Fast-growers starting to show issues.
the_canna_scientiststarted grow question 4 years ago
Got some issues on these fast growers. I've been treating it as a cal-mag deficiency, however I've been feeding calmag for two weeks and its only getting worse it seems. Any thoughts? PH is 6.0-6.3, PPM 444 feed, RH 47-50%, Temp 77-81f.

Hey bro. Did your problems start after the plants got bigger? Were the spots half way up and near top? When those fabric planters it hard to get all the root system wet so when they fill with roots and you see your feed coming out the sides it is leaving dry spots in the root zone. Dont need much cal/mg in soil so you may want to flush and refeed. Maybe a little higher than you were and leve the cal/mg out of the pic, unless your new growth sys it needs it. Hope this help. Cheers friend

gmslave, that is exactly it. Only once they grew 30 inches in 2 weeks. Middle of the way up. The new growth looks fine, but it's only when the plant ages, I am currently watering 2400ml in 11000ml pots. I was reading your other posts about this and was thinking this was happening to me as well. I'm preparing a flush now and make sure I saturate everything from here on out. Thanks.

Is my plant showing signs of Nitrogen deficiency?Autoflower, day 40. Most leaves are in a yellowish-green tone or even completely yellow. I was mistakenly watering it with tap water, but when I noticed the yellowing, 1 week ago, I started watering with mineral water at pH 6.49.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8

What’s with this Odd growth rate and leaf patternStunted growth on 16 day old northern lights auto. 1/3 coco 2/3 fox farms ocean floor.
gave it a minor dose of cal mag plus just in case this is a developing deficiency. It has three nodes but it is very small at approximately 1.5-2 inches. The pattern may be genetic?

What's the problem?Hi guys, basically for the last few days the problem hasn't varied too much but I can't figure out if it's my light or if it's coming from somewhere else. Some of my leaves are curling with stains either on the leaf or like a burn on the tips.
