Light spots on lower leaves

[Budder Fingers]

Ok, been going round in circles trying to find an answer, any help would be greatly appreciated.

3rd week of flower, my crop is starting to look unhealthy from the bottom up

400w HPS, 2 x 350w Kessil Magenta LEDs
temp 80f
humidity 45%
equal parts coco/peat/perlite with some WC and compost
earth juice grow and bloom.
blackstrap molasses
roots organics trinity
some protekt

I did foliar spray a few times with alaska pure kelp and one time with ful-power

I made a tea with WCs and high phos seabird guano a couple of weeks ago.

Using rain water, ph to 6ish half the time, some times I didnt bother

I ordered some earth juice microblast, and thinking about mixing some tap water in

the tops of the plants are still healthy at this point but the nastiness seems to be progressing upward with one plant in particular having theses light spots on the lower fans

Have you looked for bugs, like thrips or mites? Also post pics without the led/hps on will make it easier to find a solution if people can see the actual color of your leaves. good luck

Thanks for the reply. Haven't seen any signs of pests but I've got some neem oil on the way. pic as requested...





I flushed them all, one gal of straight rain water initially (at ph 6.5) and tested run off.

All plants (except two hempy buckets) run off was 7 - 7.5 so I put another few gals each of 5.0 through.

Hempys were like 4.5 run off so pumped some 7.0 through em.

maybe my ful-power foliar was too hot?

did you spray with the lights on?

yup, humbolt sticky, alaska kelp and ful-power

Don't spay with the lights on. Make sure the plants are dry before turning them on. Hid lights will burn holes in the plants if you have water droplets on them.
