My guess would be PH and or magnesium. 5.8-5.9 in veg. 6.2-6.3 in flower. Good Luck!

Roots getting brown
My Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!

PH Fluctuations and/or Nutrient Issues?
I'm Running a Recirculating Deep Water Culture System( hydro). Had PH dropping dramatically a few days back but did a full water change and everything has stabilized. Just Flipped to a 12/12. Does it look like that was the issue or is it nutrient toxicity/deficiency. Or Stress?

Yellowing between veins on 3 of 4 plants, and curled tips - 27-29C in tent - Just heat/light stress or something more?
Only on 3 out of 4 of my girls, see 1 pic of sad girl and 1 pic of happy girl. Does it look like heat/light stress to you or something more? I was running my LED 45 cm below the lights dimmed to provide 20-30k lux at plant level. Just now raised to 65cm, lux 20k.

Leaves Showing yellow edges and banding
Is yellowing of leaves and dark leaves toxicity? no curling . moved the lights further away. I'm growing organic. The plants look stunted short dense. I've only got a cheap pH meter calibrated. 🤞 use RO water pH- citric acid. Overall they are short dense growth wise

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.
Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

What does this stress look like? PH lockout? Overwater? Natural Fade?
I overwatered. Did 4 litres into the pot. Then did another 1.5L the day after (in a 7Gal cloth pot) I think this caused overwatering toxicity. Does the strees look like: Water Toxicity? PH Lockout? Or fade from entering in the latter half of flower? Buds getting bigger still.

Possible light stress?
Any help would be much appreciated, so the leaves are looking with a yellow tinge , my thoughts were light stress as had lights on 24/7 on to high and to close I have since then back off on the power of the lights and move them further away from the plants and changed to 20/4.

The ph value is 6.3.👍 Yesterday I poured Short Flowering Powder "0.5g / 1.5l" in ph 6.28 water and today I notice these yellow spots. The beauty has grown 5 cm since yesterday.💪 What could that be? I'm just a bit worried?! 😲

Yellow veins
Hello growers, my girls have these yellow veins on the leaves, could it be a slightly too low pH and the consequent deficiency of magnesium? How can I act? Can some Epsom salt help? Thanks

PLEASE HELP!!! CalMag deficency?
CalMag deficency? Deficency starts on lowest fan leaves. Starts as a shiny spot in between veins that later turns yellow, eventually spreading to whole leaf causing it to die. Uping CalMag in feed and spraying her with CalMag water mix. She responds well at first then spreads.

Help. White widow Auto day 7
I am curious about this white widow auto seedling. This is day 7. Seems to be losing a little color, but is still growing faster than the other 2 seedlings I dropped. Any suggestions on this? I have only been watering with distilled water. I have not fed any nutrients yet

Leaf fade vs. deficiency
Hey everyone, does this look like a deficiency? I’m in week 6 of flower, I had half a week of high temperatures and I’m sure she was affected just a bit and noticed Bud growth slowed slightly. Not sure that influenced this and if it’s a deficiency(magnesium?) or normal leaf fade.
