Having issues with a couple of my crypts, leaves have started to go yellow and some are getting holes. They have been in the tank for a few months and fine up till now.

Please see pic

Many thanks

Looks like unadapted leaves,to me.
Just pull them off,giving those fully adapted more slender/darker leaves ,more space.

I'll give that a try thanks, you don't think they are lacking something nutrient wise??

Advice as above really. New growth on the crypts looks ok to me and I'm assuming you're still using tnc complete for fertiliser?

I am John yes, I am dosing 700ml per week plus root tabs however I am wondering if I should add more tnc as my nitrates are at almost zero withing a few days

Whoooo tnc are going to love you dosing their product in a 700L tank £££££ lol.

I don't think you need to add any more mate, especially considering you're adding root tabs. Here's what's being added every week.

Possibly a bit light on iron but I reckon it's enough for low tech. Potassium, mmm lots of that.
For a tank this size you definitely need to look into dry salts, it will save you a fortune mate.
I don't have the time atm to post any links to diy ferts but have a read in the aquarium fert dosing threads.
Failing that somebody will steer you in the right direction.

Edit: 700ml a week? You're adding way to much, that wants reducing by at least 50 %.
That's what happens when you rush, 250ml a week is plenty for that tank @Mattant1994 sorry for the confusion.

Thanks John, I was thinking I was using quite a bit lol.

I do agree I need to look into the dry ferts so will take a look into them.

My mistake as well it was meant to say 70ml per week lol. Blimey 700ml would be a serious amount 🤣🤣
