those are usually signs of watering too frequently..
maybe need an extra day or two between watering?

hmmm other than the rust spotting i havent noticed signs of overwater. Am i making the soil too hot from the over water/feed? I was having trouble feeding 2x per week per the FF schedule so I was pushing water/food down every every 3 days or so.

Am I overwatering from volume or frequency?

GNick55 · Mar 22, 2021

i’d say so,
do your leaves have more of a droop look than say praying to the light? more often than not?
if you’ve notice your leaves kinda getting droopy or hanging downward after watering instead of praying like, it’s a sign of watering to soon.
you’ll know you nailed your watering by the plant when the leaves don’t droop after watering..
she doesn’t skip a beat!

that makes alot more sense. I have 3 plants in flower, and all 3 seems to be different state: 1st plant is the pictures above showing rusting, another plant is praying to the light, and then the 3rd plant is droopy. I am going to let the plants get alot more needy before watering. Should I feed water+calmag only for this next watering?

no just keep what your doing when its time to water/feed..
doesn’t look like your burning/over feeding,
just watering too frequently..
you’ll may start to notice now that as the soil starts to get drier the plant looks better/healthier, generally in most cases, as marijuana likes it kinda dry.. in nature gravity is constantly pulling moisture away from the roots which oxygen will take over that spot..
not sure if i’ve said this, but say you knew you should of watered a plant because it was dry but she was praying, so you left it for the night, woke up and she is so sad droopy looking from drying out too long, so you water her, in a few hours she’s all back to normal in less than day, frequently watering will stall growth and create problems that could go on for 2-3 weeks..
if your growing in bags you can always point/put a fan up against the bag the help push oxygen in there and with drier quicker..

thank you for your help. i plan on just going a wee bit longer inbetween water/feed and see how we do.

absolutely and keep us posted, about anything your wondering about too, post it!
nothing is stupid..

GNick55 · Mar 22, 2021

you can snip off up to 4-5 leaves off each plant, only if they are in more bad shape than good, as the plant can still feed from them.
but you don’t really want rotting or weak in health leaves on her too long.

kyLman · Mar 23, 2021

here's what she looked like as the lights kicked on 12 minutes ago.... I wish there was more I could do. I turned both fans on full blast, aimed at the pot containers. Is there anything more that I can do? Am I going to lose the two bad ones?

GNick55 · Mar 23, 2021

ok, just give me a bit in case no one gets to you.
also i’ll have to re read your thread.
how do the pots feel in weight?

ok, i haven’t got ready yet or re read your thread either..
so if you haven’t can you list what you feed her or take pictures and how much, ml/gallon.
you could be high in nitrogen with the leaves getting the eagle claw, also caused by overwatering.
i’ll be back in bit, not to long.

If your in soil you should wait to water until the pots feels pretty light. If you lift the pot and it’s really light it’s time to water.

I'm using the above pretty much to a T. I am on "week 7" on this chart, so the third week of flower. Am I going to lose the plant? Can I lower the humidity and add temp to dry the pots out quicker?

Big Bloom = 0-.5-.7
Grow Big =6-4-4
Tiger Bloom = 2-8-4

GNick55 · Mar 23, 2021

geez that seems like a lot, you could probably get away with just using the tiger bloom, but it seems to be working as your tips are not burnt.,
i did look over your thread here, and did google a bit. i’m sticking with letting it dry out till you feel it’s dry/light..
you were getting away with watering so much during veg but it was fine but now in flower is where things change for the plant and this is when this issue arose.
like i said before she’ll be sad for a bit and damaged leaves will get worse, your new still needs a few days to really see what is happening, to me all you can is provide a nice environment and wait..
there is people watching this thread and if they feel i’m wrong than they will jump in and correct me..
