How much nitrogen is in your nutrients? Edit: I see it is 4-3-3.

Yellowing, Browning & Death of Lower Leaves: This is generally caused by nitrogen or iron deficiency. Pot-bound plants are especially susceptible. Regular application of fertilizer and repotting periodically in fresh soil avoids this problem.

Maybe try a tiny bit of soluble fertilizer with 10-10-10 and see if some extra nitrogen will help.

Thank you armanidog! Picking up my PH up today and will give it some nutes.

 

[Phrygian]

Picked up some PH up and gave it 2.25 L of water and 10 ml total nutes. PH'd to 6.5. I noticed a lot more water run off this time.

 

[Phrygian]

Before I started I was paranoid about over watering and giving too much nutes. It seems I did the exact opposite. A bunch of leaves look a little rough, but I think she'll be ok

Day 31. Another watering this morning, a little over 2 L and 15 ml total of nutes. Was pretty dry today. Do notice some definite vertical growth now! Been raising the overhead lights a tiny bit each day.

Welcome to AFN Canna I did the same thing. Went from too much water, then not enough water and nutes. Now I'm running with a modified version of Tang's AN feed schedule and things seem better. Other ta a few rough looking leaves, your girls is looking good. But you may a lockout issue going on. Do you have a way to measure the pH of your soil?

 

[Phrygian]

Thanks! Just lately I've measured the run off. It was about 6.2. Water with nutes ph'd to 6.5

You should be really pleased, it's good work. Enjoy the rest of your grow.

 

[Duckster]

Thanks! Just lately I've measured the run off. It was about 6.2. Water with nutes ph'd to 6.5

If the water/nutes went in at 6.5 and came out at 6.2, that means the soil is probably down around 5.9-6.0. Some nuts are locked out at that level. You might want to raise the pH of what you put in to 6.8-6.9. That should to bring the soil pH up a bit. But just my 2 cents. lol
Cheers

I'm glad I'm reading this. The whole pH thing is kicking my ass. That clicked Thanks man
