One acapulco gold under 2 veros 29

Hi Guys...
After so many years of reading...and reading ....and reading it's time to make my first led grow
tend: 70x70x170 made with kouvidis heavy type electrical tube 25 mm
led's: 1 bridgelux vero 29 4000k 80cri and 1 2700k 90 cri
drivers:2 mean well lpf 90d 42 with one dimming pot 100k +10k resistor each
2 cpu heat sinks with fans running at 12v and for thermal paste i use prolimatech pro-pk3
AC is now 23 days old i use only the 4000k 18/6. At the end of this week i will transplant her to a bigger pot and i will add and the 2700k led .yesterday i feed her for first time with 0.4 gr/l of miller nutrient express 18-18-18 maybe i was i bit late...at the last picture we can clearly see a tiny problem with the leaves...i have no mites.maybe is hungry or i need to add a cal mag solution(miller have 0.50%mg but i don't know if it is enough)room temp 26-29 Celsius max, water ph 6.8 ,humidity 55%i know i have to raise it a bit...
the becks of automatic watering i used it only twice because i left for 2 days and i won't use them again
i know i'm better DIYer than grower but i don't care if i don't have the best results next time could be better....
Any thoughts will be helpful

i forgot something very important...a big big "thanks" to all of you guys for helping me with the led 's

Congrats on your first build... The plant needs a bit of magnesium, for example epsom salt or Kieseriet.

Cool, keep this going.

I was just about about to write something similar! It definitely needs magnesium. At the current stage of growth it could go either way. If corrected now the plant will recover and yield well. If not...well not so good. I use Epsom salts @1tsp/gal. I just dissolve it in small amount of hot water and mix it with a gallon of diluted and ready to use nutes. I've also had a good response by foliar feeding using the same concentration but just diluted with water.

thanks for the advise i order Epsom salts i will have them on Friday

I'm watching you! Very intersted in one/two COB grows...

next update tomorrow i would like to see gr/w in one plant to use the hole space and light for one plant...most people here calculating gr/w with 4-5-6 plants...maybe is better i really don't know and i would like to see that my self.the only think that makes my a bit unhappy is that the Epsom salts will be late for 1 day more

so...
today i feed her with 0.4/l miller 18-18-18 and 1/2 tsb /lit epsom salts...i'm happy because despite mg def i have a good fast veg maybe my nutes help for that but for better results will find out the next days....

Yep - nutes are those which gives a boost...
Give more little, by litle, hehe )

To me, she looks good!

You will scrog/lst her?

i have enough space to do something with her . but i don't know what .. next week i will transplant her and for sure i will make topping

If you want to train mainline her you will get the best yield and it's very easy to do.

wow very nice topping method but if i understand well i have to leave her much more time at veg state for stem constriction and the time pressure's me a bit.
but truly very nice training method

How long do you veg now? You can get away with a 1 month veg with clones.

currently 29 days i'm not planning to make clones at this grow

like

How come? You can make a small clone/veg box out of a Rubbermaid and leds for $50 and never worry about seeds again us it's a faster veg time.

I'd like to see how the lights go (good so far) but also the AG, not a hydro grower anymore but my most recent vanilla kush looked just like that. A few shots of epsom salts will help. May have slowed her down a bit.

I only grow part year so (its clones in or) seed whore der these days too

yesterday i gave her 1/2 tbs in 1 liter of water i'm waiting for results

vegging for 32 days yesterday i gave her 0.6gr/lit 18-18-18 plus+1/2 tee spoon epsom salts
and today i transplanted to a much bigger pot .the medium is 50% perlite 30%black peat 20%humus ...my mag deficiency i think that it's stop.the newer leaves look healthy but i don't think that the older leaves will recover..i will let them for 3 days with water only and i will top it at the 2nd node with some lst

one day after transplanting the plant looks nice no stress at all so if tomorrow still looks ok i will make the topping/lst . i gave her only water to be easier to make lst
