Hello, welcome to iLGM, let’s see if we can get some help.

Wow, really?

Did you get run off pH and TDS?

@Covertgrower need a lil hand, thanks :v::green_heart:


How close is your light?

Exactly what I was going to ask.

How about an overall picture of the plant in white light?


I just got a ph and tds tester yesterday and I’ve been using tap not distilled I just recently started monitoring my levels so there’s no sure way of telling exactly what’s been getting to it. I tested my run off for ppm yesterday I started at 600 and the run off was 300 something so their absorbing nutrients so the ph should be ok idk what else to do or what could be happening.

Welcome to the forum.
They are asking how close your light is because it looks like heat stress on those leaves.

Thanks! My lights are probably 6in from em the others are about 18in above their led tho and don’t put off hardly any heat

The strain is mac an cheese given to me by a buddy,

I’m using fox farm happy frog soil

Their in 7gal plant bags

I haven’t had a steady method of ph besides the color drops just recently bought ph meter and ppm meter but I normally shoot for 6.5

Don’t know the exact ppm

Their all indoor

I have a marshydro sp-150 and a mars hydro ts-600

Temps normally 75 - 80

Humidity is lower 50 sometimes drops as low as 30 or 40 buying a humidifier here shortly

For the ventilation I’m using a 10ft x 13ft grow room and I only have a box fan blowing down on my plants to help with rare high humidity situations but the fan is always on and I have my house ac/heat vent in the room as well.

I’ll take pictures of entire set up and separate plants here in just a minute.

I would recommend to raise that light. 18”-24” is adequate.


That’s not what’s causing the issue though or is it?

Another thing is the clones i took off the same plants are looking the same and my 2 plants that are about a month is starting to do the same so i dont think its heat burn from the lights its something else

These lower leaves, does the white looking stuff in the leaf wipe off? How high has your humidity been? I see 50% is that an average or does it go higher?

@Covertgrower. @Myfriendis410 @MattyBear @Bulldognuts @kaptain3d. Any thoughts? Please see above light colored abnormal top growth pics in post#11 as well as the others​:v::green_heart:


Looks like WPM to me. Mild peroxide and water treatment and increased airflow/lower RH should help.


The white powdery substance doesn’t bring anything to mind aside from WPM. I saw 50% rh but saw where there was talk of getting a humidifier. Has the rh been higher than 50% since starting humidifier.

Ive seen it as low as 35% before and it really doesnt hold steady if it rains itll be higher if i just watered itd raise but other than that i say it hasnt gotten over 40% in awhile
