could these brown rusty spots come from misting the plants because they look like water drops and where the water settles (hotspots) burning the leave to give this effect not sure but hope it is
Yes you could get them from misting but i never misted my little ones my problem was defo PH related......

Do you mist them with the lights on??

my ph down says it contains sodium bisulfate, which knowing my luck, is completely wrong.

Hey dude. Flush then feed with balanced firts + 1/2 table spoon of bone meal soaked for 3-4 days min. Feed with this until trichs turn color then flush again and stop watering until soil is dry and fan leaves drop. In dark for day or two and harvest. Good luck.

Is the ph down not hydroponic ph down ??
no, i had a lot of ppl tell me that ph down didnt really matter as long as it was for water. i asked if i could go to walmart and buy the kind for hot tubs, and they said if it works for water, thats all that matters.

Well it made a diff to my babbis i think i ended up with sulfur deficiency cuz of the ph down i think you should get some hydroponic ph down and see if it helps tbf..

i got some powdered ph up and down 7 small packs for less then 15 off of eBay.. and its very potent..

1/8 tsp can bring a gal down to a 1-2 pH

i just add a few sprinkles and stir wait 15 min and check pH

You should never ever mist with the light on or at least try and mist with low light levels what light did you veg with and what light you flowering with m8?

Nigs. I say you guys don't stess, as long as the plant grows, it's gonna be damn fine, soil is quite a bit more forgiving than hydro systems I'd say, but still don't sweat it - as long as the plant is producing internodes at an okay growth rate (my plant starts 1 internode every 2 days but it's hydro) - you're all good. My fan leaves are all nuteburn and a very light green color but the plant has been growing great.
Hey that's exactly how mine is I get new branches every 2days but my leaves have yellow tips and curled downwards inwards are you sure they'll be fine I am growing in soil regular pitting soil nothing special but I am feeding it tiger bloom..
Should I quit stressing and let nature take its place???

I begged with a regular cfl 23w believe it or not kept it really close to the light for 2months and now for flowering I'm using the same one but 4 of them?

any additional input on this topic would be appreciated it..

the ph up and down that i got off ebay was listed at Hydroponic up and down, although it is a granular , up looks like a corn starch texture and down looks like a table salt texture...
