As a new grower I've learned "flush that shit" fix's a lot. But doesn't teach me what I did wrong. It's just different approaches to teaching growing. Being a noob, I like Dr's simple fix because it's overwhelming trying to learn everything at once. If I was smarter, I would roll with pop22. Hats off to both of you !

You will learn .

 

[Dr LSD]

True. We both know our own kinda shit. Take what you want from whoever. That is how we all learnt. I never trust any cunt, and to fixate on an idea, requires trust. You can fix your feed or start again. That's totally your choice and dependant on your grow style. But sometimes i have no idea what i did wrong. And flushing gives me the ability to prevent further damage if i am guessing at the problem.

 

[Dr LSD]

If you misdiagnose... what if you exasibate the problem. Flushing is like turning the machine off and on again. And if you paid for the food and the company still exists, that's unlikely to be the problem. Just don't feed as hard as they recommend to sell thier product. Peace

If you are organic and want to learn how soil really works... you are smarter than me. I tried it for 15 years and still don't understand what the fuck beyond what works for me. Soil is a complicated science. For me it is interesting but hard

 

[Dr LSD]

And i meet coco. It's not as involved, and you tend to leave the science to the geeks. I use it in every organic garden now, just to get more air to the roots. I used to love perlite, but now i throw waste coco everywhere. But anything to bring oxygen to your roots. It has nothing to do with your issue. But don't get to bogged in your soil. Roots need air so much. Air is what makes roots take off!

 

[Dr LSD]

There are so many ways to do it and all work. But a flush has always worked for me when i fuck up... so much so i have my flushes on a timer. And i always see better growth after the timer and my plants are fed just water. And it is the most common mistake i see. Your roots suck up all they need from the nutrients avaliable, then what you have left is a concentration of what the plants did not want to eat. Get rid of that shit completely and feed again. Just my 2 cents. But im drunk and talked way too much

-- what other nutes are you using? I'm not sure that bloom booster has complete coverage of secondary and micronutes in it,... early symptoms either way, not Mg though, wrong symptoms,.. looks more like Ca to me, with the fine spotting along veins,... that water must be quite soft-- naturally I hope, not made by ion exchange units?
I'd start on a Ca-Mg supplement, and look into those nutes for completeness,... other defc.'s may kick in if they are incomplete, micro's in particular!
I think I see some bug damage too (light colored stippling on upper surfaces), likely thrips or something from the leaf hopper clan,... something sap-sucking, larger in size, and highly mobile! I know well as an OD grower myself :smoking:....they are ubiquitous, so if you stay outside, this is a war, not a battle,... plenty of safe bug killers out there, and I also use SNS209, a organic systemic derived from rosemary oil,...makes the juices taste like crap!
Flushing (in true soil) is more of an emergency procedure IMO, unless you're a notorious overfeeder,... true it can serve as a shotgun blast reset, but not knowing the underlying cause does you no service at all, only potential set-up for same errors,.. plus, it's a trauma for the roots as well, basically you're waterboarding them- .. smothering starves them for O2, and depending on how free draining/well "breathing" the soil is, it can cause problems as much as fix them,... personally I use flushing only when the soil pH goes way off for whatever reason, and the usual corrective measures fail to fix things,...

Thanks guys for the many detailed replies. Interesting to read the different solutions and thought processes. Clearly different methods to deal with problems effectively. After reading through the replies, I decided not to flush right now.

I'd already ordered some Cal-mag after reading the initial replies, which had arrived yesterday, so I watered in some of that last night. Will see what happens. Both my plants have both become more fussy since budding kicked in. I feel a bit out of my depth with it now. I find myself looking at everything on the plant simultaneously wondering if I am under or over worrying about certain things. I'm just going to keep going and see what happens, I am sure the yield will be tiny compared to what an experienced grower would get, but if i managed to get ANY smokeable product, I will be really happy, so as long as the plant doesn't die in the next few weeks I'll have achieved that. It's a first grow so I have already learned plenty if I decide to do another. Maybe an indoor one over the winter :smoking:

Thanks once again for all the info- have found this forum to be a great resource (and a friendly one).

@Waira I've been battling bugs for sure. Hoping they have fucked off now. Used some organic bug spray a while go when I caught a family of thrips chilling! Not seen anything on the leaves since, think the damage is from before.

Calcium def never seems to reverse for me, once you get it it seems to remain but it can be slowed. Its not too much to worry about if you chuck some calmag in the mix, you will loose a few sunleaves here and there but its no drama... Always worth having a bottle of calmag and some epsom salts around, for coco, id say its a must have.
