Couple of Questions to shake off the rust

Hi hows it going, this is my first grow in awhile, I probably have about 5 harvest under my belt(all with 400 watt setup in telephone booth like space,ebb & flow & soil)but now I have my first bigger setup, 2 1000's,charcoal filter,wall a/c unit in a 5 ft wide 9ft long 6'6 ft high space w/ (a drip system eventually)for now I'm watering by hand.I keep the temp between 73-78 degrees, I want to get a humidifier so i can have the humidity on lock, but it generally stays between 53-63, Im a little new to the digital TDS meter and measuring your ppm in water, even though I had a ebb & flow before I was "very" young and inexperianced, I remember just using the back of the label on nutirents to guess kinda -lol...now I understand much better, but probably could still use some help...I was kinda using this chart for reference about PPM levels https://www.greenpassion.org/index.p...399-ppm-chart/

I just started the clones this past Monday(10pm-4pm), I have 12 bunched under one light(3 gallon pots) right now while there in veggie and when flowering starts Ill split them off under the 2 lights.

-I use a RO filter,Sunshine soiless mix as medium,(nutrients I use are) CNS Grow,Ripe & Bloom w/ Liquid Karma and Cal Mag. The Light started off at 36 inches and i worked my way down to about 21-23 inches over the course of the week. I started them off w/ a pretty low PPM at about 275 and 300 for the first and second day. then shot up to about 475 the third cause I just had a feeling they could take it(hope that wasn't a mistake) and were ready.(all the water given had a PH of about 6.5-6.6)

They seemed to respond well to the higher dosage(leafs perky, new growth already showing very green) so i stuck pretty close to that dosage for the next 2 days(500 & 510) and they still seem to be doing pretty good...there just not as green as i would like...almost seem a yellow shade but still green paleish...i only water them once when the lights turn on, and the soiless medium holds water very very well...maybe too well?

So basically Im just asking for general advice, Ill try and get some pictures up here soon, so you can see what im talking about...Since there still in the first week of VEG, Im going to lower the PPM in there water to about 350 for 2 days to see how they react...

Im also going to post how much of the nutrient solution i used for each day so feel free to chime in on that if you see something wrong

Day 1 & Day 2
1/2 tsp liquid karma
1/2 tsp cal mag
1 tsp grow

Day 3
tsp cal mag
2 tsp grow
1 tsp liquid karma

Day 4 & day 5
1 tsp cal mag
2 tsp grow
1 1/2 tsp liquid karma

Thanks

...the funny thing is that the one i took a close up picture of is the one i was worried about...but after looking at it through the picture it looks perfectly healthy!! ...my mind is playing tricks on me i think?

So I'm just going to continue to give them around 500-550 ppm for the next 4-5 days...then ill bump up to 550-600 for a week....then 600-700 for the final two weeks...Sound about right?

I guess ill just keep the grow log going, hopefully I don't have any probems but if i do it be nice to have some green helping hands.

well got some leaf curl(upwards goddammit -lol) did some research and I think I over ferted them...i found a much better PPM chart that breaks it down by day...and i am going to stick to that one http://hugeharvest.com/feedingschedule.pdf

since Im still a newb with the TDS IF someone....ANYONE!!!! could please let me know if this feeding chart is right...

I would really Appreciate it
HELP ME OUT!!!... & good Karma is coming your way

rule of thumb for me was 1/4 of what it said on feeding chart & work your way up to full strength. i tried never to go over 1600 ppm. do a flush with ph'd water & try again

ok, should i use ph'd RO water for flushing? or should I just use regular ph'd water?...I have a flushing solution too...it says to use 1-2 TSP per gallon so Im going to put in 1/4th of a TSP in every gallon.

Also i was giving them about 550 PPM so im going to cut it to 250 or so and work up tp 350 over the course of the week...but my question is this...

when I add cal mag to RO water it has ppm of about 200 per tsp
the Liquid Karma is generaally low in ppm ranging from 50-150
and the grow has the highest where half a tsp can range from 100-150

So should I use a the full tsp of cal mag always no matter what? then add the other to get to my ppm amount? or should i use less cal mag...say 1/2 tsp?


Also one thing i forgot to mention was I have a vortex 650 Cfm fan for exhaust(my room only needs about 350, i figure w/ charcoal filter and lengthy air ducting its about right)and i dont use a intake fan as the suction from exhaust is very good...and I have a fan blowing right under light & over plants plus one other fan for general movement in room
