HELP! Overnuting or undernuting?! *PICS* (High-res)

Hey community, whats good

Little rundown. First time hydro grow (bubbleponics system.) One res change, about a week ago now I was ill informed and I think did a large overnuting. Changed the res about 3 days after I was informed that I was using way too many nutes. Prior to that, my plants were lacking in micro nutes (long story) and the pH was very unstable.

About 4 days ago, did a res change added a small amount of micro, grow, and bloom thinking it may have been an overnute. Since then, leaves have progessively gotten darker green and some dark grey shades. Some of the younger leaves have recently gotten these orange spots and weird discoloration (shown in pics) as well as the dark green.

Now, it has been a week since the overnuting and I am not even sure if the nutes had much time to set in before I changed out the res, but things are not improving so I thought i'd post it here and see if any of you all know what might be goin on. Thanks much!!

For those that don't want to read the whole mini-novel above. I THINK I may have added too much nitrogen, and that is leading to many micronute deficiencies. Or I am not adding enough now? I am afraid to add any more nutes cause I am not sure whether it is undernute or overnute. There are many leaf tips and edges that are burnt, some are curling under like a taco, some dark spots, some orange spots. Not affecting every plant in the same ways. Fungus?

Growing in hydro bubbleponics. pH = 5.8-6.2 . Res temps 65-70F. Air temps 70-75F. Using flora series nutes, GH ph up/down. PPM's only 780ish right now

looks like the beginning of a mag def

yup you got some nute burn, flush em

nute burn seriously..ive never had nute burn that looks like that..even mild case..my mag def..starts out like that white the white spots then turns to yellow brown spots

just fush your res and put in some fresh nutes

just get some fresh water and dump it through the roots, when you flush it with fresh water the nutrients the plant has stored will release into the fresh water, then dump it out and do it again, just had the same problem and it worked for me. I have the same nutes but my res is a 5 gallon bucket

imo this doesnt look like nute burn, its gotta be a def, prob mag

You need to use more micro and less bloom..hardly any..www.progressive-growth.com
for a feed chart.

Sweet, thanks for the replies. I knew that I used too many nutes but I switched them out so quick I didn't think the plant had time to store any of em. I'm guessin the overnute is causing mag and maybe some other traces to be locked up. I have never really "flushed" per say, done a lotta draining and replenishing.

So, to flush out all the extra nutes I would just drain waht's in there now, add 6 more gallons, drain that, and maybe pour a liter or so of water thru each rockwool cube to flush out any nutes in the RW and roots? Then of course refill w/ pH correct water, but at this point do I add nutes or do I just let it sit in fresh water for a few days?

Appreciate the responses just not too sure how to flush if anyone could let me in on the proper way for hydro. I'll check that site out too purp. Peace/love

just rinse off the roots to get the old nutes out..Ill let mine sit in the bathtub for a minute moving the roots around under the water and then put back in the BP..continue with normal feeding schedule.

Appreciate it Purp. I'll flush it out the res and the roots and hope for some improvement. Peace

Shitttt.... they are REALLY looking bad now!! I did a full flush, dipped the roots in fresh water and soaked em for a min and put them back in. Put 9 ml/gal of micro nutes, 2.5 ml/gal of bloom, and only small amount of grow cause I thought it was nitrogen overnute before... about 12ml of grow all together.

I am really starting to panic now, about 2 hours later the bottom leaves on one plant were wilting and turning REALLY brown and it is spreading up the plant now w/ rust spots and weird coloring!! Ahhh..... PLEASE HELP ME!! Even my perfect plant before is getting spots on it now too!

Here are pics, what did I do wrong???! How can I fix it?!!?

sorry I needed to vent this out. I used half tap water (180ppm), and half distilled water. Is that a problem?? I let the water sit out for like 15min before putting in res, the tap water that is. Please help me out... wow they are deteriorating QUICK! THANK YOU ALL please I need to save these babies!

