New to hydroponics, assistance needed

[Lynch_Ironside]

Update
So the other day when I did a res change on the white widows I was in a fog...probably due to the wake and bake. some how I added nutrients at half strength and had a ppm of 310 this morning. So after doing the math and removing 5 gallons I added back a solution of 1270 ish bringing my total ppm to 680, target was 650 but I'll get it dialed in next time around. Lux 46-50k vpd 1.06 ph 5.4-5.5

Do you guys run cal mag throughout the entire grow?

At this stage would 5 grams of Epsom salt be sufficient for a 10 gallon res?

On the original glue res, my 2 surviving seedlings are not doing well. I think it's a calcium deficiency would you guys confirm this for me?

Ph 5.8 ppm 420 vpd. 97 lux 13k res temp 65
I think the ppm is rising due to the amount of water evaporation. I've tried to mitigate this by reducing the amount of holes on top of the res. I would like to get this deficiency under control. As always your help is greatly appreciated!

Looks like root stress of some sort.. they have roots in the water yet?

Yes they sure do. I'll grab a pic hang tight

I hate to keep asking but this is tap water?

Lol it's all good man, I see you trying to teach the world how to grow, there's only so much a man can remember
Its ro water.

So yes cal mag through the grow until last week. Epsom salt if you see a mag deficiency instead of adding more cal mag. 0.5-1gram per gal should be plenty to fix that if it happens.

Thise root temps seem to cold for me. I would be around 72f personally

Thanks man. I'll order an aquarium heater

Update... I was toying with the idea of doing a heavy defoliation on one and just a light strip on the other but I chickened out lol
Just took most of the older leaves and some that were blocking flowers.

Update. Things seem to be going fairly well. Aquarium heaters should be here tomorrow. I've noticed on the white widows are starting to get spots and deadish patches. I've been keeping my ph a bit lower the last couple of weeks 5.3 to 5.8 Res temp is at 63f now with the weather getting colder its dropped a couple degrees

Plan to bring the res temp to around 72f and bring the ph to 6

Ppm dropping about 30 a day

Its ro water

 

[Lynch_Ironside]

So this seems to be spreading. The closer I look the more I see. Any ideas on what's causing this? @Aqua Man if we were in Gotham there would be a big spotlight with a maple leaf shinning at the sky right now!

Could this be due to temps in res, 63f

Its ro water

Looks like russet mite :(

Do you have microscope or loupe????

 

[Lynch_Ironside]

Do you have microscope or loupe????

I do... let me see what I see

 

[Lynch_Ironside]

I'm not seeing anything under the microscope... could it be anything else? It seems to be only hitting the growth in the middle of the plants

Look on the underside of leaves and see ifnu can clip a sample of a lower branch and inspect

 

[Lynch_Ironside]

I'm not seeing anything. Dont russet mites attack new growth?

 

[PK1]

hey lynch, did you adjust ph?
