This is 7weeks from breaking ground...
1-Whole Both..jpg
they growd slowly first weeks but then took off...
i was feeding with tap water of 280ppm and slowly building with nutes truying to give them what they needed without burning them and they reacted well...
last five feedings i used R/O water and was giving them 450ppm of GH
(5ml Micro+5ml Grow+2.5ml Bloom+4mlCalMag) CalMag has a N-P-K rate of 2-0-0..
Temp on the tent is from 71-80 F and R.Humidity ranges from 50%-80% but most of the time is around 60%.
They are under 200W of led cobs.
New Growth slowly started to go Yellow and looks to me like the growth has Slowed Down.
Some leaves on the Dinafem Cheese are showing RUSTY spots
IS THIS SOME KIND OF DEFICIENCY?
DO THEY JUST NEED MORE FOOD?
WHAT WOULD YOU DO GUYS TO GET THEM STRONG AND HEALTHY BEFORE FLIPING TO 12/12
Overall healthier baby Blue Cheese

Probably is CalMag Def...since it appeared after i started using R/O water and i stayed at half strength CalMag thinking that full reccomended dose would be to much...
Anyone has any advice about feeding these babies at this stage???

Hey beppe75.
It wont hurt your plants to give them the full dose of CalMag especially in RO. You can foliar feed them for quicker results too since your not in flower so you could stick with what your doing and add foliar feed at same half portions.
BTW This is Calcium deficiency, CalMag is lumped together by far too many people. They are separate deficiencies treated by the same product.
Good luck with your girls

I'm using hempy buckets with coco on top and grodan chunks in the res... it is my second run with this system.
ph goes in always @ 5.7-6.0 and runoff is good @ 5.5-5.8.

i do hempys too. growstones as the medium. i use RO and 4mL GH cal/mg per gallon and don't have any issues. wonder if the coco is somehow playing a part?

Well...i think coco is playing a part definitely, because i did not have these kind of issues when i was using tap water...even my last grow. anyway today i feed a little bit more of everything and also a full dose of calmag... will let you know how they react...

Update...bongsmilie
This is the situation today....
20160606_024349.jpg

i just fed them 4l each of 660ppm nute solution with 5.75PH...
i thought i would have a little bit more runoff but they were really thirsty.
Anyway the lady on the left gave a 615ppm & 5.95PH runoff
and the lady on the right gave 535ppm & 5.7PH runoff.
Next time i will feed them a day earlier and give them enough water so i get like 30%runoff to get them washed a little bit better with the new solution... is this necessary??? or not???
Temps are perfect...RH also is really good between 55%-75%, there is a lot of air flow on canopy and in the tent...
They look better overall...

This is old damaged leaves...
222.jpg
and since last time i LST-ed a little more and tried some super cropping on some of the branches.

Next i plan to install a scrog cause my first grow i couldn't...or better i installed it late and took it of since they did not stretch past it like i wanted them...
Any Tips or Advice??? Throw everything you got... i need as much opinions as you can...

Thanks everyone.

Sorry @beppe75 if you type @ then someones name they will get alerted to the thread, or if you quote them, I struggle to keep up. Bump up your PH to 6.2 to better absorb micro minerals like Cal

Hey Corey i appreciate your help man...really...thank u.
i fed them yesterday...700ppm @ 5.75PH...
overall they look better...but i just feel they are not at 100%. anyway this is my second grow so i have a lot to learn yet. i'm trying to figure out how i can scrog them and let them get a little bit stronger so they can produce some good quality medicine... everyone's help is really appreciated man.
here is how they look today...20160609_001316.jpg

Cheers:weed:

why scrog? you have a nice even canopy. flip to 12/12 and watch em take off.

do you water daily in your hempys? i played around with mine with multi feedings vs single feedings. i think once a day with about 25% runoff seems to be fine.

Well ... i just wanted to try :bigjoint:.... actually i've done a lot of lst-ing work with them that's why the canopy is so even....:blsmoke:
but i thought that scroging would help them better... last time, i tried to scrog but installed to late and they didn't strech like i wanted them through the screen...so i left them just like they were with some lst work and they turned out fine...
you think i don't need to scrog??? would you let them grow a little e bit more before flip...or just flip them immediately?

i had to read back thru to see your light. 200 w of cob? i'd flip now.
Click to expand...
Why is that?
This is only my veg light...
soon i'll add another 200w of 2 cobs for flower and then some other 4 smaller CXB to reach all the canopy and to have more light intensity and of the right spectrum...
what do you think???
This is a link of my setup...

i think it is a decent one...i have yet to see its full potential.
Guys here on RIU helped me build it....they knew their thing.:clap:

well, you didn't let me know you were adding more light.

still flower now. they'll double in height and you'll have wal to wall buds. those cobs won't go more than 18" deep imo.
