ARRGH....can someone take a look. Pics too!

Not quite a week ago I got some clones that were rooted in rockwool. 2 Sour Diesel and 2 MK Ultra. Also have an unknown very small clone, so 5 total. All plants have received same treatment so I will cover them all for comparison purposes.
- CLones were all 3 to 4.75 inches tall, except for the unknown which is only 1 inch.
- Planted in SuperSoil with 25% perilite, says on the bag the soil is sterile and contains NPK as 0.14-0.08-0.03 with a PH of 6-6.5 but no mention of trace minerals.
- Watered with RO water at roughly 6.25 PH and 1/3 of recommended nutes with trace added. Also added some Epsom and some diluted dolomite lime. Then I got burned tips on new growth and have stopped all adding other than a little H2O2 and some Epsom.
- At first I watered too much per watering causing the water to seep down to the bottom where the roots still cannot reach it while the plants would dry out (hey, I'm a beginner). I'm now watering them more often but very little at a time. My pots are still heavy from the water down low though.
- Lighting is one 100W CFL (~6500 usable lumens) roughly 3 inches from closest plant running 24/7.
- I'm training all of them gently, hence the odd angled stems.
- Weather has been hot and my shed is not air conditioned, occasionally over 95 degrees. Humidity is typically low here also. I can't afford to insulate and buy an AC and humidifier so just waiting for weather to cool.
- clones came with Spider Mites which I detected right away and using neem oil to combat but damage was already done to older leaves.

The Sour Diesel in particular looks bad with very very little growth so far. The little bit of new growth I have gotten does look much better than the existing older leaves but are curling under and some are twisting a bit, and again - they are barely growing.
The older leaves are in much worse shape, droopy and very pale. On some of them the paleness is far more towards the stem getting greener towards the tip. But again, overall droopy and pale and generally weak and I'm not sure which way it's going at this point.

The MK is doing a little bit better in terms of overall looks and vitality but also is not really growing much, but at least not looking like it's dying. The little bit of new growth does look relatively good except for the little nute burns on the tips.

The unknown one also isn't growing and now has the burned tips too.

So, can I pull out of this by just continuing to feed nothing but water in very limited amounts? Or do I need to flush? I hate the idea of flushing because with the plants so small my soil will then be wet for a loooong time and I worry about what that will do. I just don't know if particularly the Sour Diesel's will pull through.
Also, what kind of growth should I expect? I thought these things would take off pretty quickly but eeehhh, not so much.:mad:

It's been hard to find an exact 'recipe' for newly planted clones, maybe I'm just completely f'ing this up despite all my reading. I looked at the big deficiency guide but it's so damn hard, looks to me like I got a little bit of every problem in there! :wtf:

please see attached pics, the file names should explain what you're looking at. These are Hi-Res so you can zoom all you want.

Thanks in advance,

with the ferts in the soil, you really shouldnt feed them for a few weeks, with such a small root system that clones have they do burn easily

adding epsom salts all the time is not a good idea, you can not only build up a toxicity but if I remember correctly too much magnesium will lockout potassium(that you can lookup)

additionally you made to mention of PH other than what was printed on the soil package. Ph & over fertilization are the 2 most common mistakes , PH being over looked the most

everything that goes in your pots should be PH adjusted to the optimum PH zone of 6.5 - 6.8 for soil growing, this is most important for container growing, your leaves are showing some twisting that may in fact be ph related & also could be the contributing factor of the general health of your clones

I would complete a soil runoff test to know the PH (which maybe acidic from your ferts that wernt ph corrected)ferts are almost always acidic

To rule out PH related issues complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....

To add to Ganja's post. Once you test your runoff PH and see that its at about 4-5, Then I would recommend flushing with reg. tap water(declorinated). You have to flush 2-3 times the container size to remove excess salts that build up. If your worried about drowning your baby's(and you should be), Then try my method: at the end of the flush pour some diluted H2O2 through and then take a water bottle which you drank about half of (you know the one, that half bottle of "stale" water sitting next to your bed on the table), Pour that through last. Its important that you drank from this container, The germs in your saliva will multiply in stagnant water, pouring it on after the H2O2 ensures that the extra O2 molecule will have some bacteria to react with and release the O2.
I started that method because I never heard the peroxide actually reacting to the soil.

Thanks guys. I have actually been PH testing and adjusting all my water after adding the various nutes. PH would generally be a little too high so I have used a little vinegar to lower to about 6.25 each time.

To get the runoff test done I have to soak my babies and it scares the hell out of me. The roots are still small so what if I took some dirt from the pots and soaked it in neutral water for a while and then tested that ? (anything to avoid soaking!)

Thanks again

[Zcomp]

That will probably work but you don't want neutral water. You want PH corrected(6.5-6.8) water.

dont be afraid to flush, flushing is like cleaning, its no different than 2 days straight rain ...yeah?

and your correcting a little low optimum PH is 6.5 - 6.8 for soil
vinegar is not the best choice for correcting, its works yes, but why not add something benificial to the water instead of something the plants not interested in.

PH down (phosphoric acid based ph down) is the best to use as our plants use large quantities of phosphorus throughout its life cycles

for ph up one should use a potassium based ph corrector as again the plants use large quantities of potassium

making a slurry and testing the PH of it will work fine
