Help needed ... what have i done wrong

Hi, been browsing this site for a few days after stumbling across it and i have to say its brill so i have joined and hope someone can help, i have a couple of plants on my 1st attempt at growing that have problems and any input would be appreciated. They are under a 600w sunmaster hps bulb in veg, i know from reading here its the wrong type of bulb and will replace it with a mh when i can get one, temp is 76 and rh is 65%, there is an ocillating fan in the room also. one is in soil and perlite mix and for food i'm using miracle grow plant food ph'd to 7, ec is 12 and gets water every 2 days and food every 2nd water. Other is in dwc and gets bioponic grow nute at 14ec and ph'd to 5.8 Hope i've given enough info but if you need anymore just let me know.

uhhh nothing lol...u could bring the ph down to about 6.5

So whats causing the yellow on the leaves in the soil and the brown burnt leaves in the dwc, light is approx 24" away from plants by the way.

you said u water it every 2 days, u should water it every 3-4 days, so u might be having a over water problem. 2 days is to much

If i drop the watering to 4 days would i feed each time or still feed every 2nd watering, thanks for the quick response by the way

feeding it each time is not a problem but do it and see what happens, dont over feed it tho, no problem

I just started growing in an aerogarden about 2 weeks ago, and just noticed today that the stem to one plant is beginning to have a build up of some kind of white substance crusted on it. any suggestions?

does it look liek its peeling from the stem, if it does then its the stems (skin) peeling of and growing bigger...but if its like white craps on it then it might be mold

no i dont think its peeling, i touched it and it came off on my fingers, its a dry crusty texture. I used bottled spring water so i dont think its calcium, if its mold how would i go about getting rid of it?

When you say the EC is 12 and 14, do you mean 1.2 and 1.4? If not, then you are burning the hell out of your plants. I think you probably need to do some serious flushing on them and use way way less fertilizer.

Sorry mate, yes i meant 1.2 and 1.4

Dont mean to be a pain ecabraisas but could you post your own thread about your problem as i get an email telling me someone has replied and when i check it out they're answering your problem not mine

Not yet mate, will take some tomorrow and post here, i've dropped the ph to 6.5 now so we'll see if that helps.

Thx for the heads up on the nutes, is fox farms available in the uk or can someone recommend a good substitute. How often should they be flushed and roughly how much water should i use, they are in 3 gallon tubs.

Here are some more pics, nutrient changed in dwc and ph is 5.8 ec is 1.2
Changed wate and food ph to 6.5 for the soil grow, seems better but still got yellowing on tips of new growth, might have to wait a bit longer for changes to kick in.

Heres a pic of my clones 1 week into soil and some more ready to go into soil or hydro, not decided which yet lol
