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.

Interveinal chlorosis and dead spots on leaves, deficiency?This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Help, what are those weird yellow spots in late veg?Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid.
Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

Can anyone tell what is causing these yellow tips on new growth on this plant?I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Sligthtly Yellow LeavesI'm growing 2 Mephisto Canna Cheese seeds. Canna #1 is looking very healthy and green. Canna #2 is healthy (ish) but its branches are more spread out and the leaves are a bit yellow green. I'm trying to figure out if I have a problem with Canna #2 before it gets worse.

Should I cut off yellow leaves?Bulldog cookies, 5-6 weeks in flowering. The leaves started yellowing, not fast like a disease or something. I'm thinking about cutting them off. should I? Would it be better for bud development, or in this flowering stage is would be too much stress?
