First time grower with SILS on micro grow

Olders and epsom salts

Olders and epsom salts

Hi guys
So after following caio sugestion i keep my girls a bit further, but i didnt see improvements.
I remember a lot of growers saying that they needed to change some quantitys of nutrients because what they demand under SILS and i think ive been getting the same problem with MG that others have had, thats leads them chasing calmag, N and K when the problem is MG
Taking that in consideration and what caio said about the temps, i went and search again before i purchase anything.
Regarding temps, for example explosive did a tremendous grow with marshydro led at temps around 24/25 the entire grow +/- but those lights have ir wich influences the leafs temp. Ir i have in the halogen bulb, dunno if its the right ammount of power to led ratio but its there but i increased the temps to 26c, and the exctration fan is now on max, it was on 50%.
I bought epsom salts and gave the older girls 1.5l of water ph'd to 6.5/6.6 with just half a gram of epsom.
They drink it all and i just get a few drops of runoff, i watered them 2 days ago with 500ml of water, the day before also and the day before that i watered them 1.5l of water also, they drink a lot of water for just one day without watering so im watering to low on ammount of water i think, im going to start to give them 1.5l of water every 2 days, the soil its peat with perlite btw and i think woth a bit more patience it could get a bit more.
Also i know i "shouldn't" foliar them in flower, but i also foliar them with a tiny bit of epsom and aloe exctrat
Its not noticeable in the pics, but under the leds the leafs are quite "pale" just not in the veins where its still green, also very mate, not that "glossy" but that could be strain dependant since my skunk has that gloss
The younger straped

Her small buddy bud in the "cannopy"

The older unstraped

Also, when i smell the buds they almost have no smell and i dont smell weed either and no trichs for now, no sugar , i only get any smell from them when i rub my fingers in the stems

Day 25 Auto Blue Amnesia xxl

Day 25 Auto Blue Amnesia xxl

I upped my fan exctract because i forgot to turn on the heater and i went to the grow at middle of nights out and the rh was on 80% with 16c, ouch, after 15mnts with the heater on and the exctat on max it was all normal again i just leaved the exctrat the same in full power.
My auto on day 25 suprises me with being taller, praying to the lord Phimax.

Cannopy

Spreaded out for more light directly in the node

Future budsite on side branch(?)

Some of her pubes

I think she is starting to stretch, also dunno if the "jump" in size have something to do with the increased exctration.

My skunk, steady she goes, wider than the auto, but smaller and much slower in maturation growth rate, also receiving less light because of her bigger sister wanting everything for her

In 2 days the new sets that you see in the pic will disapear because i will top her, maybe not 2 days, maybe tomorrow

Both side by side, skunk on the right

Also both of them received the same foliar as her older sisters and i will start to add epsom to their watering schedule too.

Peace

When the leaves start to drop can be:
1 too much light
2 too low rh
3 too high temperature
4 too much fertilizer
5 too much water
6 chronic underwatering
7 too much difference between water and soil temperatures

Doesn't come in mind anything else

I recommend to top your skunk when she is a little bit older...wait she reach the 7th node then top above the 3rd node (the 5 finger leaf) or the 4th node. You can also clone the trimmed top.

Thanks for the suggestion on topping caio

My old droppy girls..the pic is edited to better show what i see in the new growth, that darker green in the veins and paleness on the rest of the leaf..on proper sunlight they dont show with much tho..

Well, i had add the bulbs much more closer than they are now in their younger stage, it didnt bleach them but the fan leafs at the time get huge under the bulb, the readings were in the 50k range, different sils displacement and ammount, now the light is better spreaded and more even.
Also the lowest branches of the trained one seem to be stretching a bit, but the tallest of the both is noth directly under any bulb and displays the same thing.
Thinking logically and since they get worse under the same light intensity that when they were healthy i think its not light.

Could be the watering, since i didnt dialed pretty good yet, for example it was a surprise for me to see them taking 1.5l of water in 10 minutes like nothing, and the rh in these days have been high wich helps the soil maintaining moisture..dunno about that

Soil temp is 20c air temp is vary between 21/24c and i cant take take it up higher without frying the other girls in the other cab but they get heating by IR by the 25w halogen that is there also, so i think that is discarted well as rh.

