Stick is Stumped Once Again!

[Another One Bites the Dust1]

Stick is Stumped once again, which those of you that know me doesn't take much
So, here I am needing some assistance.

I have green tips drying up and dying on plants of every stage, and in different locals. Clones, mother plants that are in cabs in my house. And plants in veg and flowering in an out building. Different strains and phenos of photos.

All environmental conditions are spot on. Temps, RH, ventilation.....
Running Pro Mix and nutes.
Checked my soil last night with an Acu 8 soil probe, as well as run off. PH= 6.5.

Green tip leaves are drying up and dying. Been battling the dreaded spider mites for a couple of months, but think I have them in check finally. I have sprayed some of the plants several times and some new clones just once. Thought maybe the residue may have been the issue. Sprayed off some new clones with Phed water several times to no avail. Here are some pics.











Thanks!

Hi Stickman :hug:

You know i've never used promix before but i found loads of contradiction when i looked into the ideal PH range.
Without having used it, i can't really reccomend and range, but just for info some are treating as pure hydro and going in really low (like 5.1-5.5) and I see others are using a range 5.8-6.2 (which seems more sensible to me as ph usually swings up)

It's all hearsay from me here unfortunately, but perhaps it's a PH issue.

Sorry i cant help more!

Ok, here are some whole plant pics from two different girls/strains in different stages of flower.

Not sure if you can see much with these whole plant pics. The HPSs were ready to go off. Also noticed Plant 1 and two showing whole leaves curling up, and looking like they may possible be dying. :dunno:

Looks like I have some Def issues going on as well. Cal/Mag? Again my PH is fine.

Man, growing Outdoors in TLO/supersoil sure is SO much easier!

Plant #1, same plant as first set of pics.














Plant #2, This girl has more whole leaves curling up and getting dry.









As always, Thanks for your help! :tiphat:

Thanks for chiming in Blue, Pop, and briman.

Haven't noticed any gnats, and yea I was thinking possible Salt buildup, but this is happening to some Mothers I have in my TLO, and they have been doing great.

The dry tips are also happening in some very high CBD clones in a different medium all together.

The clones, and Mothers are in a completely different building, and this just started happening to all the plants, in just the last 5 days or so.

Thanks again!

Stick my brother, its hard to tell from these pictures but the crispy leaves look blackish and crispy instead of brown and dead. That to me suggests phosphorous and your leaves look a touch blueish green as well. Copper generally shows with yellow and white tips. Is this what the leaves look like up close?

Thanks for taking a look brother Dub!
Some of the leaves look similar, but I have been hitting them pretty hard with phosphorous.

I was so sure that my PH was out of whack, by what is going on. But it the soil, and run off were fine, using good instruments.
