-- hey bud, looks like a few things off here,... >> what's with the droopy leaves? Can you tell us if this is from possible over- or under-watering? That alone will cause pH and nutrient uptake issues,... root damage, poor uptake, causing defc.'s even if the nutes are present,...
>> symptoms look mixed, and pretty muddied up,... as mentioned above, the droops make it harder still to pin down what's what here,... lowers look N defc., but mid and upper with color loss could be a few things, too generic to be sure of specifics,...
>> looked at the soil,.. is this the hard or soft water version? With your water at 7.5, it sounds hard; Ah! I see the info, it's about 250ppm, which is decidedly hard water.... this may also have bearing on the actual in-pot pH and ion load in there,... this soil seems decent for some basic nutes, but far from well covered, especially secondary and micronutrients,.. NPK is just the start, and without any other inputs of the latter, the plant is probably needing some more of them by now,.. worse, with little extra NPK around, the plant is low on reserves so by bloom, when demands really spike, she has little in the tank to spare,... plants will take up and store nutrients that they don't use right away, usually in the fan leaves,.. but that only covers a limited number of nutrient elements,.. several are poorly mobile to immobile within the plant, meaning once locked into tissues, can't be removed and translocated to new growth where it's needed most,... Buffering capacity of the soil
>> pH'ing, with organics,... usually, it's not recommended that you adjust the inputs, true,... unless they are wildly off,.. but more importantly, it's what the in-pot pH is that matters most,.. once in there several other influencing factors are in play,.. to say just because you're growing "organic" that the soil can't drift off-pH is patently false,... always monitor in-pot pH,.. best tool for this is a good quality pH probe, like the Accurate 8; those skinny cheapo units are not to be trusted, I've tried and tested a few brands,.. all sucked vs the A8,... at 7.5, if that was true, you'd have worse symptoms, as many micronutes lock out fast above 6.8,... still, it's likely too alkaline in there,...
>> soooo,... do you have a TDS or EC meter? have you calibrated your pH meter recently? A crude test of both runoff pH and TDS/EC could offer some clues about what to do next, collect in a clean receptacle!... But firstly, getting the droopy leaves cause figure out first is top priority, then determining the in-pot pH best we can,... meantime, adjusting the water to 6.3-ish is a start,... nutes solutions are usually acidic already, but check anyway,...

Thankyou so much for your in depth reply mate
I do have a TDS meter that is calibrated and I will check the run off on one of my plants and post the information here. I will look into getting the A8 soon to get better reading. Is the soil any good or are there better ones that us UK growers have available, my first two grows was in Biobiz ligth mix and was both pretty successfull I just wish I had kept a journal of what I done on those grows.
Hello,
I replied to this thread because I'm growing some auto massassin and I've found that it's quite hard to find information relating to this strain.
I'm not that experienced so make of this what you will, but I hope that someone finds this useful.
The first thing that I noticed with the plant was that it kept going floppy. It fell over as a seedling, which set the theme, but then it continued to wilt (fans almost hanging vertically, but no stem bend) through it's stretch. Over watering, temperature, nutrients and even it just being the plant 'having a sleep' were all internet researched based considerations.
It was pH.
To set the scene, small tent, 1 litre pots, john innes number 2, a bit of tomorite once a week, LED light from a popular online retailer that might sound a bit like 'spamazon'.
I succumbed to obtaining a pH meter. My pH was 7.1, so probably a bit alkali.
I'm not a massive fan of banging chemicals in consumables, so I used lemon juice, initially about 40 ml in a 500 ml bottle. Then a glug of that in a litre watering can. Job done...
... for a bit. Then things started going yellow, from the bottom up. Eventually I got that down to a lack of nitrogen.
The lemon juice was stopped. I put coffee grounds on top of the soil and continued as normal. I've had to replace the grounds a couple is times due to mould (be a bit careful about this), but things have been going OK.
I hope that helps someone, somewhere, get a bit more trashed.
