Skunk #1 Day 28

Started flowering I believe but still have the yellowing issues, added the epsom salts on Thursday and it has got slightly worse. Potted up to an 8" pot on Sunday night, gave first dose of HESI COCO........think it grew an inch overnight. Stands just under
12".



Should i be worried about the yellowing? Like I said Ive added the epsom salts and will continue to add them as per Del's advice..........any advice would be appreciated, I thought I had read a ton about doing this but I feel like I dont know wtf I am doing.

As above, but she is slightly behind the Skunk. Stands at 9"

I don't know that I could have been growing this summer with my previous setup, it's one of the reasons why I went with LEDs. The main reason was fire hazard though, I own my house and I got a little paranoiac about that... I am away from home for days every once in a while and it feels so much better now, I can be at peace when away from home.

Up until April, it had been a hit and miss with LEDs for me, but I was also an inexperienced grower, but I knew I could get some good smoke out of them too. So I took the plunge about 2 months ago and bought a 540Watts FERO led light to replace my 2 400W, the rest of the setup is more or less the same. I got everything ready and I left home for a couple weeks with my woman taking care of the plants, when I came back, MAN! was I ever sold on my new setup, I had never seen my room so green!

One modification I had to do is my air intake now draws air from upstairs in the house instead of from outside. Outside would be great right now but 2 months ago it was getting too cold, and another thing is from using the air from outside with my mh/hps, I couldnt keep the air flowing at night, so my humidity would always spike at night, now the fan is on 24/7, I have better control over the environment. The lights still get fairly hot in the way that you wouldnt want a big LED unit in a small room without good venting, but the plants could accidentally grow almost up to the light without much damage.

I think it covers everything!!

I havnt the cash to invest right now... but after some more reading im interested in LED.... if it would eliminate the damn giant ass hood i have to run to keep my tent cool and get even equal results id be pleased... plus no bulbs to buy and a lot less duct and lets see.... a quieter fan too (cause it wouldnt have to run at the rate it does cause of the ducting.) i see alot of pro's and the only con is the willingness to drop a giant fat wallet on just a light... Gotta ask though, why do i keep reading you have to grow "different" with LED.... yet i have not found anyone who has actually explained the difference.... wtf? any light you can shed would be appreciated

Yeah coco mate, Ive switched them both onto the HESI COCO now, going to up it to 5ml/ ltr on the next feed........I added the epsom salts on Thursday, no change yet.

add epsom each time you feed........prevention is better thats why i start in veg........im sure they will improve in a few days....

 

[UKHomeGrow]

Is the following ok to use as a preventative?

5ml neem oil
1/2 ml insecticidal soap or other detergent
1 liter of warm water

I grow in a shed which is surrounded by trees so bound to get some bugs at some point........I know there is a discussion re this somewhere in this thread.....just cant find it in the 797 pages lol

yeah thats cool.....protection should last a few weeks each time you spray...i do them for a last time around 3 weeks in flower.......i also use 4 aspirin in my 20 litre tub once a week.....crushed to a dust....mixed with boiling water then chuck it in my feed...

I am not sure, I hear something like the plant go through more cal-mag due to the spectrums (I have no idea why) so if you feed with nutes you gotta use it. Also I hear that the plant use half the nutrients with LEDs. One reason why growing with LEDs is different, the soil doesnt dry as fast and I think people get confused with how they should go about feeding, so you don't get to feed the plants as often. It sounds like coco is the way to go if you want to use commercial nutes and LEDs/

I saw a lot of people failing with LEDs with commercial nutes, it seems like a total nightmare sometimes!! I simply kept growing the same way I was with HIDs, using supersoil, growing 12/12 make the whole grow happen so fast that I don't think my plants really have time to show deficiencies. Last batch of supersoil I made (that I will be using this fall), I sprayed a little bit of cal-mag on the pile of soil, but this current run right I didnt use any cal-mag, just plain water and supersoil and it's all good.

If you were to grow with commercial nutes you would have to ask someone like puffenuff on the LED section, he grows in coco with nutes I believe.

Nice, what does the aspirin do? I need like what half an aspirin in 4 litres? That's all I need to mix at the minute.

Man, have just realised that the pots Im using to finish in are only 4.5 litres......thought they were 6. Should I just repot when the roots fill out the pot or change it now?

repot now, you get bigger plants if the roots are free to grow 12/12 from seed

Is your avatar from team fortress?

Lol yeah, someone finally noticed XD

man you plant looks fkin amazing for 250watts!!??

This is about 800watts of LEDs, 7 plants, 1 is ahead of the others, and a couple are quite a bit behind... but everything is 12/12!

Thanks, Nice setup you have! I'll be getting a 600w hps very soon this is just for the time being.

Your plants look healthy to me, a tiny bit of yellowing is normal in some strains. They will darken as they get older. I use epsom too but be careful not to use too much, I usually add it every other feeding just to be safe.

My only advice is topping the plants will help the lower branches receive more light. The sooner the better and the faster they will recover.

 

[Serial Violator]

If i start the plants in a 1L airpot how at what stage should i transplant them in to their final pot? Before or after the start to flower??

 

[UKHomeGrow]

thats whats i figured, going to get some bigger ones today.

Thanks mate, Im going to wait until ive grown at least one plant and got some bud off if it before I start considering topping, fimming etc.........will be nice to smoke my own and not give some arsehole 20 quid for 2 grams of shite.

I have 3 seedlings on the go at the minute also, about 10 days since they popped through the coco, maybe ill top one of those and see how it goes.

 

[majek]

Lol I understand exactly how you feel, but topping is very important when it comes to growing indoors. If you don't, the lower branches will not receive enough light and grow tiny whispy buds that are hardly smokable. I like to top my plants twice, once when they are about a week old from seed, and again when the plant starts to flower. Without topping you will end up with 1 main stalk and a bunch of tiny undergrown branches.

Our goal as indoor growers is to produce as much bud in the smallest space possible, topping is the best way to achieve this. It also helps keep the canopy even and all of the branches get an even amount of light.

an aspirin for every 5 litres...not more or it may burn............keeps bugs away and keeps immune system on full alert....

Nice, will be adding the aspirin moving forward, thanks for the advice.

I hear you mate, just want to get a handle on the whole growing thing, as long as I can get at least an ounce dry from my first few plants Ill be happy. Def going to top one of the seedlings and see how it plays out. Two different Kush strains and white shark.....I think white shark will be losing its head.

Ok good luck You will definately get an ounce if you treat them well. I harvested around 2.5 oz my first grow and I did not treat them so well lol.

just been reading up on topping......at what node do you top for the first time? I read to let them grow out until the 5th node and then cut just above the second, this gives 4 main cola's? looks sweet but im gona crap myself when I get the scissors out lol
