I Stumbled Upon Something WAY Better than Tomato Cages. Highly Recommended! \(^. ^)

Overall they actually look like they're mostly green all over! How many leaves are showing symptoms? The main thing to me is the leaves look dark green and the edges are curled down, like the plant needs overall lower levels of nutrients (specifically Nitrogen). How much water are you giving at a time? I also think you could maximize your yields if you added a little more light especially to the developing buds! You've got so many bud sites, but it looks like many of them are relatively far away from a light. It looks early in flowering development, so there's lots of time for those buds to fatten up!

Haha, that's awesome to hear you say that. Well two of the girls are still relatively green I must admit, and the other two not so much.

On Daphne, i'd say at least 80% of the leaves are showing severe symptoms. The other girl doesn't have so many leaves left, but i'd say 50% of her remaining leaves are problematic.
I'm watering twice a week, usually giving each girl 3 litres of water. For the last two weeks i've completely cut out ALL nutrients except calmag+, as well as some unsulphered molasses.

You know what, I actually decided to buy a proper HPS grow light two weeks ago, and merrily drove down to the ONLY grow shop in this country with grow lights. And to my absolute dismay, he is completely out of stock on reflectors. He has ballasts and bulbs, but no reflectors. He say another month until he receives a new shipment.
He also has no LEDs on sale, although he said MAYBE he might get a shipment this next week.
It's kinda sad, cause I really wanted to up the light levels. So far I have a total of 855 watts in my grow room, but it's clear (just as you say) that these girls want more light.
