Blueberry OG leaf issues persist

Need some help guys & gals…these plants have shown discoloration in leaves since their first set of true leaves. Whatever it is, its relentless…i keep having to pull more and more leaves.

Aero/hydro
Water temp currently 67.6. Floraflex nutes. Starting e.c. this week was 1.86. Current e.c 1.75. Ph 5.88

This issue has existed since before they were even being fed. It started in straight R.O. when they were seedlings, but its gotten worse.

Any ideas?



Can you show me the roots?

And by Floraflex, do you mean … Veg 1 & 2, Bloom 1 & 2, and… or…? I just need more info to be able to steer you anywhere.

It looks like a phosphorus deficiency that’s pretty advanced, but I’ll preface that with Im not an expert at all.

Also water ph? Other things used on what schedule?

Couod this be a zinc issue? If you zoom in on the pic of the 2 plants, it kinda has the same pattern as the leaf disgnosing chart that gets passed around



Yes the veg a/b etc…so far thats all theyve gotten, in addition to the veg foliar spray which i completely forgot about until 2 days ago, but i sprayed them that day.

Today they start week 2…for week 1 it was supposed to be 2.4 e.c. but i underdid it bc i was worried about the 2 younger ones. The final solution was 1.86.

This week (todays batch) is supposed to be 2.7, but it just measured at 2.58, which im thinking should be ok.

I just posted todays pics of them in this thread so you can see progression. I removed the worst leaves a couple days ago.

Ph has been between 5.5 and 6 the entire week. Nute temps between 65 & 68.

Bout to add the week 2 new nutes, just waiting for the gallon jugs to warm up. They were at 55 degrees when i brought them home today. Nutes mixed in amd ready to go now tho

Edit: forgot to mention that the majority of the roots are in the net cup. I started them in my aerogarden, and i left them in too long, so i kimda had to swirl the roots around like noodle, to get them to fit in the cup.

Also, just thought id mention again, this issue has been present since before their first feeding

Yeah - I’m thinking this strain may just be hungrier for phosphorus than your average weed. In hydro we have that unique disadvantage of almost inherently beginning with the deficiency and working our way up to what a plant is comfortable with, instead of the reverse in soil - since dirt holds nutes and eventually they get consumed.

I would perhaps add a 1/2 dose of the Bloom Part 2 to the res along with the rest of your regularly scheduled nutes. That should help her out.

PS - the new growth looks good. I wouldn’t stress the rest of your nutrient schedule, it should be on point. The extra Bloom part 2 is just to chase away the (I’m fairly confident) Phosphorus hunger.

Thank you so much! Going to add 1/2 dose bloom part 2 now! I want to try this strain so freaking bad and ive been worried i was going to lose them. Thanks again!

Keep me posted. Just remember the old damage won’t go away, but hopefully we keep it from progressing into new growth. :v:

Definitely. Ill update in my grow thread and include you when ive noticed a change (hopefully)

Before i do…according to the feeding chart, it has week 1 bloom starting at 5 grams, wk 2 4.5, wk 3 4 grams, etc…should i go with half of week 1?

I think that should be okay. I haven’t really ever noticed my plants give me beef about too much P or K. They seem to mind nitrogen, but the other two I can push pretty hard.

Ok thanks again. Its definitely got to be something with this strain…the pic of the small one by itself, in the purple collar is the strain i grew last time, and while it has a little brown on the edge, it is not showing issues throughout the leaves like the other plants…

In fact, i have another one of that same strain in my aerogarden that i never changed the water out from when they were on their seedling dose (i did today finally), and its growing like crazy lol its been flourishing in 2 week old mildly dosed water with no temp control

Its really been interesting seeing just how much varience there can be from strain to strain. I thought maybe the genetics were bad up until your post lol

Also let me plug floraflex again for sendi g me the full tilt starter kit when i asked for a sample. Its enough for 1.25 - 1.5 full grows…fully on their dime, fertilizer wise. Ppl working there are so nice and friendly, too.

Yeah, I find every strain to be different but none so different I can’t get the res into a happy place for them. My newest round of flowers wanted way more CalMag than the prior batch. Like way more.

I’m going on 2 months now I think without a reservoir change and my ladies don’t care. Once the root zone is happy, the only thing to watch out for is to make sure salts don’t get the chance to build up.

Very interesting…did not know we could go that long between changes. Im going to stick with weekly until im more expercienced, but nice knowing ive got a lot of room to work with.

Im guessing you either use or have used floraflex? Do you go with any additives? I was thinking if voodoo juice, from when i used AN last grow. Those roots were massive and healthy all grow. Although for all i know, they would have been either way, considering it was my first grow lol

Yeah, I tried weekly changes and as far as I’m concerned it caused more problems than just leaving it alone. But I am also a lazy grower so it may have been entirely my own doing.

No, but I specialize in tracking down nutrients and finding their breakdowns/ingredients. FloraFlex in general looks low on P compared to Jack’s and others. It looks well balanced and like a stellar base nutrient. Just like you may need a small Arsenal of supplemental nutes (like a monopotassium phosphate for bloom time to help encourage the flower time growth) to get the really picky strains in line.

Generally I use Silica Boost, Tribus/Fish sh!t, molasses, and monopotassium phosphate (branded MOAB/Mother of all Blooms) as my additives. I keep CalMag on hand because the Epsom in Jack’s doesn’t seem to sate some of my real picky ladies.

Were you factoring in the full tilt and bulky b when you checked over their line? I hope not bc i was hoping to avoid a lot of supplements lol

I add about 3 ml of AN cal mag to every gallon of ro before adding the floraflex, bc they suggest getting the water to .2 to .3 ec for proper ph balancing. The AN one comes with nitrogen though so i may look for another one.

Ill check out those others you mentioned. Thanks!

Everything in the pic they sent me…veg a/b, bloom a/b, full tilt, bulky b, and veg/bloom foliar. All powder.

I just checked against what was included in the sample pack, because I sort of assume that’s how most growers go when they’re trying a line of nutes for the first time. So I only factored V1, V2, B1 and B2.

I can’t figure out what Bulky B would be good for. It’s a weird nute ratio. The Full Tilt is the equivalent of my MKP (MOAB). So I think you can skip the MKP

Edit: yeah, check out Silica Boost. It’s cheap from Amazon and is a truly good silica. No N involved.

Ok thanks man. What is the silica for? Does it replace voodoo juice or the cal mag?

Im gonna try just using what they gave me plus something like voodoo that has the living stuff inside it and the cal mag and silica depending on what it is

Silica provides structure for your plants. Helps support the weight of the buds.

Voodoo juice is just microbes (like tribus or fishsh!t)
