Leaves pale green - Biobizz

Hey everyone,

Trying BioBizz nutrients and growing organic for the first time.

On day 24 of flower and have noticed the plants are turning a lime green colour on the tops.

Everything was perfect until I changed from my MH to my HPS then it started going a lighter green on the tops. Below the top of the canopy is a nice deep green. There are no spots or marks on the leaves, just pale green.

The odd leaf is yellowing and dropping off right at the bottom but not significant loss, presumed it was due to lack of light getting down there.

Just after some thoughts on what people think is happening and whether it's a problem or not?

Ph is 6.5, temps are 27c in day, 20c at night. Watering every 3 days with 3ml bloom, 1ml grow per litre.

Thanks in advance!

yeah its probably the hps being too close .. they can be extremely bright
it lead to some kind of deficiency starting from the top (bleaching)
put it farther

Thanks Kingromano, I backed the lights off as soon as I noticed about 7 days ago. They don't seem to have got worse.

Will these leaves recover to a healthy green again or are they now permanently damaged and will stay the same pale green colour?

Thanks

no the damaged parts will always be yellowed .. but plants will continue to grow over it so depending on the damages it will partially dispapear
its ok i think
