damn, damn!

I cannot seem to get the hang of growing weed indoors..I use the less intense cooler lights...follow all the instructions of growing, am a avid gardener anyway, yet still cannot get it right.
My cannabis plants white shark, are getting brown & crispy on the edges yet again..I lost the last lot.
don`t want to lose these too, its so frustrating. I use an ionic feed & follow the instructions too...so what am I doing wrong?

Nutrient burn..feed at half the recommended dose

yep, you are feeding too much.

its not always about following instructions on a bottle...start off with 1/4 dose than work you way up...better to give less nutes, more often than too much at once...flush your soil with just water asap until run off comes out clear...wait til soil is dry than feed...and don't use full strength nutrients...as you are seeing its too hot!

Nutirent burn because of the yellowing of tips and some of the leaves are at advance stage of toxicity. I would leech your soil. Reintroduce very mild form of nutrient solution then when you get back to your feeding regimen recalculate and dilute it by half.

You bumped up the feed and burnt them, next time go by the label and use perlite.Also get some fans in there and run them 24/7, you got mold all over the leaves.

good eye budz. i would pull them and clean like hell.

Thanks for your help..I`ve obviously been too enthusiastic in feeding.

What kind of mold do I have then, I can`t see where it is?

I forgot to say, I use a fan all the time..27/7!

i alwasys start a nutes cycle with a 1/4 teaspoon per gallon and move it up to a full one after a few weeks.


mold is the white stuff all over the leaves. too humid in the grow room? not letting the soil dry out before watering? it also could be thrip larvae.. try to get a closer look .. but i think he is right .. mold

what kind of mold, & what can I do about it?

Doesn't matter what kind of mold you have, mold is mold and it's bad for your plants.

You seem to have; overnuted, possibly heat stressed, possibly overwatered and you have a high humidity/mold problem. You can fix the first three but #4 is the one you need to investigate pronto. Perfecting your plants growing environment should be job #1 for you.
