Help Me! First Grow. black spots. First Week Flowering.B

Hi everyone and anyone. I am at the end of my first week of flowering. I had noticed a little yellowing on one plant a couple days ago. Today there are spots in a few places on one plant and one spot on the other plant here are some Pics.

Help me, Owe-me-one Canndoobie, you're my only hope!

you are feeding too much
what are you feeding and how much,when?.
deffo too much food, i cut down to half the rec dose and as the plant grows/flowers, maybe add a little more.
every other water
i water every 3 days or so.

some plants go yellow"well the fan leaves do, but only at the later stages of flowering, when you stop feeding, and the plant eats up all its food left in resurves.
but i think too much food.

yellowing is normal in flowering,but it loks like mold whats the temp and humidity?? i would cut that leaf off ASAP.GL PM ME IF NEED HELP.

BTW I am growing in organic soil mix mixed with perlite(70/30). I used Earth Juice bloom with my last water(under 15mL/gallon of water. Which watered 3 MJ plants and a dieffenbachia. All in 3 Galloon pots)

I was thinking it could be fungus, root rot (I don't think I am overwatering but this my first grow.), Nute Def., PH Problem (6.9 currently.) or some unknown. I haven't noticed any little bugs or larvae anywhere...


Any input would be appreciated.

Thanks for the quick response everyone!! For those that think over feeding...Do you think I should flush the soil? I have distilled water on hand if needed.


Temp runs between 75-85 depending whether the light is on or not. (400watt HPS BTW) I could tell you wnat the actual humidity is but its a basement and its not super dry or super damp.


Ill Chop the leaves now. they have only been in the Dark cycle for 10 min.

That is not overfeeding.. Overfeding starts at tips of leaves and the leaves will appear fried at the tips.

I would be careful about cutting. You can trim the damaged parts off the leaf instead of cutting the whole thing.

It looks like a deficiency or mold. I would try to establish a plan based on nutrient deficiency page in GROWFAQ before you just dive into flushing.

cutting 1 leaf will not cause stress,,but if its mold are a fungus u dont want it to spread.make sure u wash watever u use and hands b4 touchin the plant are plants,GL

i would just flush just in case, and also cut the leaf off, it wont hurt the plant at all.
also have you got a fan in your grow room?.
