Jock horror (feminised) 6weeks veg under 2x 65w cfl. Currently
10 days into 12/12 and under 600w hps. Temps 65-75. Rh-50-75%. In cocoponics. Using canna cocco a&b with canazym and eventually pk13/14. Ec is currently 1.7. Ph is 5.9.

Sorry for taking the photo with the lights on, not sure if its a bad idea to flick the light on and off just for a photo.

I have had some ups and downs, mostly with temps and humidity... but i had most of that sorted before switching to 12/12. I havent topped, fim'd or anything like that. The main stem is thick, branches are strong.... shade leaves are big and others are fair to medium.... i wish i had lollipopped it because i can see the lower branches will miss out on the lumens further into the grow.... the growth is dense.

I have just misted epsom salts (for magnesium) to see if i can correct a slight yellowing in the leaves.... i have had this before and the epsom salts worked fine, but never during the flowering stage.

RH inside is generally 20% higher than outside the tent. I heat the water to 19C (66f). I have no algae or root issues that i know of.. i flushed it 2 days before switching.

I am noticing that my res PH is increasing slowly; i beleive this means the plant is using more water than nutes, so i might ease of the nutes....

Any questions just ask... will get some more pics up soon. Hopefully with the lights off.

epsom salts are used as a replacement for Calmag, not a nitrogen deficiency which is what you have here. Get a supplement heavy in nitrogen and feed with it 2 weeks into flower.

Hi God, dont mean to doubt you but can we discuss what you just said for a moment.

My understanding is that N lockout is rare in Coco with Canna A&B nutes. Where as Calcium and Magnesium deficiencies are common.

The yellowing is on newer growth and starts from the inner leaf and is interveinal. How can you see the N deficiencies when the pic is so yellow....

Well then post better pictures. I see yellow leaves on the left and right of the plant. If it were a Calmag problem you would have the spotting and gray brown ends.

As I am sure you know, after the flip the plants go through a huge growth spurt. This often causes an N deficiency which is why many growers stick with their veg feeding during the first couple weeks after flipping the lights.

The epsom salt is not a bad idea, since this one is also fairly common after flipping, but I agree with GH, bump up your N a little bit during the stretch.

Edit: Also, not a good idea to quickly cycle your lights, can you not remove the plant from the tent or take a pic right before/after your lights on?

Youre right about interveinal yellowing being an indicator of Mg def. Spraying on Epsom salts mixed with water is the fastest way to get Mg into the plant. There is a product called Magic Green which is mixed and sprayed on leaves also. It is the fastest way to get N into your plant.

Thanks, the epsom salts have corrected the yellowing but i will take the advice on nitrogen and bump it up some.... Plant looks amazing now but so much growth im wondering if i vegged to long....

Im gonna get some pics up today hopefully just before lights on... So you can see what i mean.... The new growth looks a bit 'weak' and not like the other growth which is robust.

Ok... First thing, i apologised straight up for the picture. The yellow you see on each side of the pic is because of the HPS. What i wanted to know was did i need to trim it. I never said anything about "calmag" - only mg being a problem. I have since rectified with Mg and am going to take your advice on the N, but c'mon man its so obvious that the yellowing on the sides is due to the light coverage....

so ...

Cal = C = Calcium = Dolomite Lime (among others)
Mag = Mg = Magnesium = Epsom Salts (among others)

i dont have a calcium deficiency, of that i am sure...

With that shitty of a picture, taken while your HPS is on, no it's not obvious. But if you have all the answers man, by all means, I won't stand in your way.

Calmag refers to the common supplement, used to treat both Calcium and Magnesium issues. You can buy it cheaper as one product than you can both of those other items.

FIRST: It's not to late to crimp the bitch, half way down so when she lays down, ALL branches receive good light. http://www.420magazine.com/forums/frequently-asked-questions/70032-supercropping-tutorial.html Good info for HOW to crimp....


Second: GOD HERE is correct. Epsom salts will not correct a nitrogen deficiency. You need to increase your nitrogen. You are not LOCKED OUT. you just have a deficiency. http://www.420magazine.com/forums/problems-pests-disease-control/81275-cannabis-plant-pest-problem-solver-pictorial.html
Nitrogen def. in flower... YELLOW. you are not as far in so you will have yellow NEW growth because you are not in full bud. you understand?

