Deficiency in late flower

Hi guys, over the last week I have noticed a deficiency on the top of one of my plants and it's only getting worse. It is in late flower and not far away from getting chopped. I'm guessing it is a immobile nutrient deficiency since it's on the top of the plant? I'm growing in coco and feeding until run off daily. The temps are around 28c/82f. The humidity is between 50% and 60% and the PH is 6.0. I heard that towards the end of flower they can get a calcium deficiency which is normal but I'm not 100% sure if that's true or not. The rest of my plants are green and healthy so I'm not sure what's up with this plant. I could always raise my EC from 1.2 to 1.3 and see if that helps her? Any help is appreciated. :blsmoke:

Feed 2 times a day do not raise ec. Once a day for a flowering plant in coco is probably not enough. Most coco growers are feeding 2 or 3 times a day

I don't have a irrigation system yet and I can only feed them once a day until run off due to the fact that I have to take the plants out of the tent to feed the ones at the back and all of the buds are starting to bend downwards now due to the weight of them. And when I take them out of the tent it stinks the whole house out so I can only feed them once a day dude. But when I get my irrigation system setup on my next grow I will start feeding them 2 or 3 times a day. They have been fine up until this point all the way through flower they have been fine with 1 feed per day. Should I check the run off EC tomorrow and see what it comes out at and if it's a little bit low then give her slightly more feed?

Well see the issue is not that the feed is 2 weak. It's that coco doesn't retain much water. So the plant is smashing the nutrients dissolved in that little bit of water the coco holds faster than it drinks all the water. Leaving it wet but hungry. If you up the ec you might start to claw and lockout due to high ec.

You can try 2 up the ec but but it's truly not gonna provide much more food, and it will likely make eating harder on the plant.

I just don't know what to do then because there's no way I can feed twice a day until I get my irrigation system. I have the run to waste system I just need the irrigation system now.

Don't feed to run off if that's what u gotta do. If u can get up in the morning and give them a gallon or half a gallon without it making a mess and it running everywhere then do that. And feed to run off later like you normally do

Fill up a one gallon jug. Water till it starts to run off. Mark a inch above that spot. Fill the jug back up. Dump into another jug down to your Mark. Now on the second jug mark your level. That's what you can feed without a mess real quick to each pot

Making a mess isn't a problem for me dude, I've got a drain to waste system so the plants sit in saucers that are connected to pipe work and then it goes into a reservoir where it's jetted out the tent with a pump. It's mainly the smell that's my concern because when I open the tent they smell very gassy and stink the whole house out.

So you have 2 move the back ones to the saucers to feed? Or are they already hooked up 2 the waste system? I'm a little confused? I was suggesting crawling back there without moving them and just giving them enough to not cause run off.

I have two plants at the front and to get to the ones at the back I have to take out the 2 front plants. They are connected to this system. It's impossible to get to the ones at the back without taking at least 1 plant out

how aboutt the whole plant

They are in the dark at the moment and I don't want to disturb them. It's literally just on the top few leaves at the top of the plant where the big bud is. The rest of the leaves are green dude. I'm guessing it's an immobile nutrient deficiency and it needs feeding slightly more to prevent it from spreading to the rest of the plant?

just as an example, here's my 5 guesses :

overfeeding led to lock out
pH not in range or not accurate
Ca deficiency not treated
Mg deficiency (leaf on bottom right kinda out of focus)
root issues

or mix and match all 5

I raised the EC from 1.2 to 1.3 for 1 day just to give them a slight boost but they were fine for about a week or two after that so I don't think it's a lockout issue. the PH is 6.0 and has been all the way through so it's 100% not a PH issue. I'm thinking it's a calcium or magnesium deficiency myself and they need more feed because the buds are putting on weight now.

I only fed them 1ml extra of A&B per 10 liters of water just to give them a slight boost which is only 0.1ml per liter so I don't think it could be lockout but it's always a possibility? I'm guessing that it's some sort of deficiency and they need more feed because that's how I normally fix the issue lol :bigjoint:
