Noob in need of advice please

[krug]

Thanks for your advice guys although I've gotten admit some of it went over my head and I had to go and research what you were on about.
So I have watered her today and upped the 1 ml of old timers plant magic bloom Npk of 3 5 4 to 2 ml per litre which I hope will help some.
I think my run off ph is low but hard to tell as I only had some hot tub check strips to use.
If anyone could recommend what to use that's available to purchase in the uk I'll definitely look into purchasing it.
The same with cal mag as it doesn't seem readily available from what I can see.

Cheers dudes

Found this for you... http://www.growell.co.uk/grow-room-tools/measuring-tools/accuread-ph-meter.html

...Hope these help
I use ol Timers and have often stopped the `grow ferts` early. I tend to split my grow/bloom for a 3-4 feeds(instead of switching straight to bloom), then move to `bloom` only for the last 4-5 weeks (I don`t grow under lights atm though, so feed much less, compared to an tent grow...), average length of full grow(for me) is approx 13-16 weeks

Hey , I use the same product for cal mag (Plant Magic Magne Cal +) as Krug , and sometimes the recommended dose is not enough, so you need to "feel it".
It will take few grows but it is good, I almost want to say it all depends of the plant size ....

And the price is really good on that site. Last time I believe I payed over 16£ for 500ml bottle . I add that shop to my bookmarks for the future purchase.

I actually add lime to my original medium. I find most common brands of multipurpose come with a 5.5-6.0pH. Even though my tap water is 7.2-7.4, when I feed, the pH can go below where I want it. So I add the Garden lime to keep it up nearer 7. Then my Ol Timers brings it back down to 6.4-6.8(depending on `terroir` and weather! If I was growing under lights, then I would be using the CalMag f`sure(from about week 4 onwards, depending on strain/lighting etc)! I agree that if you Know y`ladies, then the `feeling method` is the way forward...but the KISS method is a good way t`start(and continue! )

Wow, brother what coincidence, I use dolomite lime too and for very same reason. I mixed it about 3 table spoons of it, for 10l airpots.
Hey I am running an experiment at the moment, tell me what you think......
I have mixed in to my soil , right on the bottom layer a 1/4 of bannana for extra phosphorus later in the bloom and worked it into the soil like just squishing it and mixing it by hand like working pasta or something.
So far so good, I am on day 40 and my plants are doing very well, was it good idea or it is going to kick me in the balls later in full bloom....?

Well, tbh...I really wouldn`t know! I use molasses in my lil` window pot(a brill addition to any grow imo!), but have t`say that I`ve never really thought about that particular amendment...I reckon that due to m`self not having control of pests(I grow with sunlight atm), it`d worry me(ants/bugs etc):smoking: I have no idea if the nutrients in fresh Banana are broken down enough to be used effectively by the plant and/or microherd(if tlo). So, basically...Y`got me!

Well, looks like time will tell, but I really hope for fat ones at the end .
I red someware about the very old Indian method of growing and it was going like this.....
They used to dig a hole, then used either fish, bannana or egg and place it on the very bottom of it.
They covered it up with the soil prior planting, and basically didn't give a damn . And the plants apparently grew like mad...
Well there is no turning back now....

Skip-- Most of what I see is N defc., as mention by others,... the fert's are pretty mild, and so demand as the plant has gotten bigger is passing what going in it seems,...too early for this much yellowing! What's the NPK of the Old Timers grow nute's? To take some demand off the fans, you should get a blend of grow and bloom going for a few rounds,... also, do you have a stronger PK bloom booster? If not, pick some up,... don't worry about the N messing with blooming, I'm not talking about bombing her with N, and with a booster, the PK values will keep the bloom train chugging meantime,... N is needed all the time, as it's a primary building block for many things, it just doesn't get top billing during bloom....Like Red said, it might have been too soon to switch, but not by much, and likely, you'd still have this problem down the road; my understanding is that annuals like cannabis can store a large part of the N they need even before they bloom, but if supplies were low during veg, that may not be the case here, hence the early fan tapping,... let us know those NPK#'s, and about the bloom booster,.... meantime, keep using the Ca-Mg stuff, as demand at this stage is high,... lime sources are best used as a mix-in before planting; after the fact, it's impossible to get it distributed with any depth, and none are right-now fast acting, especially dolomite; it's a form of Ca and Mg carbonates that constructed differently at the molecular level, and as such is the slowest acting of all,... upside is, it can't raise your soil pH above 7.0,... your best solution to pH measuring is an in-soil probe, like Accurate 8 ... the run-off method is dubious at best, and compounded with low resolution testing stuff like drops/strips, any reading you get is suspect, beyond just too alkaline/acidic,...
