Yellowing/pale leaves at the bottom

[badboybaz13]

Hi everyone

 

My cannabis plants are showing yellowing/pale leaves towards the bottom of the plants.

 

I'm 3.5 weeks into flower, is this normal? If not what can I do to fix it?

 

I haven't PH'd my nutrients or water in the last month.

 

I'm also using Green Planet nutrient set which includes GP3 Grow, GP3 Bloom, GP3 Micro - plus I bought GP3 Massive. I've been following their nutrient guideline this whole time and its been good till a week or so ago.

 

For my soil I'm using Coco coir premixed with 30% perlite and Canna Terra Professional. I mixed these two together and added a 50lt bag of perlite to the mix.

 

I've attached a picture if anyone can help.

If your going off recommend ŕates as per the container and not checked your EC I'm suspecting that they have been over fed causing a nutrient lock out , this means they aren't feeding at all

So the plant is feeding on itself to survive

You need to check ph and ec everything you feed

There's probably a large bulif up of salts in the medium also

So I should make sure PH is right each water and feed? How do I correct the EC?
