First Time Growing, I Need Some Help. PLZ

So they arre 4-5 weeks old under 400 watt cool tube, ph 5.9, Ec 1.1

I have know idea if they are nute burnt, or under nute.

thats nute burn.

what are you feeding?
what volume per gallon or liter?
when was your last reservoir change?
ph 5.9 is a little acidy for hydro, but it's prolly from the moss your using instead of rockwool perlite or hydroton

also is the 400watts REALLY 400 watts and if so what kind of light (hps, mh incandescent, LED or fluorescent) and how far is the light form those plants?

cus some of those leafs look like they got sunburnt.

The spots are a fungal infection, check the roots and your res is a pathogen soup. Get some H202 asap.

Fox Farm, 1.5 Gallons, 1 week ago, What should my pH be? 400 Watt HPS about 2 feet away on 75% power, Hydroton, hydrogen peroxide? how much should i use?

4400 watt hps at 2 feet is fine after a week or so, but that much light that close to new spouts can cause damage. next time, when you put the plants under your hot lights, keep the light farther away, like 36-40 inches until the plants acclimatize.

a1.5 gallon rez will go flat fast. i use dwc with a 5 gallon rez for each plant and change the water once every 2 weeks until they get ready for big growth then every week, until harvest. consider a larger reservoir or much more frequent solution changes.

hydroton is the clay orchid pebbbles used to provide a stable platform for your plants in most DWC and Ebb and Drain hydroponics systems, they dont soak up water, and add mass and something for your roots to hols so your big dope trees dont fall over.

using highly absorptive materials (like coco coir, or moss) will soak up shitloads of water and keep it on the upper rootzone encouraging fungus and mould. what you got there looks like sphagnum moss which will also raise your acidity when the tannins leech out into your rez.

i usually shoot for a straight 7 neutral ph in my dwc's but some say the target should be 6.5 to 6.8. it varies. when you get down around six i get nervous, cuz thats a little sour. some funk loves acidy solutions and when it gets down around 5 your roots will start burning.

Thanks For Your help every one! They Already Are Looking Better.
