here is a picture of what they look like just before lights out today(7am) the plants looked decent 8 hours earlier.. they seem to be still a bit droopy at lights on (1 pm) and then get better and last night at 9pm they looked decent ..
been running just ro water and some cal mag additives las two watering in the promix when i did run off the ph was 7 and ppm was 600ish
then just before lights out TRASH.. been watering with the water at a 5.8 ph for the las two cycles
i use a humidity controller 50-55
temps in tents are under 30
hydro res under 20.. house is set to 19 during day and 18.5 at night these are in basement.. never had this issue before with last grows this seems weird as all get out ..
have outdoor plants running same nutrients and they are fine ..
and here is pics at 4 hours into lights on today .. those crappy photos were from this morning 20 minutes before lights out
no watering in the soil and nothing to res .. gonna add some ro today as there has been some evaporation with my swamp cooler so just to bring the ppm down a bit
It's not abnormal to see plants droop a bit before light out. They get used to a light cycle and will often look like they are getting ready for bed.
Looking at the info I think they are just being driven a bit hard for thier age, conditions and light cycle. I would back the light off a bit more and increase the humidity.
A par of 300-400 should be good with an 18hr light cycle. Where we need to increase this to your 700-800ish is in flower. This is because we have less time to deliver the light.
Plants have a light saturation point and this is largely affected by CO2 levels. Without CO2 supplementation on an 18hr light cycle 300-400 should be plenty.

ok .. i’ll back off light for sure .. charging up the par meter now .. used to run last batch at this level no issue and no droop :) the clones in the small tent are young but the others are months old from seed been mainlining

Could be more light sensitive strains. I just ran into that myself. Make sure there is not constant airflow on them or it can lead to windburn. Instead of tossing a Rh number at ya I will link you a thread on VPD. In high light grows it makes a big difference especially in hydro.
Ok i was gonna sit down and write out a whole article but i have been lazy so instead instead I'm going to copy paste because im lazy. This is not my work so let start. You may find this very long but its worth the read. Some may want to skip ahead. I have added here and there to what i feel is...
