Plants getting worse pleases help

[Kush T]

Yeah 17c is cool for night temps.. The raidiator won't hurt that's for sure..

I'd still be upping that feed tho.. Those girls are flowering.. Burning resources inside like crazy.. Shifting elements left right & centre.. It's up to you to provide the sustenance.. I've used fish mix & bio bloom recently.. Both at full strength & it still wasn't enough.

Remember these arn't chem salts your working with here.. It's fish emulsion & sugar beet extract... So to burn the shit outta your plants you gotta go pretty hard.. You're on min strength.. Those plants need some more.

Good luck :Sharing One:

Hey Spooky, sorry to see ya back mate,... I think the guys are onto something with the mildness of feeds and the cool temps,... I forget Spooky, did I tell you hit them with something that has micronute' metals-- Fe, Mn, Cu, Zn... in it? This is usually a specialized supplement, like Ca-Mg.... this overall color fade and severity at the top also smacks of some immobile nute' lacking, or blocked by pH lockout, and/or cool temps, which seems to mess with the absorption of the more poorly mobile nutrients,... Fe is really pissy about neutral-to-alkaline pH, so yes, get that pH down some, even in the water alone,... try 1 tsp/gal at a time of distilled white vinegar, or like brother Kush' suggested, lemon juice, to adjust water/nute' soln. pH... give it a few minutes after each addition, to let it react some and stabilize,.... Oh, forgot to ask, what's your water source? If it's tap, or something with some hardness to it (about 150ppm), that's good... RO/DI water has no hardness, and therefore no pH buffering capacity ...Adding pH adjusters to RO/DI alone will have the pH swinging wildly and unstably!
...Yeah, I see how the more shaded areas look better,... could be because they are under less metabolic stress due to the lessened light intensity, and so the defc. doesn't progress there as rapidly.....

Thanks for helping out again waira u did say to get some cal/mg or blackstrap molasses So Used some epsom salts and got some molasses today and will be using it in the morning how much should I up my feed and how much should I drop the ph? Iv got some ph down should I use this or lemon ? iv got stronger nutes npk 12.12.36 also I'm using tap water .

...epsoms will cover the Mg, molasses Ca and Mg, and a little Fe,...1T/gal
...feed at full strength, on the bottle..Biobizz is very mild, if I recall correctly... try what Kush suggested for pH, and use the pH Down
...save the heavt K ferts until the last few weeks of bloom.... good on the tap water..assuming you let the chlorine gas off!

Yes i let my water sit for a least 24 hours starting to think maybe its Fe or S is looked out due to my ph being over 6.5 if its S adding more cal would be bad would it not ? Also how would I lower the soil ph ? I have some soil which I did not add any lime too so the ph is abot 5.8 should I dress the pots with it ?

 

[Waira]

...S is fine under alkaline condition, Fe is the opposite....even in soil, 7.0 is dicey for Fe availability,...
...without an actual direct soil pH reading, and this late in your grow, and from what info you gave, I hesitate to mess with soil adjustments now,...lowering your feed pH a bit as mentioned should be enough,... try what is suggested here,..it'll take a few days for things to get in there and acting,...I wouldn't expect a reversal of symptoms, so much as a halt to their progression...
...that acidic soil, 5.8, is bad news! Get some dolomite in there and let it sit and react for a couple weeks, then test again,... I highly recommend getting a soil pH probe, Accurate 8 is about the best option, and a fine unit... :Cheers:

Don't use chem pH down what ever you do friend.. You will destroy your micro herd.. Use straight lemon juice to bring your feed pH down...

Stick with the bio bizz.. Just go 3ml then 4ml then even 5ml per L with both bottles.. Are you in the States or Europe? If your in the States get yourself some CaMg+ from General Hydroponics/organics.. Even if your in Europe you can get it on eBay but it's sent from the States.. Cost me more to get it sent here than to actually buy it.. But it's organic has a 0-0-0 NPK & well I swear by it.. Go get it.. Cannabis loves her CaMg+... Lol.

It's strange.. My tap water is around 6.5 to 7.0 pH, When I mix my bio bizz fish & bloom etc my feed pH ends up at 5.2-5.3... I pour that in just as is.. No probs.. I don't understand how your feed pH ends up at 7.1 after mixing the same nutes..
I know our water source is different.. But adding bio bizz feed to your water should bring it way down below 7.1..

Got me scratching my head that's for sure..

Hey kush T after adding nuts my ph is 6.8 my tap water is 7.4 but go's up to 7.8 after its been sat for awhile 7.1 was run off when I watered plain water no nutes which was still at 7.4 hope that clears that up for going to give them a good feed now thanks for your advise fingers crossed it works out

 

[Kush T]

Ok bro.. So your soil pH isn't ridiculously out of range.. Still too high like..
You'll find the pH of your feed will drop more the more bio bizz you add.. This is a good thing.. Go 3ml per L & see what the pH is at that..

How far into flower are you? Sorry.. Autos.. How old is she/are they?

Thanks again kush T there 45 days old
