Twisted first hydro attempt

[Twisted]

Not sure really whats happening here don't know if someone has an explanation, 3 of the girls are growing flat to the coco/pebbles and about 5 or 6 have a thick lump of growth in the middle of the plant?

If I top up the res say with 100litres of water do I just mix full strength and add?

As Sticky says the purps stems kinda make you think cold and wet soggy roots. Usually the purps cold stressed out look can or does start locking out phosphorous which i can see signs of in some of the yellowing up leaves, lack of P can also cause plants to struggle flowering. But yes i think it maybe an idea to warm those roots up, i use an aquarium heater in my fert mix and set it around 23-25c which is slightly high but by time i get it to pots its cock on temp wise, my pots or grow medium is running around 20c, the heaters are cheap enough. But yes i would say this is your problem caused by cold wet soggy roots. A bit of h202 or fulvic acid will help with uptake through roots even both, using air stones will help with uptake as well and dropping ph to 6 or just below may help but 6ph is ideal. If they're in pots then let roots dry out a few days or so too. Maybe an idea feeding every few days after till they recover and grow out of sickness.

I mix 60 to 80 litres a time with A&b added firstly then all additives i use like silicon and fulvic and add last. If using silicon and ferts are cloudy and not clear then your ferts aren`t mixing topgether right and their not much cop for use on plants, quick fix usually is add fulvic acid last before ph`ing and this tends to bring them back clear and good or lastly do your ph`ing with ph down last and this will bring ferts back together and crystal clear.

I think you may be right scoops, I checked the res temp last night it was 13c I didn't think about that tbh.

Is there a chance am aquarium heater could melt the flexi tank?

i doubt it, thsoe heaters are used in plastic fish tanks all the time so would have thought it would be ok.

Quick few photos see what u all think, I think they are drooping a bit however it was lights off time so maybe that the problem.

They come with two sticky sucker typo things, i just stick mine on back of a plate and pop it in bottom of my 80 ltr plastic bin i got from Wilko`s.

I`d prolly hold off from feeding those again till roots kick back into life and come round from cold or they will just carry on locking out ferts, which could take 4 to 5 days or more, but that will give ya time to get a heater for rezz. Those look fair sized pots and they prolly only need flooding once a day till they really come round. Set heater in a big tank around 22/23c and use an airstone or summink to keep the ferts in your tank moving, summink like an airstone pump and a bit of air hose in your fert mix without the airstone on end (flooming) which is prolly better option id go for personally. stick it lower down in your tank so it spread's heat around from pump and it should heat the tank up steady and even to around set heater temp

Also raising or lowering humidity whichever that maybe during veg to between 50 and 65 rh should help with uptake a bit more so long as room temps aren`t too low or high

Yes they all look be suffering same problem from what i can make out, well to my eyes they do >>> cold wet soggy roots causing it.
