Dutch Passion 4xABBs in a scrog under a GN MS0006 rebel

[steelrat]

Hey DB, can't believe i haven't stopped by for a month! Sorry. i'm crap

Those girls are W A Y hungry for N !!

You've made the mistake of going up and down with your nute levels, you should be consistent. Day 28 you were giving them 2ml/L, shoulda been 3ml/L.

Always best to push the nutes as hard as you can since it's a lot easier for plants to recover from slight overnuting than it is for them to recover from slight undernuting, in my experience.

This is my first ABB grow and i am finding them to be medium-feeders, not light.

Get some N in there !

Next grow try the dolomite lime, too, but use more than i did since i now realise i didn't put enough.

I used one slightly heaped desert spoon of dolomite lime powder per 3L, i think next time i'll use twice that, and also prepare the soil a month before planting, as i've read on gardening websites that it takes a while to combine with the soil and spread it's helpful stuff.

Don't forget, in terms of nutes, too much is better than too little


All the best,

steely

Looks like Andy Beat me to it. But not to worry i agree with what the lads are saying. She is under fed especially if that isnt tip burn your have.
I guess it makes sense what steely says and its the most logical conclusion, You bumped up your feeds one day and went down the next while you were trying get everything all dialed in. This cause's serious problems with the plants as sometime they are hungry and want that amount of feed again but dont get it causing them to react in this way. Sorry i didnt notice this sooner,Something i should have copped on to as i have done this myself in the past. I was giving the complete opposite advice just to be safe and im sorry for that dude.
Hope she picks up for you now man, things are looking good.

Thanks for all the feedback guys! It's very much appreciated. It seems the general consensus is underfeeding so I'll be sure to up the feed next time

She does look like she is in need of some CalMag, don't be scared of it, it's pretty difficult to over do it with the stuff, and if you do she will be very dark green. I'm unsure of your manufacture dosage but mine is 2ml/l (full) I mix in 5L bottles so 10ml, and I feed this from seedling to flush, my plants seem to have a lovely dark waxy shine to them, and I'll only get a def when I back of the stuff.

The biggest part to play I believe is not your nutes or ph, that's all spot on mate. It's because your growing with LED, I believe the rebels are better when it comes it CalMag, but you still have to keep it up. I would best suggest to keep feeding CalMag and watch closely for I movement.

Let your pots dry out completely, and give them a small feed, something that will only last the day, then feed again the next day. Fresh nute per feed should clear it all up.
:gthumb:

Thanks Mr Kip, thats's good to know, I'll keep that in mind for the next grow. I will up the cal-mag next feed and try to feed it daily with a smaller amount of water.

See the link in my signature. :Sharing One:

Thanks for the link mate!

Looks underfed to me.

Thanks for popping by Tang!

Agree with TaNg. From the start of this grow you've been super careful with not overfeeding and I think you've actually gone and underfed them all slightly all along the way. Next time definitely up the feed from the beginning esp with cal-mag. Switch the bloom nutes earlier and up the nute strength a bit too. If you're worried about nute lockout or over feeding you can flush them every 3-4 weeks out of safety. Add more perlite to your next grow and feed little but often. More regular smaller feedings as Mr Kip says will help and upping the perlite content to about 50% will let you do that no problem.

Seems like those Rebel lights really love their food. Which is a good thing because if you do it right, next time you could have big bud.

You're right Happy, I've been feeding them the same way I did under CFL, that's obviously not enough. I ordered some perlite already, I will pick it up tomorrow.

No worries steely, it's easy to lose track of threads. I will definitely use dolomite lime next time. I will probably start the next grow around the end of April so if I prepare the soil now it should be fine. I think I will go for 2 tablespoons of dolomite lime per 6.5l pot together with 2l of perlite.
The reason I went down with the bloom nutes is that I was worried they would be getting too much N since the cal-mag also contains 2% N and I've been using that at 1.5 times the full dose., which is equal to 2ml/l. I figured 1ml/l of bloom at 3% N together with 2ml/l of 2% N would be equivalent to 2.33ml/l of a nute with 3% N, which is nearly 1/2 dose as far as N is concerened. I thought that would be enough in flower, I was obviously wrong
Next feed I'm thinking something like 2/5 of bloom, double dose cal-mag and a full dose of PK.

