Weird stuff happening, weird leaves while other are top shape

I need some help figuring out what is going on...

RDWC
starting 3rd week
Temp: 79
RH: 60-62
Co2: 1300
PPM (500 scale): 300-350
PH: 5.9
Current culture nutrients


I have some plants that are looking like 001 and 002 and few others are like 003... I'm not too sure...

Is it a nut lock? nut def? Over-cococal vs base nuts?

Thanks for input!

I'd say you're way too low on the PPM. I see several deficiencies, including Phosphorus, Magnesium and Nitrogen.

The thing is... I've never been able to go past 450 even in the middle of flowering... so I'm really puzzled.
I'll give a shot at raising ppm and see how it goes.. Would you pump the coco cal a bit vs nutrients base?

Maybe the environmental conditions are too high... I mean, great amount of light, plenty of co2. Could it be than the plant can't drink enough water to process light/co2, giving her not enough food to help the photosynthesis, so to speak?

I'm also running another system, same ph/ppm and everything is fine... (running 2 differents systems), same room so same conditions.
And few plants in the same one (as the picture) are going very well...

I raised the ppm about 50% more. Will see tomorrow how they reacted!

Seems they are gaining a little bit of green but still dropping... But 75% are fine... Weird... I'll bump again ppm 25-35% more and see how it goes...

005 have been doing great since the beginning.. 006, seems they start to recover but still... weird vs the other. ppm is now at 400.
