yellow leafs not starting from the tip

[Guest]

my plants are in soil light ventilation and on there 2 week since germ they are developing quiet well i am leaving the water out for 48 hours befor feeding they are abbout 3 inches or so from a 600w light.It is salad crop soil with stones in the bottom hoping the soil will breath somwhat.
I started these seeds in soil because im terrified of transplanting now under the light they have been fine thriving and my friend has a similar setup and his plants are fine but mine have yellow dots on some leaves and one has started curling at the end not so much dry but looking yellow and sort of dry they have had mild mild fert previously but since then just water any idea

With only light ventilation and only 3 inches away from the light, I would guess it is heat related.Strain of Mj?
Hydroponic or soil?
From seed or clone?
Age of plant in question?
What stage (Veg/Flower; how many days into)?
Medium (Soil, Rockwool, Hydroton etc.)?
Container/Pot size?
Have they been transplanted, if so how long ago?
If soil, composition ratios (peat moss, perilite, vermiculite etc.)?
Water runoff Ph?
Nutrients added?
Ratios of nutrients (N% P% K%)?
Feeding schedule?
When were they last fed/watered?
How are you determining when to feed/water (weight, wilting, etc.)?
TDS/EC/PPM?
Tap/RO/Distilled water?
Ph before and after adding nutrients?
Is your Ph equipment properly calibrated?
Light intensity/Age of bulb/Wattage?
Distance to the canopy?
Temps at canopy?
Temps at root zone or reservoir?
Day/Night temps (Min.-Max.)?
Current air flow (CFM)?
Is there air blowing directly onto plant?
Using CO2?
Relative humidity?
Growing technique (Scrog, Sog, Supercropping etc.)?
Has plant recently been pruned, clones taken, fimmed or pinched?
Pests?
Chemicals used to irradicate?
If so,When?
Fill that out and you will get better advice...and a pic would be nice.

abbout 3 inches or so from a 600w light.It is salad crop soil

If thats a 600 watt high intensity discharge light (hid), your way too close to the seedling. If that's an incandescent bulb, you need a better light like some florescents or hid. 20-40 watts per square foot in veg and at least 50 watts per sqft for flowering. Salad crop soil sounds like crap. Transplant to something like promix or similar quality potting mix plus add some extra perlite.

I bet he was using an incandescent bulb. He was in such shame he deleted his account. Maybe he took a couple of those pointers I suggested and will get a crop.
