This is an old question sorry. Brother your plants look fine. Loosing a few of the oldest lower fan leaves is perfectly normal.

My opinion it was cuz the leaves weren't receiving enough light to stay green. You probably know by now. Hope this helps and keep growing

Nitrogen is one of the most important then potassium and also magnesium in proper dosage i only see your using bloom A now you want to introduce sea weed extract or piranha/tarantula/voodoo juice

if you need recipe for brewing your own tea let me know

Take it she’s doing better? Lols better from the photos?

That’s a Mag deficiency, add cal mag on each watering BUT if you overwatered the roots they cant absorb nutrients and your plant will show deficiencies.
ONLY WATER WHEN THE POT FEEL LIGHT, AND DONT WAIT UNTIL SHE DROOPS.

Cheers my friend

Hey here GreenAckers, I actually disagree with the others on this one : you have magnesium deficiency you can tell from the yellowing between the veins and the oldest leafs being affected first. Magnesium is used to regulate photosynthesis and metabolism ( when the plant gets hot ) so the combination of the 18hr light schedule which is intense for a plant plus the fairly high temperature kicked the metabolism into overdrive and the plant cant find enough magnesium quick enough. To fix this it's quite easy add cal mag to your feed and make a foliar spray with 3-5ml/L and spray two or three times a week and it should recover within ten days. Never grow without cal mag ! hope this helps ! :rocket:

@GreenAckers Hard to see with the lights on but the soil looks a little wet and perhaps your Ph is out and she can't get the nutes she needs. What ph are you watering at? should be 6.2.6.5 also 30 celcius is quite high can you bring that down at all? Hope this helps mate

hi greenackers, your plant requires nitrogen that's all. Start introducing some Veg nutrients to your plants and you'll see this stop within a week. Whatever was in your soil is now depleted.
