    Turns out it was a magnesium deficiency.

    Well, that one is not uncommon. Good catch and here's to a nice harvest.

    You can either remove the affected leaves Or squash the affected areas between your fingers. They're little bugs living inside the leaves.

    Leaf Miners are not The Borg...not mites, or even whiteflies.

    If they are in veg, then pyrithrins would be effective, IIRC.

    Pyrethins and neem and silica all help to keep pests away. But they wont stop them. Bugs dont stop unless they dislike something that much. Or are dead.

    That's why I suggested to squeeze or remove the affected areas. They're living inside the leaves. A surface spray will only deter more from doing the same. It won't really help with what's already inside. As they're sheltered from the spray.

    The basic rule is that hunger will be yellow from the bottom up.

    That looks like some sort of over-feeding.

    Not certain...and just waiting out might be best. I might flush it with plain
    water and leave it alone until it was dry/light to pick up, keeping an eye on it
    all the while.

    Too much Mg can do that, or N. It might lead to dead patches on the leave.
    Time will tell.

    Good luck in any case, and hope for a real plant doctor to come along. :0)

    Heyall,

    I am a first time grower with 4 plants. Everything was great until a few days ago. My 2.5 week old plant went from perky to wilted in 3 days. The only thing that has changed in that time is that I put in 2 additional 18" florescent lights vertically in the grow cabinet. Could that harm my plants somehow?

    The first image is my 2.5 week old plant a few days ago and the next picture is the plant now.

    The additional photos are of my other plants in their current state. The 2 bigger plants are just over a month old but still rather small I think.

    The bigger 2 were potted in FFOF the younger 2 in a mix of FFOF and Happy Frog. All ofyhem are in smart pots on an 18/6 lightcycle. I have not fed them any nutes but I do Ph the water to about 6.5 and the runoff tests at about 7. These plants have all been watwred within the last 48 hours. Any help is greatly appreciated.

    I think that you might have some nibblers there.

    Neem oil, pyrithrins, etc. Good luck.

    (do confirm...just look at the underside with a decent loupe)

    I have to disagree. You CAN leave let them feed on ocean forest for a good month, even all the way to finish... but your results/yield will suffer. Of course thats the balance of too much vs too little, that every grower must choose for themselves. Some prefer the philosophy of "feed as much as possible without overfeeding& causing problems, to get as much as possible from the plant", others prefer the opposite - to be cautious & feed as LIGHTLY as possible without causing obvious nute deficiencies, to be extra sure that they dont cause their plants problems that cost valuable grow time (especially important with autos). Others try to stay in the middle. I prefer to err on the side of underfeeding, underwatering, etc, because its a easier & quicker to fix "too little" than "too much". Still... especially with aero/hydro grows, if you grow a strain out a few times & get a good feel for how much she can take (use a single plant as a guinea pig), you can get significantly higher yields by pushing a high feeding strain to the limit... IF you crank up the CO2 & PAR wattage commensurately. Aaand I will stop babbling & stfu now lol Sorry... made the mistake of smoking & typing at the same time! ✌
