    Default Brown spots on leaves??

    Small grow - this is the only plant.
    She's about 12 weeks old.
    Growing in soil, 22ltr pot.
    HPS 150w
    Have been using Plant Magic Organic Grow every 2-3 days

    About 10 days ago I re-potted from previous smaller container and while moving the plant back into the cabinet it fell over and got lots of watery soil on the leaves.

    About 2-3 days ago I noticed brown spots on some of the lower leaves, and on the top the leaves are showing wilted brown areas at the edges of the leaf. The leaves also seem to have become paler than normal.

    I was about to flip to Flower this week but obviously don't want to do anything now.

    Help!!

    Whatre your temps mate? Theyre canoeing abit, could be heat stress?

    And not a clue if im right but the spots id say a calmag issue? Have you been feeding either foliar or in with feed?

    Temps seem fine, under 25C even by end of 12 hours on.

    I've not given CalMag yet as I didn't use it on my last grow and she was fine. I'll dose her up tonight. Cheers

    I gave her 2ml CalMag last night with 1 litre of water. Should I give her another 2ml tonight?

    If you have spots already best way is a foliar at 3ml/L using warm water. Try spray just before/after lights out so the plants dont get fried. If you cant do that just raise the light right up and check back after a couple hours 👍

    I tend to feed mine 0.5ml/L once weekly and that seema to keep issues at bay

    Yeah mate, just give them a nice drenching
    👍

    Keeps those temps fairly warm and if you have your fans for circulation just gently moving the plants theyll dry out fairly quick mate
