iHigh Posted August 9, 2019 Share Posted August 9, 2019 So I spotted this on one of my plants, and though it was isolated incident and was not to worried. Now I see it is happening on a few more plants. I am using Atami buffered coco, with GH FloraCoco nutes. Anyone recognize this please ?

SneakyDave Posted August 9, 2019 Share Posted August 9, 2019 Sup yo what's the ph of your water? I noticed my plant did something similar they got dry and crispy like that when the ph was to low and it happened on the lower older leaves the new growth seemed fine all I did was up my ph to 6 and it stopped 1 Quote Link to comment Share on other sites More sharing options...
Bos Posted August 9, 2019 Share Posted August 9, 2019 My outdoor showed similar progressive browning/necrosis from the centre of the leaf. Mine identified as a calcium deficiency, I treated it as such. With indoor could be ph related/lockout or just plain deficiency.Sent from my SM-G900F using Tapatalk 1 1 Quote Link to comment Share on other sites More sharing options...
CreX Posted August 9, 2019 Share Posted August 9, 2019 Yea... Slap them with a good dose of calmag if you have... Or Epsom salts at the least... I wouldn't say so much a calcium def... More magnesium... That's the brown rust spots... Dead giveaway... Dose them and they will be right in no time... The damaged leaves will never heal or come right 1 2 Quote Link to comment Share on other sites More sharing options...
iHigh Posted August 9, 2019 Author Share Posted August 9, 2019 Thanks all - definitely Cal/mag issues. I though that using the Atami coco which is buffered, and FloraCoco which I presumed would be adjusted for Cal?mag in coco would be okay, but will dose them from now. Removed all dead leaves. Thanks 3 Quote Link to comment Share on other sites More sharing options...
