Should I be worried

[Waira]

plenty good Sgt., thanks!.... I think it sort of looks like a K issue, but usually the margin 'teeth" tips get fried first,.. this tip/edge wasting looks more like a nute burn issue, though that;s odd given the light feeding,.... I still think this is from the bad dry-out as explained,.. do you have a wetting agent? Sometimes when the soil gets really dry, it won't rehydrate evenly, and when you water it again, it partly repels it away from these dry patches,.. does the pot feel light? the wetting agent helps water penetrate the potential dry patches and even out the moisture,... the dead tissues, are they going crispy, and is it progressing still? After-effects from the dry out can linger,.. also, a pH reading of the soil would be wise to get,... what soil is this? do you have a pH probe? Accurate 8 is a good one,.. otherwise, it's the dubious run-off test method, which I dislike for several reasons,... tell you what, depending on what you say, it might be good enough to just collect some run-off from a clean saucer or something, after watering with only water,.. it's not accurate for actual pH, but it can give a hint at if things are too acidic or basic in there,.... no flushy unless it's really bad!

The soil is biobizz all mix it has been mixed around 60 / 40 with perlite and pumice stone
never used the pumice stone before picked a couple of bags from IKEA could this be the problem
I did some research online and its a volcanic rock like vermiculite and I have read other growers using it with out problems

Unfortunately I don't have a probe I will test the run off on the next feed as far as I know the pots where dry they have some weight difference from freshly watered to a 3-4 days later when i water again but i always make sure the top 4 inches are bone dry before I water and if the pots feel heavy I hold off for another day or two

It could be nute burn I am using fox farms and its notorious for burning plants if your not careful I am growing 4 different strains but there all getting the same water/feed could this be the problem

I am on my way home from work now will check on the ladys soon as i have had a shower Thanks for your time and help appreciate it just hope I can get it under control will be a shame to lose any of my baby's

...water sooner mate, don't let it cycle that deeply,...it's stresses and even kills roots, especially ones trying to expand upwards,...yes, the hefting test- - score that wetting agent Sgt., it's also great for any foliar applications too, even critical for treating deficiencies and killing pests! But they way it cuts through dry-compacted soil is magic,... I like Coco-Wet, organic, inexpensive, very good product....

OK thanks for the help not sure what's going on with this sour diesel can she recover or should I cut her and concentrate on the other lady's

...need a whole plant pic mate, to assess,... it's Mg defc. there, usually an easy fix,... you using Ca-Mg on her?
