Hello everyone, I'm new at this forum and also a newbie at growing. Due to a lack of knowledge about plants, I ignored the symptoms and couldn't catch early action, I hope it's not too late.

It's my first grow and i chose Tang's easy schedule,

Soil : Plagron Light mix 

Nutrients : AN sensi bloom A,B - Voodoo Juice - Carboload - Overdrive - Guanokalong Extract.

They are at 15L pots and 38th days.

I was using A,B since day 10. Days 10-20 (A,B + Voodoo). Started Carboload since day 30.

I was confused about deficiency or toxicity and both girls have flushed 2 days ago and spots on left are increasing to the top leaves.

I don't know what to do next, please help.

@euphoricpython This seems like a lot of food to be using in a soil grow TBH. 

How much are you using of each? Like how many ML per Litre of what food?

@euphoricpython AN are usually ph perfect so its not a major issue if you havent been checking pH, but i think 2ml of a n b per litre is a bit much, 1.5 was probably enough. I have never used carbo load, and not sure what it is for, usually big bud is used at this stage. Has the problems here started since you started using carbo load?

@macky I was encouraged to do this system because of the PH perfect yes, thank you for suggest. Problems has started before carboload but increased dramatically after carboload. By the way, left one is lst'd and right one is not. 1.5 for the left one or right one? What should i do

From what I can see it looks like a calcium deficiency, although it could be a lockout. What's the soil pH like? Dud you check the runoff at when you flushed?

@bubblehok  I didn't check it unfortunately and also don't have a ph meter.

I'm leaning towards too much food creating lockout. There's a good bit of clawing on some plants and definitely some deficiency in the cal/mag spectrum. Are you feeding every time or are you alternating between feed and just water?

I would recommend a heavy, heavy flush with cal mag or something similiar to help bind the nutrients and get them out of the soil.   This looks exactly like what happened to me initially with my tangie.  Flush fixed it.

@shonuff Thank you, bro. The spots are spreading to the newest leaves of buds of the left plant but not right. Is the problem the same with two girls? Do I need to flush them again or just the left one?

Yer, most soil growers alternate between feed and just water if they are using bottled nutrients. It helps avoid a buildup of excess nutrients in the media. Shonuff hit it right on. A good flush is the first step.

When in doubt, flush and start over.  That is my new motto after all of the bullshit I have put myself through.   😄

When you flush it needs to be a lot of water washed through the medium, and if you can I highly recommend a soil ph test kit at the very least to get a gauge on what the soil is doing. That link @monkeydo dropped will walk you through it if you haven't done it before. Just make sure you Ph your water on the final flush you pump through the medium, and with soil and salt based nutes you rarely need to use the full strength they recommend, it is almost always too much and will result in lockouts.

You are not missing that I have flushed them right? If not, how much calmag do I need to add to my flush water? 

Thank you guys, by the way, this is my first grow and I'm dealing too much shit so I'm a bit fucked up and overthinking about it. I guess I need to flush my head too Grin

@euphoricpython can’t help much with the plants but the lads will see you right i’m sure. 

I remember getting real down when my first plants got sick, you’ve invested money and it seems like it’s all going wrong and your going to fail. You’ll get there man honestly. Each time improving and you’ll save yourself a fortune in the long run 

 

Chin up 😀

Yes, if it is still spreading you should flush again and like Bubblehok said, ensure you get alot of runoff to ensure things are washed out thoroughly.   I use 1 teaspoon per gallon of cal mag when I flush.  But that is in Coco.  I'm not entirely sure if you are growing in soil.   Once you flush, go half strength with your feed.    I'm also fairly new but this is what I did and it saved my plants!  Good luck and God speed!

So with flushing this is why you really need a ph test kit or ph pen, you need to flush till the run off or soil is back within normal ph range. In coco we flush alot of water usually up to three times the amount of medium until the run off is reading the desired ph range. In soil I would suggest running the flush until your soil readings are back with range not so much the runoff. One of the soil guys will have a better idea as to how much that takes but either way it's a lot of water needed to get it back down or up to desired ph. After you get the ph back in range, then you want to mix up a very light dose of nutrients, I suggest 1/4 dose or Max 1/2 dose with added cal mag and then feed till run off is achieved. Then slowly increase your feed and keep an eye on the soils ph. The leaves that are already affected won't usually recover but the new growth should return as normal and the plant will start to get back on track. Don't be disheartened it happens to the best of us and just takes a bit of time to correct. Shouldn't take you long though. One of the soil lads may have a better insight into their methods of flushing but usually its basically the same idea, only dwc or rdwc systems are really different, but even then the idea is the same. Hope that helps mate.

In soil the only time I actually flushed was quite a while back that was because the plants were burning.

i followed the 3x amount of water compared to the the pot size.

so if there in 10l pots that’s 30l of water.

it cleared it up but the plants were floppy at first..

@mix yeah coco being coco holds less moisture as there is far less peat and usually a lot of perlite to help with drainage, soil tends to be alot more peat heavy and will hold the moisture longer so you are naturally going to see a bit of water induced wilt happening. When I do outdoor runs after a real heavy rain they wilt like crazy, an hour later they perk back up lol

Guys, thank you for your all sincere thoughts and advice. And I could honestly say that I'm at the right place to learn and share. I will update the situation after the flush and feed.
