First month into my first grow. Just topped and need opinions on a few things

a few of my leaves on just one of the plants is showing problems. I just topped my plants today and I’m hoping I didn’t mess anything up. Other then accidentally snipping a leaf. I’m using General hydroponics nutrients along with their pH up and down. I have three SF 1000 and a additional supplementary mars Hydro LED

Also I would like to specify that I’m growing white widow from ilgm. Also I’m not sure if I have nutrient burn or too much potassium or something

I think the lights are too close or maybe potassium deficiency.

A single SF1000 can put 972 µmol/m2/s at 12" on the center according to their website, that's a DLI of 65 moles per day with 18/6 schedule, it's almost the top threshold for photosynthesis using co2.

Magnesium deficiency. You can foliar spray Epsom salts. 1 tablespoon per gallon of water. Add a drop of liquid soap in the spray bottle. Use only Epsom that doesn’t have any scents added.

I release co2 right when the lights turn on from my old kegerator co2 tank. But it’s either a potassium or magnesium deficiency or could be something caused by pH and lights. Gonna get some salts

I was thinking possibly magnesium or potassium deficiency and it’s only one of the plants showing the issue though

Then that’s the only one I’d treat. If more issues arise you might consider pH.

She’s come a long way

Awwi see your growing god's gift to man

The first cut should always be a FIM my opinion

1 month into flowering
