[xr4x4_0]

Hi this is my second grow of zkittlez auto. its 2 weeks into flower and I think I have a problem with some leaves but not sure what it is. I have read up and seems like a cal problem but I am feeding calmag every time I water and its been fine until a few days ago please could you look at the photos and let me know what you think thanks guys

Medium and ph?

The clawing leaf tips look like Nitrogen Toxicity.

Ok so do you think that is also causing the yellow/brown on the leaves thanks

Your pH is too high for coco.......should be around 5.8 - 6.0.
Are you feeding daily to run off?
Do you ever give plain water?
Is your pH meter calibrated?

Calmag probably.

I'd start giving them more calmag and cut down on the N. You may have to flush to get the excess N out for now but idk.

It doesn't matter
Just carry on and pluck the dam leaf if it offends your eye

Its having feed every 2 days to runoff as the pot drys out. I gave plain water last week to flush and to be honest I dont know if the pH tester is calibrated I will look in getting some cal fluid

You shouldn't let coco dry
It needs watered daily and why on earth are you talking about flushing your plants?

My feed chart says to flush before changing to the flower nutes and I had read that weed likes a wet dry cycle thats why I was letting it dry. So if I water daily should I do that to runoff? and should I feed every time? Thanks

Yes
and not sure about products you are using but typically both grow and bloom are combined for the first few weeks of 12/12

Ok thanks for that. im using flora 3 part micro, grow and bloom the strength of each changes for each stage of growth. So would you feed everyday or keep to every 2 days and plain water in-between. Thanks

P.s the plant is an auto so no 12/12

I feed lighter than recommended every day when in coco
I switched to a peat based product so I can water less

You're treating your coco like soil.........it's drain to waste hydroponics and shouldn't be treated like soil.

Coco basics:
Feed daily to substantial run off using a pH around 6.0.........twice a day in flower to run off.
Never give plain water.
Never, ever let the coco get dry.

Allowing the coco to dry will cause salt build up and lots of problems for your plant.
Feeding daily to run off replenishes the nutes, pulls in fresh oxygen to the roots, and prevents salt build up.

This is the best place I know to learn the proper way to grow in coco........www.cocoforcannabis.com.
They also have a proven feeding chart using the same nutes that you do.

Good luck.
