Deficiencies? Help!

[spliffas]

Hello friends. Growing under 600w boost hps. Just finished week 4 of flower (when 12/12 on), tomorrow will be day 29. And it looks like I have some problems with my Delicious black russian:

First lower leaves turned yellow ( I cutted em as I was doing defoliation to most of my plants) and then I noticed ‘sharp’ leaves. I think it is pretty noticable in the photos above. And it seems like this plant grows veryy slow now....


And I have two Delicious Sugar Black Roses (one of them):

Stems turning purple and this one not defolited rose looks yellowing her bottom grow’s leaves too... ideas?


My whole garden:

Now I was giving them nutes somewhat like that onto 10l: 5ml pk boost + ~6.5ml bloom.

I increased dose a little, now I give pk boost 1ml on 1l and sep bloom 1.5ml on 1l.

Any ideas? Maybe cal - mag on russian?

Don’t want to mess things up, so help needed :/ thank u!

Honestly they look fine to me .

It’s normal for def to show up after preflower and yellow leaves as long as not a mass concern of them you can cut off or let die off.

Thanks I may be too paranoid do you consider me giving that larger dose of nutes? That larger would be 0.75 recomended dose.

Yeah but most don’t go over 50 strength for nutes though

Check your ph. It looks like a bad ph imo

 

[spliffas]

Too level ~7.5 going down to Root level ph all pots 6-7

Russian

 

[spliffas]

And water which i feed from tap is 7 ph

 

[KingJoe83]

Try to add ph down last when adding nutes and bring it to about 6.3-6.4

 

[spliffas]

Thanks will try to get some! (Y)

I defoliated rose a little:

Let’s see what happens

 

[spliffas]

Ordered ph down should recieve till next watering, tried experiment with freshly squezed lemon juice on rose and russian, pots are heavy, maybe overwatered a bit, but it should dry quickly I believe... we’ll see...

I think white vinegar too drops ph not 100% without double checking

 

[spliffas]

Yeah it drops but what I had atm was only lemon so i squezed it into my water with nutes, checked the ph and after watering soil’s ph went down a little. It was a bit scary though it is impossible to check water as juice goes down after shaking. No need to worry about ph now as i will ph down in 3 days don’t you think that those girls need extra cal - mag? As nutes i gave doesn’t state nothing about cal?

 

[KingJoe83]

Under led lights calcium is required a bit more then natural sun

 

[spliffas]

I am under hps, i can try to get cal - mag supplement or anything else works from household as calcium?

I am thinking about this one:

Should I give this to every plant or only on those which shows some kind of defi signs (rose and russian?)

Or maybe wait for a ph downer and do few feeds with 6.3 ph nuted water and check what happens first?

 

[KingJoe83]

Sure give her s try to watch some cal mag supplements can have high nitro so check the npk values . I use general hydroponics cal mag myself

 

[spliffas]

I’ll try 2 feeds with phd water, they should be in week 6 when I finish, if they will look worse i will try something as this will be near finish? As to get calmag i need 3 days in advance because of the shipping. Probably will wait for ph downer now, give it a try, if getting worse then will try to solve with calmag somehow. Let’s hope my ladies won’t die

 

[spliffas]

plus I increased nutage need to wait and see. And humidity is ~40, always was high now trying to make it higher as 40 I think is a bit too low in wk 5?

 

[spliffas]

Sorry for triple post just checked and yeah ph is too high, can’t wait for that downer now ^^
