What could this be?

What’s wrong w/ her?!

I think I gave her veg nutes to far into flower
Thinking I have a nitrogen toxicity..?

but the leaves aren’t very dark green so I’m not sure.

I’m taking all advice, criticisms, etc.

Tell us more about your grow ...

lights
cycle
temps
Nutes
medium
ph

looks like a ph issue more than a veg nute goof. Besides a simple watering between feeds will clear things a bit before resuming a bloom feed. Plus if this is an led grow , calmag becomes a necessary evil at times.

Thanks for your time man
Lights: mars hydro ts1000

Today marks Week 5 of flower

My furnace in my home went out recently and my temps have been fluctuating a lot.. sometimes down to 60* at night. Furnace is back working now, she’ll stay at 70-75

I’m using the plagron series at half strength.
Started 3 waterings a ago and I gave her quarter strength veg/ quarter strength bloom, also half strength additives, for 3 straight waterings.
on her most recent watering.. after the yellowing, I gave her straight water and am planning to continue the nutes at half strength bloom nutes and half strength additives.

growing in FFOF soil in a 7 gallon fabric pot.. I believe the nutes are run dry though which is why I started using the plagron.

I keep my ph between 6-6.5

Maybe Ca deficiency? I'm still pretty new at judging deficiencies, so definitely get a second opinion, lol. My first round of FFOF started needing Mg later in flower. I would give them a little cal-mag and watch them, but again, wait for the pros.

I would stabilize that ph up from 6.5 - 6.7 ... FFOF is ph at 6.3 so , if you run under that ( like 6.0 as you stated ) will lock out things.
The small spots concern me , check very carefully for bugs ... scope the leaves or eggs or bug damage .

Believe it or not your nitro seems to be close ( minor claw ) but fade is from something out of uptake. Cooler temps DO CAUSE UPTAKE ISSUES ( SLOW ). I would get some of that “ purpling “ if night time is too cool. So I added a seedling heat pad under pots and tray or add some environmental heat ( heater ). It gets into that VPD issue of temp and RH to find the right range to keep things moving along.

Ya, those spots raised my attention too, but didn't want to bring up I the dreaded "B" word, lol. It was wishful thinking saying Ca, but I'm curious, and want to hear what the experts have to say in case I ever see this.

I'm always learning. I'm solely hydro and I think about trying soil but it's far more complex because you have to rely on a healthy microherd. I figure during the winter I might be able to do it but in my high heat environment I wouldn't get away with my deviation from VPD parameters. Budz gave him some good advice.

@Budzbuddha
Checked for bugs.. didn’t see any but I will keep a look out

Im also seeing that calcium is locked out at 6.0-6.2 which is a big red flag because I know I’vehad the ph below 6.2 at times.. (I use the drops so it’s not an exact measurement.)

the temps have been corrected and from here on so will the ph.

should I buy some cal mag? My local hydro store carries a brand(can’t recall the name) that has no nitrogen in it.. but that stuff is expensive and I was considering dolomite lime.
Id like to hear what y’all think about the calmag vs dolomite lime

i just use this or calimagic ...... but there are many other good ones like botanicare. They all do what you need.

Hey @curious2garden, could GanjaGreg's problem be Ca deficiency? Here's the leaf that I was questioning.

That damage looks eerily similar to spider mite damage. Colour is a bit off though so I may be wrong, however, the pic is taken under an LED and not natural light, so that could be deceiving. To be safe, look underneath of the leaves with a magnifying glass or loupe to see if you find any tiny black dots running about. Also look over the entire plant for any webs.

I would check for pests...

Your plants appear to be short on Mg and P....whether via pH, nutrient lock out or it's just hungry. Good luck.

So I’ve been checking for pests...still no sign.
I haven’t got a chance to get my hands on some cal mag but I will definitely get some ASAP.

. I fed w bloom nutes and an additive called green sensation by plagron..
Bloom nutes are 2-1-3
Green sensation 0-8-9
She looks better.. I’ve lost quite a bit of fan leaves though I hope she recovers

also I’m starting to notice discoloration on some sugar leaves..!?
Really stressing me out...again.. what do y’all think this is?
