HELP!!! Rust!

[JaYbIrD91420]

Ah ok, and is it on all 11 plants?

Yea all of them have at least a small spot of it on them.

If they’re all being fed the same then maybe something isn’t right with the level of nutes/ph or something similar. I can’t categorically say it isn’t a rust fungus, just that iron staples wouldn’t cause a rust fungus. There are 1000’s of pathogens that can cause a rust fungus.

None of the damaged/spotted leaves will ever go back to being “normal” when we find a solution to the issue, the damage is permanent. But new growth is what you want to be watching and also watching to see if the currently affected leaves stop getting worse.

You could flush all your pots with fresh, ph’d water to “clean out any salt build ups and clear any other nutes from your soil, then water with low levels of nutes to sort of “reset” your soil

Ok thanks! I'm going to flush them all today. I don't see any new spots in the past few hours so maybe that's what it is. I will continue to look.

These are my girls today. Any help or advice would be appreciated greatly. I'm trying to test the PH of soil now.

They look very small for 5 weeks - these are my autos at 5 weeks (3 plants in a 2x2ft tent):

Something has stunted them really early on. Did you plant in their final pots or transplant them from something else?

Like I said before, none of the damaged leaves will get better. The ‘dead’ patches on them will just crumble away. How much water are you using with each watering? I do think some of the pictures show signs that they’re over watered

I put 2 different soil samples in 2 different then tested them. One read 5.02 the other 5.20. What do I need to do from bere?

That’s way low. I’d flush them, so pour plain water, ph’d between 6.5 and 7.0, through the soil, pour more than the volume of your pots through (e.g. if you’re in an 11 litre pot, pour through 12 litres).let it stand for about 5 mins to let the water soak up nutes/salts, then flush again with another 12+ litres of 6.5-7.0 ph water to flush out the previous water (now holding most of the salts and nutes) you poured in. Check the ph of the run off after the second flush, if it is still really low, flush again. Ideally you also want to check the run off with an TDS meter to see if the ppm of the run off is the same as the water you flushed with. Eg my tap water is about 200ppm, as you flush, the salts etc dissolving in the flush water will increase its ppm. Once your run off ppm is the same or close to your flush waters starting ppm then you know you’ve washed out all the salts and nutes from the soil. You can then mix up a feed and water your plants knowing exactly what level of nutrients and salts are going back in to the soil

Thank you so much! What can I use to raise the ph once I've flushed or before hand until I can flush them ASAP?

I transplanted them last week and I've never over watered them. I changed light last week to hps and changed right back last night bc of heat issues. I dont think my vivosun 6' filter and 440cfm fan is pull enough air out.

How much water are you giving them and how often?
