Deficiency help please

jg106256 · Dec 13, 2020

I'm using coasts of Maine platinum blend soil.
Everything was great for a couple months.
Now it's almost month 4 and I've got deficiency issues.
Can anyone offer advice please?

I’m unfamiliar with your medium. Is this a fortified soil with nutrients already in it? Are you feeding?

Yes its all in one, "only add water" soils that was designed for mmj growing.
I've only given filtered water.
Everything was going wonderfully and now the decline of the last few weeks.
Thinking of trying a kelp foliar feed to reverse this curse.

Suggest instead a feeding using Lucas formula. Micros and Bloom only. Requires a 3-part nutrient system. Others might have suggestions for a straight P/K feeding. But this won’t be the last feed they’ll need.
