Help coco coir transplant shock/fluence 2i

I would bump your temps up a couple of F too.

He is nervous to introduce the Fluence lights again.

But now he has a dimmer.

Yeah I start with 200 ppm calmag and nutes like 700ppm the first few feeds to the coco can lock up whatever it wants then I drop to 150ppm calmag and 500 nutes and slowly raise it till tips burn. People say you can't overwater but I think thats if you're watering 5x a day till roots are established. I just water every 3 or so days until roots are established and then everyday and 2x per day when they start packing on bud

It’s been 2-3 days. My whole rooms has greened back up.
What I did when I noticed stress

pulled the fluence right out of the picture and replaced with 1 315 cmh per 4x4 ( still not fully ideal but it’s enough)

upped my CaMg from 3.75 ml ish right Up to 6 ml/ gal.

dropped my 3x daily fertigate on back to 1x ( seems like there right around the corner from deffinately needing 2x)

and !

tomorow I am Introducing the fluence at 10 percent and working up from there. And praying.

At the end of the day shitty coco that wasn’t treated correctly by the manufacturer or myself before planting. It was stealing my calcium.

I’ll post pictures today or tomorow when I have time it’s going to be a beautiful room!

my run off ph has been low but I’m trying to ignore it at this point going in at 6.3. My range was 5.5-5.9 I’m pushing thatup as well...... 5.8-6.3

Right on thanks for the insight!

I see very very mild signsalmost the good kinds of heat stress going onin the room now..... but what your saying is pushing em even warmer to maximize photo & co2? What’s the limit in regards to temps in veg w/ supplement co2?

Honestly couldn't give you the figures on ideal for co2 , but generally you get better transpiration over 80f without it and as im aware the use of co2 usually calls for higher than normal temps I figure your a bit low with or without co2.

Going on my own experience with LED in veg I know it was the biggest factor in keeping plants happy and when keeping temps up was difficult in the dead of winter the next major factor was to reduce light hours (obviously veg period) these things made the world of difference in plant looking happy and uptaking nutrients.

first 3 photos are my 4x8 same strain same coco everything the same expect there in 5 gallon containers.
under 2 electric sky v2 300 true watt fixtures at full strength. There doings really well. There’s temps are runninghigh 70s low 80s.W/ out co2.

The other photos are today after a slight Defol/ lollipop pop ( plan to flip Monday)

today is day 3 w/ fluence at 20% 3 ft or so off canopy still with the metal halides 315 hanging underneatheach fluence.

Something is still not quite right. I’ve got 36 plants and I’m going to have to do some individual tests( sucks because the room is maxed basically wall to wall .

I think somethings off with my transpiration and vpd but when I reference that chart It seems I’m good runnings low 80s f 60 70 percent rh.

feeding 1.6 ec right now w 1/4 strength pro tech silica flora flex 1/1 ..... .6 is CaMg .....

also my run off ph ( I ignored mostly last cycle with no problem pulled just under gram /watt) has been low 5.4 is the lowest I’ve seen on a table to table basis the other 3 not far off at 5.5 5.6.
