Weird problem not all plants but not pests.

I am an ebb and flow grower, growing white widow from CKS, I switched to 12/12 on 4/25 so they have been flowering going on 6 weeks, I use technaflora receipe for success nutrients, I have a 70 gallon res in a closed room with co2. 1 1000watt hps in a air cooler hood about 30 inches away. Ph stays at 5.6 and Ppm has been at 1075

Also I added about 10 tablespoons of Epsom salts a few days ago thinking it was a mg problem that hasn't seemed to help at all maybe I didn't add enough??

I think I covered it all. Thanks in advance for your help.

This is my first time with the 70 gallon reservoir and I mixed 40 gallons of nutes then added 30 more gallons of water to dilute it some. I used to mix 12 gallons nutes and add 8 gallons of water when running a 20 gallon reservoir and that's been working fine

I'm with Harley on the nutes. Dial em back a tad.

WW is a known mg hog so you should supplement right from the start. For that purpose I'd use 1/4 tsp per gallon. Now that you already have a mg deficiency...double that till they catch up. With Epsom salts you need to make sure it's actually dissolving and not just settling on the bottom. It really sucks the heat out while dissolving so it's best to heat the water...add epsom salts and then nutes

But you have more then one issue. I definitely saw some interveinal chlorosis which is textbook mg def. But that's not causing most of the leaf fading. So carry on and keep us posted.

So I changed the reservoir and it was filthy the water was only 5 days old but this whole table is new, the water depth on the table is just a little deeper than my last so the deeper water got all the dirt off the media that hadn't previously been getting wet and it was filthy, I cut nutes back to 750ppm and used magical.

I'm starting to get worried what would yall do? Do they need more time? It's been 5 days since I changed water cut nutes back to 750, added magical, and Epsom salts 2 days ago

Flunkie91,
The Magical is already a MG supplementation...so probably didn't need the epsom salts. How much did you add? Possibly the extra Mg will make no difference and the extra S also shouldn't hurt anything. I'd dilute the nutes even further. And the plant doesn't need extra CO2 right now so can you shut that off. K.I.S.S.

Sorry I didn't notice that...but it is your grow. You should at least tread the labels and know what your giving.

Just saw the last pic haven't read the thread . Looks fried. I'd flush asap, keep ppm at around 550 after flush when new growth appears.. lock out from too much nutrient. Plants not feeding from roots, starting to eat itself. Flush would b my guess

Yes I know that was what the magical was for but after 3 days of it not helping that's when I added about 30 teaspoons Epsom salts to my 70 gallon res, I'm thinking flushing it is
