    really looks like it was caused by something you have sprayed directly on em,
    strange it's only affecting the second set down though

    weren't they nice and green a few days before you sprayed em?

    Cheap washing up liquid 1st time and then soap nuts this time mate

    Just given them a foliar at 3ml/L Calmag, see if that improves um...

    Side thought, should i be PHing whatever im spraying or does it not really matter?

    My ph pen was 0.1 below where it should be too so ive been feeding at 5.7 PH so could be down to being locked out from Magnesium! Calibrated the pen now so fingers crossed along with the foliar theyll be golden in few days

    might have been spray no1 with the washing up liquid mate,
    did they react after the 1st spray?

    theirs something called 'Phytotoxicity' after the water evaporates on the leaves the residues from foliar feeding can be left behind on the sprayed area
    it can cause yellow/rusting

    foliar is direct feeding so best around 6.5ph but other ph will work, unsure about 5.7 tbh
    haven't ever tried it

    --added

    your not using ph up/down with your foliar spraying mate???

    Thats what im thinkin mate, residue left behind... would make sense as they looked better after the last spray

    No mate, not adjusting the foliar. Wasnt sure i should be but ive never done it so...

    The 5.7/5.8 is the ph of my feed

    being honest mate i wouldn't worry about it,
    ur plants are really healthy and ur doing a bang up job,

    think the washing up liquid on spray 1 did the damage but it's just a few leaves,
    the top growth isn't affected so was a good lesson to learn

    mon the pineapple my friend!

    Yer looks like damage from the spray, and everything else is fine, keep going mate. If there are any changes, come back. But I'm pretty certain thats an effect of the spray. Gotta be careful with dilution, if it's too strong, itll burn your plants.