This is a magnesium deficiency
you see the difference.. use the second website from now on to help you diagnose yourself.

and use the first to crimp your lady so you can increase her yield ASAP. if you start to FULLY bud (3=4 weeks in) before doing this it will only stunt the plant. but you're 10 days in.


Third: As for pictures..... Quite simple if you stop to think about it... Remove the plant from the tent and take your pictures under different lighting....... This will help you get closer pics for us to see and give you a diagnosis. As of now, you have not posted a picture for us to view. That one is Worthless to us. Sorry...... I'd like to help you out as best as I can as would any grower on RIU. You just need to take in the info given instead of trying to argue a point......

Whoa... Check the last post on page 1 of this thread.... I added two more photo's.... Before you all had a go at me, refer the first photo and you will see the plant in normal light.

As for GOD HERE, dude... I know what calmag is... And i know what the deficiencies look like... I dont have a n deficiency/lockout (again refer the second lot of photos - especially the first). i would have rep'd u for the advice on N but youve just ripped me apart for questioning based on what knowledge i have...not cool, not to mention i apologised for the 'shitty' picture on the original post.

I did have a mg def/lockout - this has since been rectified as per second set of photo's... I took your advice for the N and will probably rep u for it anyway.... I am looking into the crimping now but man... After the second lot of pics im unclined to say the plant is healthy and doing fuckin well for such an early stage....

Again... All the leave are healthy, lower leave are NOT yellowing and new growth now isnt either... I would say more but im on ipad and it sucks typing with it...

Where are the other 3 plants that fit in that grow room :D?

Next grow... This is a personal challenge, this lady has now filled the entire floor space of the tent... So no, no more room now... I know i vegged it for 6 weeks but it had what looked like 8 weeks of growth on it when i switched.... It is a monster, i have only ever grown this strain, This grow is outperforming the first two by far...


but yes, next grow im gonna experiment with scrog or sog, after that im gonna try lst, and the topping over fim.

I'll concede that with one of the new pictures you put up you don't have an N def and it looks like you rectified your Mg issue, but then again, the new growth looks perfectly healthy in that photo so is there an issue or?

The yellowing has subsided, i beleive what ever it is has been fixed. I have lowered my nutes so that my res ph is staying constant at 5.7 - i find the leaves look more...perky after a watering at this ph. I will begin with the PK/13-14 next week so im expecting some explosive development from what i have read about it.... although i struggle to understand why i can only use it for a week.

I am continuing to look into crimping, but i fear i might stunt the growth too much....

Initially my question was regarding trimming her, my HPS is now sitting 30" from the coco surface... the plant is reaching up and the further away i move it the less lumens are gonna get through to the under growth - however, i beleive it is now to late to trim so im just gonna go with the flow and see what happens - where needed i will tie her but other than that she is free to do as she pleases.

SO i guess at this point there are no issues..... that i can see.... except; -------It's not ready to smoke......!

Definitely move the HPS closer if you have a fan. I keep mine 8-12 inches above the plant; it helps the beef up the buds and keeps it from having stretch issues during veg. But I also bend mine over with LST, so if you're growing straight up it might still stretch a bit.

yeah... the hps is 30" from the coco surface... but only about 10" from the top of the plant... so i think it ok where it is for now.... but im worried that the 'stretch' is gonna push it far enough that it does become an issue... i am considering "crimping" as per advice from SxlStew, but im not confident... and i also set out not to trim/prune or fuck with the plant in anyway when i started - but as i said... so much growth might force me to do exactly that. My next few grows... will be experimental as is this one.... i am going to try as many different techniques as purely as i can. This grow is to set a benchmark - 6weeks veg, 8 weeks flower - 2x65wCFL / 600wHPS in cocco100% with all canna nutes and supplementing def's/lockouts where needed.

I have taken your advice and raised my 20cm oscillating fan, now it blows directly accros the top of the canopy between the hps and main cola... i should be able to squeeze some time out of that and hopefully the stretch doesnt continue much longer... i still have a smaller fan circulating around the undergrowth.
