Brown specks on leaves

ChopperMcOGstarted grow question 2 years ago

I've noticed small brown specks appearing on the lower leaves. Does anyone know what might be causing this? I'm struggling to keep heat down and humidity up due to the weather. Could this be the issue or something else?

Your ppm should be at the 400ppm 0.8ec to 450ppm 0.9ec at this stage in their growth. 5.8 ph through veg, check often and 6.2 and 6.3 for flowering time...Most autos you stop increasing their food when you reach 600 to 650 ppm. only give more if they really need it and keep your water as cool as you can...

low ph and to much food. use the light feed chart and cut the amount in half. ph range is 5.5-6.5 so with you having it at 5.5 it can go out of range to easily

Do you splash it when watering and leave the drops on the leaf under light?

Your ph in water grows stays at 5.8. Over feeding is your problem...Guaranteed

To add to what Roberts has said, you need to raise your PH to a minimum of 6.2 in DWC for calcium to be absorbed... you may be giving it all the calcium in the world but if the PH isn't right, it won't help. Good luck!

Looks like calcium deficiency, and a spot where the leaf got wet and light was too strong.

Did I over-egg the nutes?The leaves turned like this after a feed and a Mosquito Bits treatment, guessing I over-egged it with the nutes? Plants getting close to me cropping them, might leave them to dry out from their last water then chop.

Cause for mottling leaves?I think this mottled leaf coloration may be due to slightly high pH or just stress from the repotting over the last couple of weeks.. Most leaves are fine but a few look like this. Any thoughts?
