Nutrient toxicity/ deficiency? Lockout? Please help!

Livegreen31 · Dec 2, 2019

Hey everyone... hoping someone can give me some of their opinions on some bronze/copper spotting on my plant. This is my first time growing indoors and I am trying to identify my problem before it gets worse.

I have a sativa (unknown strain but 13 finger leaves) in a 5 gallon pot in ocean forest and happy frog soil - in its 5th week of veg.

PH runoff was 6.8 after I last watered. Did not use nutes in last watering - I used nutes two watering ago and noticed a small amount clawing after using the fox farm nutes. I figured it was snowing some signs of nitrogen toxicity. The clawing encouraged me to filtrate a gallon of water and water @ PH of 6.6 Two days ago.

today... I have noticed some weird spots. I have uploaded pics - any opinions/ help would be appreciated.

Personally, I’m thinking I need to either A) flush it until I get a PH of 6.5 B) add some calmag

I just hope it’s not a rust fungus. I did look under microscope and do not see any signs of bugs.

did you add lime to the potting mix?

Fox Farm soil mixes and Nutrients don't have much calcium associated with them. It looks like and Calcium issue but it's hard to tell under the Blue/Purple lights. I've seen these on lower leafs with our LED's. If you are seeing some clawing from N you may want to look at Cali Magic since it has no extra N. Fox farm cal-mag mix is lite on N but can over N your plants yet again.

Thanks for your reply, I ordered cal mag this morning. I took the 10 “infected leaves” off yesterday and watered this AM with 6.5 PH 80 ppm. I only saw 1 infected leaf today... maybe I missed it yesterday... maybe not. If the problem gets any worse, I will add calmag too it.