I talked about MG it because some pics of some guys look like my girls, more in terms of the coloring of the new leafs but that i may be wrong(?)

My bet are in the watering or the lack of MG but i will disconnect 2 lights, the halogen and the 8w that i added a few days back (they were already like this) and see if they say anything, if they dont i will turn off another bulb, if they continue like this i think light is discarted at that point.

Grazie per tutto l'aiuto caio

From the color of the tops seems overwatering.
Magnesium deficency start with the new growth and the leafs more exposed to strong light become more green/yellowish on the leaf edge.

You see in this photo that the plant is hungry and the edges of the new leaves are yellowing and the inner is more green

Epsom is fast acting:
Her 2 days later

You can see that some leaves edges are yellowing yet but she is almost recovered

 

[Caio]

She is her between the two photos

I first give a foliar feed with amino acids and the next day a dose of fertilizer (with epsom) + 2ml/l of fulvic acid as chelant.

Clorophyll is almost an animal heme (the base of hemoglobine):
Amino acid + magnesium ion + energy (ATP)

Heme
Amino acid + iron + ATP

The first 3 chemical reaction to make them are the same for both clorophyll and heme

 

[Caio]

Sorry for the third post....

This can be also iron deficency.

Calcium overfeed can lead to iron, magnesium and potassium deficency

Calmag is for calcium deficency only.

Epsom (magnesium sulphate) for magnesium def.

Potassium sulphate for potassium def.

Iron sulphate or iron chelate (like edta) for iron def.

I can't see very well from the photo but the veins are emerald green?
And the extremity of the fingers green also?
Are the older leafs totally green?

No need to sorry, im happy that you are helping me

Tomorrow i will add one 65k bulb to balance the collours and take a pic, also try to catch some sunlight if the sun comes out..

Im not sure about the extremity of the fingers colors but i think not, i think the green is only in the interveins..

The older fan leafs are long gone, but the oldest fans that are still around, one of it shows the normal green in the middle of the fan, and it gets a lighter green as it gets to the extremitys, but it didnt evolve, but its the only leaf like this. Then there are 2 one in different side branches, that have copper like burn, but didnt progress and they showed it 3/4 days ago i think, tomorrow ill show in the pics.

I turned off the halohen and the 8w to see how they react to the first half of the day shedule..

I dont think my girls are like yours when i compare..
Tomorrow is another day
Thanks caio
Peace

Oldies

Oldies

So after talking with some guys i went to check the pics to see the evolution of them after i added the 25w halogen bulb, between that and maybe too much water i think its it.
Today i didnt turned it on and im gona leave this way, also im going to let the soil dry a bit because i think is a bit too moist

To caio yes they show the green in the veins and extremity of fingers but only on the new growth, under natural light, dont show it much
Natural light

They are not so droopy, but not praying like i would like them to be

The leaf that i said to be with the coper spot is this one

Believe it or not this is my oldest fan lead, it started to get a lighter green a few days ago but didnt progress
This one is one of them that i rub my fingers a lot, also not getting worse and its the only that is like this

Im going to let the soil dry a bit and the next watering is going to be a good feed..

Temps 23/24c rh55/65 cant do it better, night time i dont know so im gambling and i have one silica bag inside the cab that supposely is for a space of 20m2 kkkkk
Sorry for so much text and pics guys, i know im a bit annoying but it will be handy in the next grows..