Also, the pH started out kind of high and is high right now like 6.8 but I am battling it back down and it isn't rising a whole lot quickly, just started out high cause I used half tap water I think. But 6.8 pH would not be causing the plants to die this quick... ahh.



If you look closely you can see white areas in between the green as well as the orange spots which are easy to spot.



Man they were looking MUCH better prior to the flushing, what happened?? Should I have NOT added nutes for a few days or what? Is there a deficiency? I am sooo confused right now.

use some vitamin b or superthrive

First thing's first before i get started check the plants everywhere for spidermites.The reason that i say this is the yellowing speckles can be caused by these little [email protected] cleaning out the resiviours make sure that you scrub the hell out of the inside of the tubs use a thick stem brush.When growing in the way that you are always keep the ph tester close to hand because it will chnage afew time through the grow.The leaves been dark green is a good sign this normaly means that the ppm and ph are ok it is when the leaves look light there is a problem.But in whole honesty bro the plants don't look that bad at all seen alot worse alot worse belive me.Just make sure that you give the resiviour a good scrub when changeing nutrients.But you should recive a nice yeild from these plants i would guess but the ppm is around 11 hundred so they will be fine.Stick to the ph all the way through the grow from been young right up to the flowering stage then my ph is not far of this will avoid large ph flucktuation so try and stick to the same ph.I only grow greenhouse strains and the perfect ph for them is 5.0/5.5 so this is what they get start to finish.But i do flush once aweek and test runs offs.But i understand this would be a realy pain for you has i grow in soil.I use a old school nft constant film of water grow to get my plants from clones up to just over a foot but only by a couple of ince.Make sure that you check the ph on the main tub.If times tubs all hold water then keep a ph testing kit with ph up and down at hand all the time.By doing this you can check a couple of times a week and add whats needed if it is.Make sure that the clones/seedlings are kept on a good feed clone's recive nothing other than ph of 5.0/5.5 with drop of multithrive to every ltr of water.After the first seven days then add a product called plant start don't over do it just give the clone's a gentle tug if there is resistance then they can recive plant start.If the clones pull out easy then if you have enoughth get rid,Spray the leaves on the plant with the superthrive but not the plant start ph are same on both.Good luck keep green tyke.

to what amount of water did you add these nutes?
Are you running a drain to waste or recirculating?
here this will help for veggin..

I wiped off some of the brown salt buildup from the nutes i'm guessing on the sides of the res. Added 3 gals of distilled water. Mixed up bout 56 ml of micro into a half gal container of tap water. Added that to the tank. Added 15ml of bloom and bout 12ml of grow to another half gal of tap water. Added that to the tank. Topped it off to the 6 gal line with tap water.

Drain to waste or recirculating? Not sure what you mean by that... just using the bubbleponics w/o the feeder tubes now but I leave the water pump on for water circulation. I use the drain plug to drain.

Thanks for the grow chart. Where should I be startin now with nutes? I just don't know where to start cause my plants have been so weird lately, it is officially almost week 4 now but the first 2 weeks not much happened.

Thanks for responses. Should I just let it sit for a few and see what it does? Should I remove the dead leaves?

Superthrive? Do I need that what does that do?

tyke, there are no spidermites. I know it's not a bug problem I got rid of them earlier on and they haven't shown up again but I did double check the leaves to see and nothing.

Who told you to use both grow and bloom at the same time?

I'm confused... the feeding chart did and if it was diluted I thought it was OK, but I added the micro first on it's own to avoid those problems. I had half a gal of tap water in a container, so I added the liquid flora bloom and grow to the same container with the water in it figuring it would be diluted in a half gal with only about 10ml of each. I have always heard people doing one batch with additives, and one batch with nutes. I almost thought I was making a mistake adding micro first on it's own w/o the other nutes. Is this wrong?? Thank you Roseman.

yo man i saw you were running a water pump all the time for circulation, be careful doing this as it can raise your res tem alot higher than it should be, get an AIR PUMP and aristones, if youre not using drip tubes there is no need for a water pump.
