Hi guys,

Small problem with both of my plants: seems the top is turning pale green. Is it light bleaching? Moved up the lights yesterday.
Médium : soil
Lights : 150w led, 20cm to plant moves 35cm away. Ordered new grow room for more headroom (1,7m).
Lst training.
Grow space : 0,6x0,6x1,4m
3rd day flowering, had 4 weeks veg
pH always checked before watering, using bionizz nutes.
Bleaching right?

edit : northern Iights strain

thanks a lot!

Those don't look bleached, but your lights were definitely too close, IMO. Even though LEDs don't put off a lot of heat, putting them too close can still cause bleaching. I personally try to keep my LED lights at least 18" from the canopy.

Are you referring to the new growth at the tops that's a lighter shade of green?

If so, that's normal, it will darken up in a week.

It dos look like you have a mag deficiency. Some of the bigger fan leaves just under the new growth has yellowing but the veins are still dark green. I'm no scientist and I don't know much about growing by any means, but pretty sure they need Mag and N to get that nice green color. If it were me I'd keep doing what you're doing and just sprinkle some Epsom in with your next few feeds

Ordered some calmag.
Should I expect the leaves to darken if that was the problem?B8FC9C44-BFA8-43A6-88FD-A649938EEA8A.jpegE386B818-5C01-4B7C-834E-DAE6DE57DA69.jpeg

no do not "flush" Thats bad and will not help at all.
Do not try to correct perfection. that coloring is a good thing , its showing you how fast she is growing. This is all normal after the flip.
In a few days those will be dark but there will be more new growth , light green.
