Think i have some deficiency maybe Mag ? yellowing of predominantly new growth areas (see 5th photo)
tried a foliar spray and water in with Epsom salt 0.1 g/l ~ 200ml for each plant we will see if that helps
also added some Pacific Natural Fish Hydrolysate (2-3-0) 1 l @ 1:100

Light cloudy green areas between veinsHi,
Two of my plants (3rd week of veg) have these symptoms on the middle level fan leaves (the biggest ones). Young growth looks ok. Doesn't look like anything in symptoms photos, closest thing is magnesium deficiency. What do You think it could be?Week 2

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!4y ago

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!6y ago

Hi, im having some troubles with this little girl, there is this yelowing around the edges on some random fan leaves and smaller bottom leaves. I am not sure what is wrong since all the other plants are growing well under same conditions. Could it be magnesium deficiency?Week 4

I did mention in my comment that I water about 800 Ml twice per day split between 6 plants in the 1 large pot and can notice quite a few of the plants have slight yellowing. So not sure if this is a watering issue or nutrient problem or normal.Week 2

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?5y ago

Please help identify the cause, interveinal chlorosis since 2 weeks old, no necrosis so far. These two plants are 26 days old. Do they look stunned?Is this magnesium def since it's going from the bottom? Is it possible the first signs started to show when they were just 2 weeks old? Or is this iron? Or is it smth else? Calmag given two days ago. Pistils show already. I water with ph6.2 but no runoff yet to know the soil ph.Leaves. Veins - yellow between

Deficiency?What is causing this deficiency? UsingProMix HP, top dressed with worm castings, and foliar spray with Epsom salts. I think it is Fe/Mn/Zn deficiency that looks like magnesium deficiency, and it seems to happen to all the plants at about this age. Mega Crop and kelp to fix?Week 4

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.Leaves.
