Hello all, I am currently growing a mephisto strain and one from fast buds. So far all of my fastbuds came out great however this mephisto (which is fed the same as the fast buds) looks to be dying and I was curious if you guys could help me figure out why. The fast bud plant is the one that looks healthy. I PH the water to 6.0-6.5, but what could I be missing nutrient wise? I use liquid gold leaf fertilizer for all my harvests and they’ve all came out 10/10
Help, i havent had this happen before

Oh shoot my bad i thought they uploaded let me try again. I grow in coco loco from fox farm, i use the SF 4x2 kit with gold leaf liquid fertiziler as my nutes.

They might be too big .

At first glance it looks like overwater. Have you allowed the soil to dry or do you use a moisture meter prior to watering? (Checking each plant not just one?)
Recently had 2 youngsters stopped growing and leaves hanging about a week or 10 days after up pot to 1 gal pots. Did a flush and found ph runoff over 7. Put in 5 gal pots with different mix and they both came back happy and growing again. Usually when I'm stumped I flush very slowly until I get enough runoff to check ph and ppm and go from there. In my case it was self inflicted as my mix tested low ph so I added lime and suppose I overdid that and drove ph high. Plants looked underwatered. Then i read high soil ph can cause roots to not take up water and eventually damage them if not corrected. Look at everything. When did it start being sad? What changed? Is ph pen trustworthy and calibrated? Using municipal water? If so, check to see if they use chloramine (fatal to plants). Hope you nail the culprit soon.
I use the kit from general hydroponics, it first started looking sad when i first initially fed it my nutes. i have also been having humidity fluctuations due to the winter season, but my humidifer has balanced it out. Other than that I'm on my 3rd grow and I've been doing the same thing I have w th eother plants (fast bud genetics) but when I buy mephisto this happens. I spoke to my grow store about it and they said it look like a Mag deficiency
I'd water to runoff with 6.4-6.5, measuring runoff ph and ppm to get an idea what's going on in the root zone for starters. A friend overfed with the flora trio. Runoff was 2500-3000 if memory serves. Several gallons of flush got it under control (under 1000) and he finally stopped using the aggressive schedule. A major flush tends to strip more Nitrogen than other elements as it releases the easiest or so I've read. Going a little heavy on micro afterwards in the next few feeds will help restore the lost N.

Too dry buddy! All those pale green leaves at the bottom will die and go necrotic now.
It also seems too high in N as well.
So the plant probably couldn’t cope with the high EC media and grew slowly compared to the others.
Any recom
ahhh any recommendations?

Underwater can appear just like overwater
Hopefully you have watered since photo if it was truly dry.
Different genetics definitely act differently. As you have now learned(lol). I know it can be frustrating to have done nothing different and received different results.
What's your room temps, humidity/VPD? I agree with VaSmile that looking at the stems and leaves I don't really see a deficiency. What I see is either your VPD and soil humidy is too high or too low. As someone else said over and under watering can look similar. Looks like the stomata and the leafs are closing up to protect itself, and that usually happens when enviromental factors along with watering are out of balance. I've seen something similar from being cooked by a light to close also. If at lights off your VPD is dropping under 0.8 your plants wont transpire and you will not get good dryback. Same if you have extreme VPD during lights on. The plants are over transpiring and will close up to protect against that. Just something else to check. Adding nutrients will do nothing (good) if the plant isn't able to uptake.