Day 26

Day 26

My amnesia now is putting good growth, everyday she is taller, i measure in height and i measure the lux as she gets taller, now one 17k lux, i will keep my eye on her to see if she dont start suffering from to much proximity from the lights, 20cm distance now from the 9w sils, less intense than the others in the other cab.
Im feeling very proud and happy, seeing the pics from 5 days ago, she dont looks the same plant, big difference, its beautifull
She is small, not a showwomen but its mine

No natural light pics for her

Temps 25c 50/55 rh, at night the temps drop to 22c and the rh keeps the same

My only question now is if she is puting out some good growth or starting to stretch, im thinking its growth because she is an advertised 75/80 days strain, dunno how much the pot size in volume and height influences that, so taking in consideration the day she is. I think she is putting some growth and will start the stretch stage in one or 2 weeks dunno lets see

Also im very happy with my skunk, she is bigger everyday, not so much in height but in width, the leafs get bigger day by day

Side by side

Peace

Under natural light the color of the tops are total different...
Don't seems anymore iron def...
Can be some zinc lock (too high soil ph) or a temporary lock because the overwatering.
you can make a ph test to the soil:
1 part of soil 2 part distilled/r.o./rain water in a cup ( the cup cleaned with distilled hot water).
Calmag is acidic in water but rise the soil ph over time and peat lose the ph buffer.
And calcium/magnesium nitrate (aka calmag) don't mix very well with other ferilizers.
Next time give it spray (2ml/l) under the leaves.
You can spray it until 3 weeks before the harvest.

Did it exactly like you said and it gives me a ph of 6.7. The last 1.5l watering the ph was on 6.6 and the 3 before that 6.4 +/-
Maybe in the next watering i should be in a lower ph?6.2/6.1?
The soil is pretty wet still

I think all of you guys are right and they are getting to much light but i feel is not the readings but the proximitty to the bulbs..blynx and others use i think 8w 800lm from phillips when they harvest and the plants are about 20cm +/-, mines are 13w and now when i went to check on the soil the higher leafs of the tallest girl are like this

They were not like this yesterday and the only thing i changed was the 25w hallogen bulb that was at the same proximity as the others bulbs, dunno if its a sign they are healing or getting worse, i think worse.

Maybe a combination of factors..

Regarding the lights the only thing i can do is change theyr placemente and put them in the corners of the cab in an angle, thwts the onky way i can get them with more distance.
Im hoing to turn off the only 8w sil that i added 2 days ago and just let the 4 13w as they were before they get worse to see how they react tomorrow.
Thanks caio

 

[Sampas92]

Now that im thinking i can switch from the bulbs ythat are lighting my younger girls keeping the same distance and in the youngers cab i can raise the lights to not burn them..
I need to see how they react tomorrow and then ill decide..
Peace

 

[Sampas92]

My girls under fluerescent lighting for you guys that are more used to it

Also my younger girls
Auto

This one have flash

My skunk

Im really hapy with the youngins, they seem pretty healty for now

Regarding the lighting in my older girls and after looking at my cab i only can do 2 things, changing the bulbs for the 9w and maintain the same distance, or reduce the the ammount of light hours to 18 or 16

Peace

 

[Sampas92]

So 10 minutes before kights out i switched the bulbs
3x 9w 720lm 27k + 1x 8w 800lm 27k + 1x 9w 720lm 65k at a distance ~20cm from the plants, cant get it higher, lux readings on the trained one 22~25k the untrained 15k~27k..

The younger girls i added the 4 13w 1521lm and raised the lights, +/- 35cm from the cannopy of the auto, lux readings in the entire grow at 15~17k

Much more yellow now, dont like so much but what the hell i need to try get my other girls better..
Hope it works
Peace

Don't do nothing for some days with your older plants and see if they recover...probably is only overwatering.

And don't change nothing to your young plants. They are shining.

Reiko is right...we need some LITFA

Well i did it kkkkk
I know i shouldnt make big changes in them but then again, if i fail, i learned something, poor things, they have been suffering for a long time in my hands

And stupid and stubborn as i am, as they recover im going to switch the lights again incrementaly to see how they react.
atleast the trained one seems a bit better, bit more perky, some branches even stretched a bit, besides that all of the buds of the trained one seems a bit bigger day by day, the other seems a bit behind overall, still no smell from both and not any resin that i can see
Or you think i should change everything right away

I need to LIFTA them but i need to see every detail that i can to learn for the future also
Thanks caio

 

[Caio]

Man....i now how hard is take a spoon of LITFA. Trust me. Lol

Your plants seems happy today.
