Hi again guys.. so the problem is back could it be a potassium deficiency?

 

[Nartak]

If it's only on older leaves or more on older leaves then i believe you are right,it is. If it's randomly appearing on tips of leaves it's Nute burn.. Is your Ph stable?

 

[Radja]

I hope so, at the beginning it was close to 6 and now it's more 6,5.Runoff water is the same as going in. I'll try taking a soil sample. I only started bloom nutrients yesterday (NPK 2-2-4) and pk 13-14. The grow nutrients I have 3-1-3

 

[Nartak]

PK 13/14 is a late flowering phase (aka Fruiting) which i believe is also on the label,unless like me u got the spanish one or something like that...

I think i used it twice,once in the start of week 5 of flowering and on week 7 on a 10week strain. It has way too much PK for early flowering stages.

User Instructions

Shake bottle well before use
Add CANNA PK 13/14 three weeks before harvesting to a full nutrition tank in the following proportion: dissolve 15 ml concentrate per 10 litre of water (1:666). Add this mixture to the nutrient for 3-6 days

This is from Canna's site.I would feed twice the amount of water you normally do and in 3-4 days when they are dry give them bloom nutes at half dose.

 

[Radja]

Okay thanks. But they started getting the symptoms again before the bloom nutrients with pk 13-14

 

[Nartak]

I hear ya,but you shouldn't use PK early,stick to your bloom nutes and time PK as labeled

 

[Radja]

Ok thx for your time
