You look short on Ca.
You look to be long on pests (mites); I'd look this plant over super carefully.
And while your temps are decent, you may have a smidge too much light based on your leaf margins.

You've got one hell of a bush; good luck!

I looked carefully under the leaves, but I didn't see anything harmful. Or eggs. Are you sure they have pests? I think calcium. Do I only need to use Epsom salt?

i think one problem is your EC is way too high. almost 2.0 try about half that. i rarely go above 1.2 EC

and temps are too low in the room. go for about 75F, not 65F

Actucally my room 73-78f and
EC 1.7-1.9, In the meantime I use tap water 160PPM?? I'm thinking about flush the roots tonight and using R.O water?
I thought it was perfectly normal during the flowering period?

post 1 said temp was 65F. 73 to 78 is fine.
i thought i saw some brown leaf tips. that would be too high EC

and the leaf edges curling up. how far away is your light from the plant?

the rust spots looks like not enough Ca. and the leafs with holes could be bugs? do you have a pocket microscope to look at the underside of the leaves? you can't see mites with naked eye

and what is your EC doing? dropping, rising or staying the same?

I dropped the EC to 1.5.
I don't think there's more nutrients.
It looks like she wants more nute.
I have a microscope. But there are many leaves. This tree is too big, dude:)
I looked at it. I haven't seen anything yet. I should use neem oil. Any ideas?

Yes I checked the hole leaves.
Ec never falls. My plant is drinking 2.5-3lt of water a every day. When I complete the missing water, I add cal-mag and b52 as nutes.I haven't used a fan in the room for a while because it makes a lot of noise. And some leaves look wet(transpiration) . Could it be about that?

i like running dwc so that the EC is dropping every day.

for you Ca problem, foliar feed your plant when lights are on with cal/mg and water. it will fix it faster than thru the roots.

and how close is the light to the plants? i think the leaf edges curling up are too hot conditions from the light being too close.

Could it be a fungus because there was no air circulation?

When the the serrated edges of marijuana leaves curls or tippedup like that, it's often a sign of temperature stress, overwatering/root problems or extreme humidity levels.

so temp stress? it doesn't seem like it. 50 cm from light to plant is good. 73F is good.
overwatering? only for soil plants
humidity? could be lack of a fan/ air circulation. i'd run the fan again.

and a fungus i think you would be able to see with your eye.

Thanks for time dude!
I hope the problem is eliminated when I start the fan.Do you think it looks like a serious problem? Does it affect harvest? And finally, it doesn't seem like a bug problem, does it?

no problem. it doesn't look serious but i always try to fix even the small problems before i flower a plant.

it could be bugs but only you can figure that out. you have to look at a bunch of leaves to really know for sure.

Allright bro, I will do.What do you suggest I use as a precaution for mites? (neem oil)?
Estimate how much can I harvest from this plant?
