    Default Sick preflowers

    Evening all, just got back from a week in Spain and my girls have started to flower.

    But I’ve noticed one of them doesn’t look too great, all the other leaves are looking ok but the pre flowers don’t.

    These are autoflowers
    Week 5 from sprouting
    Only been fed water
    250mh up until week 3 then 600hps
    11 litre pots - B&Q multi purpose verve/perlite

    Shit pictures but you can see what I mean

    Id suspect a trace deficiency given the yellowing or its conceivable its a pH issue.

    Whats the pH of your water? I feel this is unlikely but worth considering

    You could give her some molasses and/or rockdust to cover any trace mineral issues

    Off the top of my head the pH of my water is around 6.0 give or take 0.2, from my first coco grow. Where would I get molasses and in what dose? Cheers Gaz, strange how it’s only on this plant out of the 5

    Yeah very odd mate, could be a sign of things to come on the others???

    0.2 is a big approximation mate, as 6.0 is 100x more acidic than 6.2....

    Im my opinion the soil should buffer that difference anyway so its unlikely important

    Mollasses from ebay and use about a teaspoon per litre mate, if you can afford it get some rockdust as well from fleebay and top dress 5 tablespoons per pot

    Where 6.0 is 10x more acidic than 7.0, 6.0 is therefore 2x more acidic than 6.2. Critical in coco...not so much in soil is how I'd look at it.

    That said, I think Trex is closer with it being a watering issue - the coincidence with being away for a week is strong.

    It's not.

    6.0 to 7.0 is 10 times.

    6.0 to 8.0 is 100x (10x10 - log scale)

    I wouldn't bother with the dust n molasses Lewis, just give a light feed as Herb n Trex said

    Im still standing by a low grade potassium deficiency but the feed will sort that I imagine

    Oh my rationale...

    Potassium availability drops of quickly in below neutral pH. Even at 6.2 it could be a factor causing limited uptake of potassium.... Just my crazy mind lol..

    Just listen to the others

    Just for interest purposes

    Wouldn't hurt to get your pH of your inputs to 6.8 each time save worrying mate at least

    Adding rock dust as it's a weatherable material increases the pH 'buffering' capability of the soil btw

    It can take yrs for rock dust to be available tho gaz .

    Worms will put ph in its place fast enough . Those are the true soil warriors .

    Cheers for the input lads, I did get my brother to come and water them but they looked a little dry so he may have forgot the second feed. I’ve given them a good watering with some feed at 2ml pl so il see how they respond to that.
    Definitely changing soil after this grow though nothing but problems since the start.

    Little update, it has been a few days since feeding and one of the girls seems to be getting worse so I’ve pulled her. Gutted but it has freed up some room for me, just hoping the tallest girl starts to flower soon because all the rest have.

    Considering pulling them all, waiting until i finally get my invisible sun and starting again. So annoying

    Sorry to here this mate you can still try my recommendations mate
    Those plants dont need food, there is a deficiency at play here and I recommend getting your pH to 6.8 and top dress rock dust with a feed of molasses

    Im. Still sticking with potassium caused by a low soil pH at around 6 given they have had that water from the start and while not a true pH issue as such, its causing a poor uptake of potassium

    Ph to. 6.8 and make up molasses and use that to water in a top dress of rock dust and give her a week to ahow signs of improvement.

    I think this plant is past saving Gaz mate, nearly at week 6 and she looks shitty. Il try what you said for the others though where would I get molasses from?

    Ebay for both molasses and dust but please get your pH to 6.8 first so the plants can easily uptake potassium