No worries Briain, I appreciate your advice. Next grow I will have a better idea of what they need and I'll try to be more consitent with the nutes. I will be growing photos next time though, not sure how much that changes things. I'm hoping it will recover somewhat and if it doesn't, the other plants are in decent shape so it's not a complete loss.

Day 40

Plants are in decent shape all things considered. I spotted what I think might be a P-deficiency so I switched them over to bloom nutes last watering, see pic below. Last feeding consisted of a 1/2 dose of bloom nutes and 1.5 times full dose of cal-mag. Next feeding I think I will add some PK as well. I think I will be watering every 3 days from now on as they looked a bit droopy after 4 days.

I haven't seen any Mg def on the new leaves so far, I hope it will stay that way.

I think this is a P-deficiency, please correct me if I'm wrong.

ABB#2 starting to bud up.

Hey, check out my Sugar Mango in my sig. I have had the same problem with all my plants. With me it was bad PH and not enough nutes. I'm growing organic, soil.
My plants are improving now.

Hope it works out,

Karma for your grow man.

looks like you are getting good advice, good luck with the rest of it bro

Wow, my eyes hurt reading all that! Are you feeding using the nute manufacturers schedule? I use Biobizz and follow their schedule, it's working a treat. Suppose the guys who make this stuff no best. Worth a thought anyway.

Good luck!

I use plant magic magne cal+ You can get it easily in the UK.
http://www.plant-magic.co.uk/products/magnecalplus.html

It does have a bit of NPK in it as well as Calcium Magnesium Iron and a couple of trace elements too. I've found it works really well.

Plant Magic - Magne-Cal+ recommended dosage for Soil/Coco: 0.5ml-1ml/Litre
Plant Magic - Magne-Cal+ recommended dosage for Hydroponics: 1ml-2ml/Litre (important - mix thoroughly before switching the pumps on!)
Plant Magic - Magne-Cal+ NPK: 2.55 - 0.11 - 0.33
Plant Magic - Magne-Cal+ Calcium content: 3.54% (as 4.96% Calcium Oxide CaO)
Plant Magic - Magne-Cal+ Magnesium content: 1.55% (as 2.58% Magnesium Oxide MgO)
Plant Magic - Magne-Cal+ Iron content: 0.0424%
Plant Magic - Magne-Cal+ Molybdenum content: 0.0011%
Plant Magic - Magne-Cal+ Zinc content: 0.0073%

Also like Steely says too much is better than too little. At least with too much generally the leaves go dark green, claw downwards, then start to burn around the edges. You can back off by giving them a bit of a cleanse with plain pH'd water with a little run off and see if they recover. 2/5 nutes sounds too low too me. I'd do full strength cal mag and half strength base nutes and build it up bit by bit until they give signs it's too much. Once every 3-4 weeks do a clean water cleanse, then hit them with slightly stronger nutes again.

Thanks Tony, I made a bit of a mess of this grow, I hope the next one goes better. I'm really looking forward to growing and trying out the CBD kush. I figured I would throw in the photo variety of the Blueberry as well. I'm curious to see how it compares to the auto.

Hehe, sorry about that. There is a feed schedule that I've been following but it doesn't contain any cal-mag so I wasn't sure how to deal with that. I had a look through your Super mango thread as well, nice!

I like your proposal. I will be feeding them today with 1/2 bloom nutes, 4/5 of PK and a full dose of cal-mag.

Day 58

Quick update, half dose of bloom nutes was not enough to stop the progression on ABB#3 as it kept yellowing, it's in pretty bad shape now but still alive. Last feed, 2 days ago, I upped the nutes to 4/5 of bloom and PK, and a full dose of cal-mag except for ABB#1, which only got 3/5 as it's pretty small and has a dark green color already. That seems to have stopped further yellowing on #3. Ironically #1 suffered the worst initially but is now looking better than the others. I'm guessing since it's smaller it doesn't need as much nutes.
Compared to my last grow under CFL I'm now feeding with twice the amount of nutes.

This is one of the leaves on ABB#2. I see this slight yellow tint on a lot of the leaves on #2 and#4. It's been two days since the feeding and I haven't seen any signs of nute burn and I'm wondering if I should up it to full dose bloom nutes next time?

Hi DB, i see no pictures in that update ?


All the best,
