Your advice needed. Nute problem?

[Posted in wrong forum. Reposted here]



Hi. First post for a first time grower! Been lurking for great info, but this problem perplexes me.

I’ve got an outdoor grow in Vigorous organic soil. Wanted to go TOTALLY ORGANIC, so I’ve only used worm castings. Nothing else has touched this plant except water. (No extra nutes, sprays, or anything). Adjusting pH of water to 6.5. Sampled runoff and it’s at pH of 8.1. Plant is in about week 3 of flowering stage.

*Anyway.......... The tips of the larger fan leaves have burned and are curling under. The plant went from the typical olive green to a lighter spring green. (Hoping photo shows up on this post...I’m old!)

TBH, I think I underwatered her. I’d heard the biggest mistake for a noob is overwatering, so I backed off a bit too much.
Have since watered them twice with pH of 5.8, to try to bring soil pH down.
I need things to be as ‘perfect’ as I can get it.
Love the science of this process.

If it were Nitrogen burn, the leaf would be a darker green, I think.

Could the leaf symptoms be from UNDERWATERING, or is there a better explanation?
Wow! I just doubled my knowledge of cultivating in the last five minutes! Thanks. I’ve been watering with regular tap water, after letting it stand for a day, and then pH correcting it from about 7.5 to 6.5. The ONLY thing that has touched these plants are water and worm castings. I used the tomato cages for supporting and separating stems. I’ve been pruning the sickly stuff off of them. (That’s why there’s no burnt tips on any) Thanks.

Looks far better than the palm tree....LOL.

I see no problem. They look good. They will lighten up in color (buds will have the most hues/color) and you will see the bigger/older leaves yellow...this is natural. You already know to just take that shit off...

I'd just keep going....yer doin fine...no stress...no worries. Just ride it out and be patient enough to truly let em finish and all will be golden.

be well!

you have micronutrient deficiencies. EWC is very good fertilizer, but it's not complete. you need to mix in a few other things to get all the micros your plant needs. i'd add some alfalfa meal, some kelp meal, and some insect frass or crab meal.
the alfalfa and kelp meal will take care of all the micros you need, and the insect or crab meal will both add micros and activate the plants immune system

Wow. That’s great. Thanks. I enjoy learning this. Not sure what EWC means. Where would I source alfalfa meal,.... etc? Does it come in a combo bag at a grow store, or separately at a farming store?
Cheers.

EWC is Earth Worm Castings.
a lot of grow shops and garden centers may have alfalfa and kelp meal, i just get it off of amazon, prices are fairly reasonable and it gets delivered to my house.
if i top dress with it, i just scatter a couple of spoonfuls around, then scratch it into the surface. if you leave it lying on top of the soil, it'll mold. it doesn't really hurt anything i guess, but if you mix it into the soil a little, it won't.

EWS= Earth Worm Castings. . Sorry, Dude. I should’ve guessed that!

I went to my local, Canadian grow shop and the proprietor was very knowledgeable. Sold me a quart (liter) of CalMag Plus. Said it should rectify my nutrient deficiencies.
I’ll definitely ensure that they don’t dry out again.

Lookin good. I would get some garden tape and support some of those branches..

I’ve been keeping an eye on them lately. I put the tomato cages in to help separate the stems early on, and will use them to support the heaviness in the fruitful weeks to come!
First time growing, so I thought it might be helpful to instal the cages. They seem to have been a good idea!

Your ladies look fine. If the plants lighten in color after the stretch it’s usually due to lack of available nitrogen for the plant and that can be fixed very easily.

I’m no a masta growah but that’s just my experience.

well, it probably won't hurt, but i don't think you have calcium or magnesium deficiency. and if you want to stay totally organic, using cal-mag isn't the way to go.

Sorry, I meant EWC, not EWS.
