeeMoreBuds. if you don't have the proper ventilation, DEFINITELY use cfl's. SeeMoreBuds' "Marijuana
for less Grow 8 oz. of bud for less than $100" says to put them between 2"-5" away from the tops and use fans to blow across the tops. 45w cfls are recommended as they put out about 150w equivalent and you can buy them at your local hardware store for around $10. if you have 2 or 3 of them and put them at varying angles you can grow some fairly large plants with killer buds. myself, i'm rooting cuttings and vegging some seedlings with cfl's and i have a nice ventilation system that only cost me about $200 for the inline fan and ducting and a little creative work by my dad and now i have my flowering plants about 6" from my 400w hps and they're growing 1/2"-1" a day. also, doesn't look like any nutrient problem i've seen but to be 100% sure check out this link and maybe you can make a connection better than i would =] http://www.marijuana-seeds.net/Thanks-ThankYou.htm weird link name lol but it's actually a sort of plant problem solver with excellent pictures and in-depth detail.
oh and it just hit me that maybe you are overfeeding and getting symptoms of nutrient lockout. the cannabis grow bible by ahmed says a good rule of thumb for feeding is every fortnight (once every two weeks).

Roots need oxygen too! You said your watering EVERY DAY? Unless it's super rockwool, I would give it at least a day between waterings...I use dirt so...Maybe I'm wrong...but MAYBE NOT!

Wait until you press a napkin on the top and barely get moisture...

They seem as if the proper nutrients are not getting in. Due to the yellow it seems like Nitrogen is being locked out of the plant. Something as simple as an imbalance in PH can hinder plants from absorbing all the nutrient they need. This would be my first to check. Hope you get it all worked out!

First and foremost, I want to apologize for not reading everything before posting but I am going to side with the first few posts. They look super dry and instead of using your big light on them go and buy a 24" aquarium light and place that over them at about 8-12". Place a dome of some sort and mist them 2 times a day with 5.5 ph water and make sure the cubes stay MOIST and NOT WET and definitely NOT DRY.. If you have a way to keep the dome at roughly 70-80*F the clones will root pretty nicely. If you have a way to get your hands on some hygrozyme if you are in the USA. I can't remember the name of it outside of the states, maybe someone else can fill in the blank.

Hygrozyme 1 Liter

This shit will root your clones in 5-7 days every time!! If I have a choice I do not clone without it. What cloning gel / powder did you go with? Did you presoak the cubes in 5.0-5.5 Ph water 24 hours prior to use? I have trouble with rockwool cloning so my method is soil and 2 somewhat clear plastic cubs taped together. Works great. I see roots at day 10 and wash the soil off and stick them into my DIY DWC 18 gallon tote that works great for me. Hope this helps.

In this picture you can see in the back tote where I have a few cuttings rooting right now. Notice the cuttings have the "dome" on the top to keep it humid in there. My problem is I don't have it warm enough in there. The water temps are very low and the cuttings do not have hygrozyme

I have a portable air conditioner in the room keeping the room at 76 degrees (usually 73-77) and a fan venting out the 1000W light, but its currently set at 600W
I'll move it down to 2 feet or a feet and a half from the plants, hopefully that'll help it more

I just gave them some water, with a PPM of around 500, hopefully that'll help them
But honestly, so far from the replys I have got, im not sure anyone has really figured out what my issue is : ( I appreciate all the help though

If you back your output wattage down, change to the appropriate bulb wattage. Running your 1000 watt bulb on 750 or 600 will only shorten its life.

The diagnosis from me is:

The plants are too dry... Needs a humidity dome or more sprays.

Your lights are too "hot"...
Need to take them out of the high output and place them under something a little "cooler" and "softer" like a 26 watt cfl or a 24" aquarium light or even some tube lights with "daylight" spectrum like 6500k.

Hope this helps.

I always check PH before feeding and adjust it to 5.5-5.9

also the room is air conditioned between 75-77 degrees usually
the light also has a 450cfm fan venting it which I'm told will fan out up to 2000w of light heat

I don't see or think heat is my issue, ph is always proper so unless I need to spray them with some water everyday during light I'm not sure what i'm doing wrong....

My plants seem to have gotten a little greener, my primary question is this: Does anyone here grow Rockwool in Hugo, and how often are you supposed to water your plants?
I usually give two tea-cups of water/nutrients to each plant, everyday. Is this too much? Should I be watering them once every two days?
Should I buy a measuring cup, and give them a specific amount of water/nutrients a day?
Please, I really could use the help.

Most that grow with rockwool are using hydrosystems on a timer. Getting watered multiple times a day. To answer your question, no watering once a day is not enough.
