I started noticing the problem pretty much the same time I put the plants into flower. It started slow but over the last week I have seen damage starting to happen on most fan leaves.
I have 3 plants. 1x caramelo 1x northern light and 1x big bud. The caramelo got repotted into an 11l pot a week ago and the other 2 were potted into there 6l pots about 7 weeks ago, 2 weeks before 12/12. I'm gonna repot them but I need to buy the pots first. This week hopefully...
At first I thought it could be nutrient burn so on there last water I just gave them a plain feed but that seems to have made the leaves start to turn yellow instead of just brown. So that got me to thinking it could be a deficiency because I've only been feeding with a half measure of nutes.
I don't know if it could be anything to do with Ph levels, I have a liquid testers but it's hard to tell the result... I think around 6.5 - 7.0. I know its a big difference but im gonna buy a better test right away.
Here are the pictures... I'll let the knowledgeable decide...
Heres a picture of the Ph results, looks about 6.5?
How it started...
This is how most leaves look
And a couple shots of the yellowing seen after the last plain feed
So do you think it's deficiency due to under feeding and the soil being all used up?
I should also mention the the soil is quite compact and hard when it's dry... I read that can lockout some nutrients...
I know it's quite late but I know none of you are asleep lol Hopefully anyway
