Crispy Yellow Leaves
MediciGradestarted grow question 6y ago
Inflow EC=1333 w/ PH=5.8 vs Runoff EC=658 w/ PH=6.0. Insufficient nutes due to light intensity? Perhaps my PH meter is inaccurate? Light is 42 inches from canopy or ~600 PPFD. RH 65%, Temp 80 F.

everyone says 5.5-6.0, but unless your fertilizer says so, you should more likely stick to 6-6.5.

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?

Yellow centre veins fan leavesYellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?

Discolouration progressingThe first pic is from 2 days ago, now the yellow has turned to brown spots and is beginning to spread to others. I'm hoping it's an easily corrected nutrient imbalance, please help

Magnesium - Nutrient problemDo I have Magnesium deficits or any other problem? I started to notice during the last week and it is progressing quickly.
The last weeks, pH of drain water was low (between 5,5 and 5,8) but I could increase it until 6.1.
Has anyone the same problem?
Thanks!

Also a 1/16tsp of bud explosion and sweet candy. Should I add more? I have the whole line of fox farm nutrients. Anything from there that would help?

PLEASE HELP! See former question as well.Continue to see deficency or burn in leaves. I have fed her only ph water for 2 weeks and it continues. I asked for help before, everyone just tells me what they think is wrong and not the reasons why. If you have an answer it would be appreciated to know your reasoning. Thanks🤘

Leaf fade vs. deficiencyHey 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.

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?

Roots getting brownMy 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!

Strange coloured fan leaves (3) on one of my 4 plants, maybe some sort of deficiency? Thanks people!Hey there smart people! I have about 3 strange coloured fan leaves on one of my 4 plants and I’m not really sure what to make of it. To me it doesn’t look like any deficiencies that I came across per say. All other leaves look nice and healthy. Kinda randomly scattered. THX!
