If you are having rust spots between the veins and deformed leaves that is a classic sign of a Calcium/Magnesium deficiency or you have a PH problems. Or you are having a combination of both, but without a picture its hard to tell so you should def put up a couple photos of the plant from top to bottom and some leaf close ups so someone can pinpoint the issue at hand.

Does not look nute burn. To me actually looks like u have bigger issues than nute burn. Test your ph of your soil.

How does soil ph change? Is it added nutes etc.? My soil is balanced at 7 i think. I have happy frog. And i use organic garden lime which brings it to a neutral 6.5

The soil medium doesnt matter what the ph is because everytime u r feeding u r changing the ph. Your water changes the ph and when u add nutrients ur changing the waters ph. As nutrients break down and salts remain in the medium it changes.

Yes lime will buffer your soil to keep it in a stable range but that doesnt mean that the plant is uptaking the nutrients in the proper range at all.

for example if your medium when its dry and needs watering is at say. 7.0, then u go and feed nutrients after mixing them come out at a 5.6 than you just altered the medium to a 6.3 roughly. Than if you over fed the remaining salts can change the medium even more because they become concentrated in your medium further changing the ph... so then you run into other issues like the ones your plants are showing.

If its just one plant out of 10-20 than i wouldnt worry about it. You could just flush that pot out w ph balanced water for a couple of feedings and see what happens.

If u are feeding w all organic nutrients than u also dont need to PH as long as you have bene's and microbes innoculating the medium properly to break down the nutrients in the containers.

If you are using synthetic nutrients than u need to be checking the ph going into the containers every time u mix ur nutrients to make sure ur in the proper range. It could be that everything is fine and that one particular container is experiencing a salt build up and locking out nutrients causing what appears to be a ph issue because of excess salts in the rhizosphere which would mimic a ph imbalance even if everything else appears to be okay.

So feed w plain ph balanced water wherever u need to be and flush the plants out. I would than collect some of the run off and check the EC/PPM of that run off and make sure its in the acceptable range. And maybe that is the problem with that plant something minor. Just assuming by what ur telling us that everything else seems good and not having that issue. Some plants react different even when all things r constant it is what it is.

sounds like my problem entirely. I need to buy a ph tester for soil.and another grower said i wasn't suppose to feed nutes every watering. So now i do ph RO water and next watering day i go ph nutes.
