Do I need to add more cal-mag? What are the spots on the leaves?
RedEyes34started grow question 4 years ago
My plants are getting some weird spots and looking very light colored and droopy. I haven’t gave any nutes yet cuz I’m using Fox Farms Ocean Forest soil and I’m PPM of the soil is just now getting low so I was going to add nutes the next feeding. Do they need more cal-mag?

Looks like a calcium deifeincy. First thing to do though is to check your run off PH . If it's massively out that means some nutes aren't getting used . As they'll only be absorbed at certain pH levels .
If your pH is fine and you don't suspect a lockout issue. Then feed some more calmag . I like calmag plus , as it has some iron in it .

Hello,
Your plants look droopy which is a sign of overwatering also the brown spots on the leaves seem to me that it could be a pH issue. Double check your pH pen and always have it calibrated. How much Calmag are you feeding it now and how often? If it’s low up it an ML or two, see how she reacts. Cheers! 🌱

I have only gave Cal-Mag once and at 1/4 strength to the Bruce banner plants. The Massassin with the tiny spots all over the leaf hasn’t had any Cal-Mag yet.

Brown spots are signs of calcium deficiency. What is your ph/ EC coming out? If you are already adding calcium magnesium you might be having a lockout of nutrients. Personally I’ll flush my plants to 200-300 ec then give them a feeding right after I flush and let dry for a few day then then continue with there regular feeding schedule. Hope that helps

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?

Are CBD-Strains less nutrient-hungry?Hey Guys, i experienced that these strains like a lower EC/TDS. Every time i went over 1.2 EC (600ppm TDS) they showed signs of over-nutrition, like very dark green leaves and reddish brown leavetips. What are your thoughts on this? Are CBD-Strains less hungry on nutrients?

Stresst es Pflanzen sehr, wechseln von LED zu SonneIch wollte mal fragen ob jemand Erfahrungen gemacht hat seine Pflanzen bei schönem Wetter raus zu stellen und bei normalem ins Zelt unter LED. Gibt es da negative oder positive Erfahrungen von euch? Ich habe ca.65k lumen unter der LED und die Sonne bringt es so auf 120k lumen...

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?
