Will need more info if you want help.
Follow the troubleshooting link in my sig, and post the info requested, back here.

'possibly' a calcium deficiency (definitely, IF you're using RO water) ... try a dose of 10ml/gal. of Cal-Mag+ ... just maybe :jointsmile:

-indoor or outdoor - indoor
-soil, soilless, or hydroponic - soil
-specific medium ???? havn't a clue
-Soil type/brand - miracle grow moisture lock
-Hydro/aero/soilless system type - none
-Anything you have added to the soil - After 3mo's of MG nutes added 1 dose of my own nutes but that was 2weeks ago.
-Soil pH - 6.6
-Water source - Faucet water thats sat for 3days
-Water pH - 7.2
-Age of plant - 3weeks in flower
-Type of fertilizer - none
-Rate of application
-Lighting source and distance from plant - 600watts all 10inches from plant
-Temperature (both day and night if you are running a dark period) - roughly 70's-82
-% Relative humidity - Used to be quite alot but I installed another fan back to normal
-Lighting schedule - 12/12
-Type of ventilation your room has - It's in a closet sooo maybe not much but I let airflow get to it and air it out.

heres some more that are rather...well dieing.

You have a K deficiency. You need some Ferts for flower. i had that same problem. check out my thread "advice please" and you will see the same spots. that gray matter is the nutes being sucked out and put into the buds or top leaves. The plant is starved.

also check during mid day. the leaves should be out flat and not droopy. droopy plants like yours needs ferts. Miracle grow is not a good medium for soil and lacks ferts needed. Go to your local Hydro store and pick some up. Any will do and if your on a budget, GH works well. Its easy but you need to know if you have hard water because there are too kinds.

If you're just basing this on looks alone, I'd say it looks like he has a Phosphorus (P) deficiency, not a Potassium (K) deficiency. K deficiencies tend to show on the leaf edges first as scorching.

Sorry my bad. thats what I meant. Just add some flower fets and it will clear that up. I had the same problem

How wet do you keep the soil? If not letting dry-out a bit, can cause root rot, and can look similar.

You'll need a bloom nutrient (fertilizer) lower in nitrogen, higher in phosphorous. There are plenty of three part fertilizer kits available. They are usually for Growth - Micronutes - Bloom. (one of the multi-part G-M-B nutrient systems, there's also 2 part, which come in an 'A' bottle, and a 'B' bottle.) Once you add the correct nutes, it should lower your water ph to within range.

Should try and find a small dedicated fan. Blowing fresh air across her helps strengthen stems, and provides vital fresh air.

Can you hold the back of your hand 10" below the light for a minute, without it getting too warm? I use a 400w, so don't know about 600's.
