More nutrients

[Bigoz5114]

Currently in veg phase with a little over a week to go before I will turn. Been having lower leaves yellowing and the plant canobolising them, ph is good, temperature was slightly off but have since rectified and is good also.

Running isn grow a+b, NutriBoost, bloom Silica, bloom roots and bloom calmag, all doses at 100% with ppm around 1300.

No tip burn or anything to suggest under feeding but still have canobolisation issues.

My question is should I up my a+b to maybe another 1/4 dose and see what happens?

 

[Barney86]

You in soil or coco mate? Post a pic and well see whats happening
Also you said ph was good. What is it?

 

[Bigoz5114]

Running in coco mate, ph is 6.2

 

[Barney86]

Im gonna take a stab in the dark and say youre letting them dry out between waterings?
If you are then go read the link in my sig. First page covers it all.
If youre feeding to run off every day then ill go look out my thinking cap.

 

[Bigoz5114]

Yes mate one day a week is dry every Sunday. First time for doing it this run aswell.

Feeding twice a day to run off every time also. Thanks for that will check it out now

 

[Barney86]

Yeah i thought so mate. Wet dry cycles are for soil growers. Coco doesnt react well to it. Take 10 mins to go read that link bud and ill answer any questions if youre still unsure. I made it as easy to understand as i could

 

[Barney86]

Probably some environmental stuff going on too but sort the feed out first and theyll sort themselves out in a few days as long as the roots havent knackered from being too dry. Bit of a coin toss that one actually. Should be sound. Youll know by this time tomorrow

 

[Bigoz5114]

Righto I’ll knock that off then.

My perlite mix is 70/30 aswell plus the few additives you’ve mentioned obviously I’m using also.

So correct me if I’m wrong, if I keep upping a+b 1/4 dose until I get too burn I will be safe?

 

[Bigoz5114]

Yeah I’ve sorted out my temperatures, normally pretty consistent and spot in but normally running 6 and have only 2 this time so has thrown me haha

 

[Bigoz5114]

I also run from a resivoir

 

[Bigoz5114]

Awesome write up by the way mate

 

[Barney86]

Thanks buddy
Id cut the nutes in half and just start feeding them every day. 500-600ppm should do them. Run a good few gallons of it through them over the next couple days though. The coco will be shot to shit with high salt build ups and ph will be knackered so it needs reset. That's what's causing your yellowing, not actually a lack of nutes.

If you've got reservoirs you can rig up an auto feed system for about 20 quid and never have to feed them again. Run off runs back into it and gets reused so almost no waste.
check the res every few days to make sure it's balanced. Easy. Means you'd be able to use the ppm meter to tell you how strong to feed them too

 

[Barney86]

Oh and no lol. Don't up it till they burn. Other way round mate. Only up it if things go yellow. Much easier to add something in than it is to get something out.
Which you might see over the next few days. They'll be sound in a week though so just keep feeding them week nutes at high volumes and they'll be good.

 

[Bigoz5114]

Running twice a day currently automatically on timer with a pump in the resi using feed rings and getting 20ish % runoff per feed As I do run to waste.

Check resi every day when I’m in there and always stays consistent, have and airstone and 500lph pump in there keeping the food moving.

The strain I’m doing currently (excalibur) is a hardy strain and can take slot but still a bit puzzled about the yellowing and canobolisation of the leaves as I feel I’ve diagnosed everything else

Wait a minute mate I've just lost myself here. I'm so confused. What you mean you're watering once a week but also twice a day? That's just melted my brain man. I never spotted that the first time and I'm really just so confused now lol.

 

[Emilya Green]

also check that pH. Adjusting your incoming pH to 6.2 is not helping your plants at all. 5.8 is much more appropriate in coco.

 

[PE636]

I think he must be watering twice daily every day except for Sunday? I agree with @Emilya ,I'd have gone with a lower ph in veg, I think that might be the issue especially if you are there constantly since the start.. Also what kind of water are you using?

 

[Barney86]

Ahhh I get it now. Fuck me I need to stop smoking so much in the mornings. Had nothing but bubble hash the last few weeks and it's wild. Can actually feel my brain cells popping lol.

 

[Barney86]

Ah yeah and you said at the start they were on 1300ppm but now say they been on 500 anyway? God this stuffs too strong like. Help me out emilya and think I've cracked haha
