This white widow autoflower is getting spots on the leaves, I also noticed a little brown or reddish colour on the roots. It is in a dwc system. I changed water and cleaned system today. I am using general hydroponics 3 part system and cal mag. I put 1/2 tsp micro,1tsp bloom, 1/2tsp grow and 1/2 cal mag per each gallon and that puts me about 400ppm as well ph the water to about 5.7 any suggestions on what I should be doing?? It is hard to see the reddish on the roots in picture

Try going up around 600ppm and a little more calmag

Also write down to ph and ppm in the morning and night so you can tell what you need to do

calmag deficiency if your PH is stable.... it would require some large swings in PH to acquire metallic fishscales on the leaves (the pictures kinda look like fishscaling on the leaves in a few).

How are you measuring the PH of ur soil?

What kind of soil is it? is this miraclegro? Whats up?

The first 4 pictures are of a plant that is in dwc and it seems to be having large ph swings.
As for the plant in the soil I am just giving it water with nutes that is ph ed when the soil is dry

be sure that you are not overwatering at all. you shouldnt be watering more than maybe a half gallon every 3-4 days right now.

Get rid of the miracle grow and go get nutrients made for weed that is going to be smoked.... Not veggies that will be eaten.

Do you mean get rid of the soil? The soil I used was miracal grow but the nutrients I use are general hydroponics 3 part system with cal mag. Are these good nuterents?

Hey guys, back with the white widow here again. The plant seems to be growing awesome. Did some LST on it as well. I am still getting the dots all over the plant, I change my water out every Sunday, the plant seems to like the ppm around 400 ish. I am putting 1/2tbl spoon of grow, 1/2tbl spoon micro, 1tbl spoon bloom and 1/2tbl spoon calmag. My water temp in the dwc is around 21 to 22.5 c. I do notice if I add let say 5.7 ph 24hr later I am almost at 6.5. Constantly adjusting ph down. Any suggestions?
