Brown spotting

I got 2 plants in a hydroponic system both are running on same water system but one plant is growing lot fast but showing ma deficiency. Plant 30 days old auto flowers

Looks like calcium deficiency. Maybe increase base nutrients slightly and see if new growth stops doing it? First make sure your pH is within a acceptable range 5.5-6.0.

What kind of Hydroponic nutrients do I need i ran out of what the thing came with. Had a and b. It needs something stronger. I got more lights too. Just what kind of nuts do I need to get

First off, rip out whatever that is growing next to your pot plant.

Buy more A & B nutrients, I use Canna, solely because they add Si (Silicon) and no other manufacturer does this as far as I am aware. As for something 'stronger' , boosts are a rip off, I add triacontanol as it has gives the SAR effect (systemic acquired resistance) to the plants which is highly beneficial without any doubts at all.
