Need Help Identifying Problem(s) Lots of photos

[Peregrin Took]

I have ideas about what could be causing these issues, but instead of suggesting what I think it may be, I was hoping some of you wonderful folks could take a look and let me know what this looks like to you.

I know I may be looking at multiple different symptoms/issues here, but any and all input as to what these look like would be greatly appreciated.

Did you recently spray with some thing?
Did you recently feed with something you had not been useing?

 

[Dankwolf]

Let me guess the plants further away from (i am guessing hps light) look better then the plants directly under it ?

 

[exploziv]

Is the soil mix PH level right? What are you watering with?

 

[Mystic Funk]

Those plants are all around nutrient deficient from top to bottom.
give them a complete nutrient and re-adjust your soil ph to 6.3 to 6.6






peace!

What are you feeding them? Without knowing anything else they look hungry to me. Some pictures look like P, and other pictures look like K deficiencies to me.

nice detailed pics. your plants are hungry. i would double what you're feeding em wait a week or two and see if they need more or less. how often are you watering? could be you're suffocating the roots too.

I ran into same issue and after over thinking it for a week and a half i finaly just went back to basics and started feeding a good npk fert. I hate when i make things more complicated then needed but i am happy my plants are back on track . powerd by love has the answer

Dankwolf - plants were recently sprayed with a weak neem oil, epsom salt, and fertilizer solution. All at 1/2 strength. I am typically not a big fan of foliar spraying, but I wanted to eliminate magnesium as an issue, plus some neem as preventive measure.
I had been considering the possibility of light burn too, but many of these symptoms developed while the closest plant was more than 14" away from the 600w cool tube.


Exploziv - The pH has been high, up near 8 a few weeks ago, but is coming down back to in range ~mid to low 7s currently

Mystic Funk & Who dat is - I agree, some classic examples of P and K deficiency. Perhaps due to lockout, or maybe these gals are just hungry?
I have been feeding 12-4-8 chemical at nearly full strength.


PoweredByLove - considering I am giving almost full strength nutrients already, I feel like I should rule out pH lockout before going too crazy with increasing the feeding, agree? Watering has been every 6-8 days, depending on when the pots feel super light. I think over watering can be confidenty ruled out.

Maybe a higher P food is in order? (Currently 12-4-8)

Thanks for the input so far everyone, please let me know if there is anything further I can help to clarify.

Yes, it seems like you are feeding them a pretty exclusively veg blend. I would supplement just a little extra P and see if that doesn't do it for them.

I wouldn't know what to suggest however since I only grow organics, sorry. Some of these other chem guys in here will have some good suggestions I'm sure

 

[exploziv]

I'd do a half strenght nutrient watering PH'd to 6.5, then let the roots breathe for a bit while deciding what to do next based on how the plants react.

Lock out

Lock out

Another idea:

The fertilizer I have been using in my foliar spray, and in my regular feedings, contains iron and zinc. What if, the high pH caused a lockout of these elements, and now I am actually seeing a toxicity of Fe and Zn ....which can then prevent phosphorus from being properly absorbed?

Eh?

 

[Dankwolf]

I would say two differint typs of lock out and a bit of of light burn if plants are worse the closer they are to light .

 

[Dankwolf]

1# Hows the run off look ? Salt build up and lock out.
2# with that much n you might be locking out k ?
3# ph lock out

 

[Superscript1]

It's not phosphorus lock ...you need to flush your soil with reverse osmosis water if u can ..do u know the ppm of your water ? You can flush well and catch the runoff and test the electric conductivity / ppm to see what might be going on ...it's definitely micro nutrient ,n yes ph your soil and water...good luck

Check for Root Aphids using the potato test. Good luck. -granger

 

[Peregrin Took]

I agree Granger, these symptoms do look like they could be root aphids.

After six hours with the sliced potato I found nothing that looks like aphids, to me atleast. I did however find plenty of these little dudes crawling on the potato. Much more slender than an aphid, with long antennas on the larger ones.

To the eye, with a shitty magnifying glass, they look to me like either little silverfish, or springtails (maybe being a little optimistic with that one).

I did my pest to try to get some pictures of them. I'll put them up in chronological order, zooming in. The paper they are on is from a small 4x6 pocket notepad.
