My girls are in about week 3 and I'm running into issues. Some of my leaves started out getting brown spots, that are turning into small holes. Not all of them but some. A couple have no visual issues. This is my first grow so any advice would be welcomed.

DWC

Water temp 63-65

Ph started at 5.5 but just recently bumped to 6.0 for maybe cal deficiency.

Using flora bloom series with there entire line that they suggest at the suggested levels.

Adding calimagic

ppm 1100-1150 general hydro suggested number

Under t5 4ft 8bulb for veg and moving to tent with two 600 for flower, if I make it that far. Light is about 18-20 inches away.

Light on temp around 70-75
RH 35-40ish

Roots seem good. No breaking and no slime. The color is from the nutrients.

Thanks for the help
