Help, still suffering issues with my HBSS. New nutes

[awolace]

So I'm still struggling with this grow. Ive never had these issues with previous nutes but this is my first round with the old timer range. I always fed the same way with biobizz or chem nutes without issues. I posted a thread last week in which I thought I had N Def and corrected however there are still problems. I feed 1ml old timer grow, 3ml old timer bloom, 1ml topmax, 0.75ml pk 13/14 and 1ml calmag per litre. Don't ph as mostly organic.

Looks like phosphorous and nitrogen deficiencies to me however with what I'm feeding I would have thought enough was going in.

Anyone have experience with old timer nutes. I really wanted to use them but have found similar posts with the same issues and am tempted to move back to biobizz?

Hi there. Im no expert in diagnosing, Cal Mag issue maybe ?
However your plant is that close to the finish line i wouldnt let it bother you. Looks like you have done a great job.

check your runoff PH...ive had similar issues and my soil was down at like 4.8

Im questioning the old timer nutes ive got as well now though...ive run into PH problems with them every grow...flushed my last set of autos at week 4/5 and they didnt have any issues but ive just done a run of photos and they ran into really bad PH problems a few days ago...

do you water to runoff? i also dont think my water supply helps...its pretty hard!

Hey bud! ...mmm, she's snacking hard on those fans, no doubt! You're right about the N and P defc. symptoms, good eye mate- ... good news is, I don't see any other sign of other defc.'s, or badly off-pH,... and she is really blooming thick for buds this age, so serious demand is going down here! - I know, it seems like you haven't done a thing, but imagine what she'd look like if you held back,...
... tell me the NPK on the old Timer nutes, and let's have a look at total NPK inputs first,.. likely it's just up'ing and tweaking the regime a bit, and of course, some of this fan tapping is normal as well, no stopping it,...

Cheers for the input waira. Old timer grow is 5-3-3 and bloom is 3-5-4. My last feed was 5ml bloom plus 1ml pk boost giving total NPK of 15-38-34 per litre. As you say I don't think it's ph related, she may just be hungry. Is there a possibility she may be getting root bound? She's in a 5g airpot.

... It's the ratios and dosage conc. that I needed- Thanks! Seems a pretty hearty feeding- - don't sweat the N part, some is normal at this stage anyway, and her color tells me there's plenty stored, I think she's after more P-K; try upping that to 3ml/L... At 5gal, root bound to the point of being an issue, likely not....
