    Well when you can get some. It's not an emergency. That's why u want to mix perlite, vermiculite or peat in to help with drainage and keep it from compacting.

    Do that next time. Vermiculite is cheaper than perlite. Use a bit less than 1 part to 2 parts soil.

    U have malformed spotted leaves. Go to talking nutes with BB thread and show him the pictures.

    I wouldn't change the pot tehy are in, they've done fine until now, roots can grow through concrete given enough time so compaceted soil at this stage is just due to it settling over time and with each watering.

    It could be fungal, there are a few klinds of fungal diseases that cause rusty spots, but not usually so dark, the curliong of many of the leaves looks like overwatering and if so then they have been over-nuted too.

    If it's fungal there's nothing you can do so i'd give them pure water on their next feed (in case it's over-0watering/nuting) but wait unti the pots are very light, around 50% dried out.

    To prevent fungal infections like this, you can put sulphur powder on the plants when they are 4 weeks old or more. You can also get preventative fungicides.

    One cause of rusty spots is water spillage on leaves during watering, so best to soak up with tissue or cloth if this happens.

    Thanks bro, those are some good photos for learning. I bet everyone that grows has seen those kind of leaves in our own gardens at one time or another. Don't pack your soil and water your soil slowly! Over compaction, lack of aeration, and the over-watering of your soil, can all lead to anaerobic activity. Over-watering can look like nitrogen is unavailable to the plant and will appear as the plants or needing some. Also,over watering an heavy organic soil can cause too much Nitrogen to be released into the pot and cause toxic Bear Claw. Watering is the Key.

    I do sometimes think reading leaf symptoms for nutrient deficiencies is a load of old baloney if you are in coco or hydro it is usually PH, lights, heat or something else rather than a specific deficiency of any one thing. Lets face it if you are mixing your nutes correctly it shouldn't be an issue and certainly not for a specific nutrient apart from maybe nitrogen overload. In soil it will of course be relevant.

    Reading plant leaves for pests and predators is different matter and could make or break your crop.

    Yes, any good food won't need correcting, one hopes. About the only exception is K or Mg hungry plants during flowering, where running a high enough CF to satisfy demand, can be a bit toxic. Even then, it's only in recirculating systems where it gets depleted enough to start screaming at people. In 'run to waste' most problems point towards a lack of runoff. Leading to lockout.

    My older girls that won't veg properly, have led me to growing with flower food and Nitric acid, to keep them happy. My water is hard enough to need a good dose of Nacid. Much of which is available N (somewhere between 30 and 50%, I forget)
