GrowersParadisestarted grow question 3y ago
Still have an issue. No pests that I’ve seen, Cal didn’t fix it, flushed res, lowered EC to half strength, problem continues. Temp 75 RH 50-60% PH stable at 5.8. I’m Stumped. Could it be my well/tap water? Spots are very dry/brittle

@braveheart, PH has been stable at 5.8-5.9 on the blue lab controller, very rarely doses tbh. I’m not so sure, UNLESS, it’s tap water related and the hard water is causing some unknown issue.
@hashy, I’ll give these suggestions a shot

Hi. Increase your hydroguard to 0.4ml/L. Increase your calmag to 0.5ml/L. Leave the rest as is and see if that stops it getting worse. Damage can't be fixed on old growth.

Looked into that possibility as well, one reason I flushed and added back half strength EC. Not so sure but I’ll consider it, I appreciate the answer. Stay tuned. Will give it a few more days.

Hi, so I'm going to be dropping my seeds soon and have been doing my homework on common problems that might come up. Looking back I remember seeing something and luckily I bookmark everything that's worth holding onto. So, t could be phousphorus issue, take a look at number 5 of the list of most 12 common leaf issues. Hope this helps https://budverde.com/marijuana-leaf-problems/

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

Wet shiny spots on leaves.I find occasionally such wet shiny spots on leaves. Any idea what the root cause and how to fix it?
They are not sticky although look like.
I cannot say whether they smell because smell of the leaf is too strong 😶
I can rub them off with the thumb with no sign

Stains on the plantHey guys,
first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

Insects, Mutation or related to my early nutrient burn ?Hey I noticed that one leave is looking like it has been eaten by something.. I checked every plant and also used yellow stickers, but can’t seem to find anything.
Is this related to insects or could it be something else ? (The plant had an early nutrient burn, but recovered)

Brown spots on top leaves - nutrients, light or something else?She went into flower, now stretching. Set light to 100%, added Bio-Bizz Top-Max and Bio-Bloom (1ml/L each).
3 days later brown spots appeared on top fan leaves, very few also on lower fan leaves.
I suspect this could be light burn or nutrient related.
Any ideas? Pls help
