Feeding regime/timings - possible N deficiency ?

[JimmyPage]

1m x 1m tent

Lumatek 600W LED (set at 75%) and 1m above plant.

Shogun soft water nutes in a bubbler.

Having grown the last two times under permanent 12/12, this grow is going old school 18/6 then 12/12.

Currently week 3 in the tent.

 

 

 

Have switched to Shogun nutes after using Vitalink for years.

 

have always changed buckets once a week with fresh nutes. Have never topped up during the week.

 

However, now I am convinced I am seeing some N deficiency. Researching makes me wonder if I should add some more nutes before the 7 days are up. Guided by the EC ?

 

So check EC of a fresh batch, and then if it falls, top up the mix with some more nutes ?

 

What's the communities thoughts ?

 

When I first started, it was someone here who said change the nutes fresh and not try to balance with this that and the other as you don't know what the plant takes and when.
