Any ideas as to what might be occurring?

i have two fairly young plants growing right now; green crack and blackberry kush growing underneath two 300-w led lights. Probably about 3-4 weeks into it. I'd like to think I'm not overwatering in the least and I just started using nutrients very sparingly (I've used one 16 ounce bottle with approximately 1 ml of each organic nutrient and have been using a spray bottle to give my plants nutes, I haven't even used up that whole bottle yet).


The green crack seemingly drinks up way more water than the blackberry kush. I basically just keep the soil damp with a spray bottle 2-3 times a day (usually less than twice a day for the blackberry kush.)

I raised the lights up tonight since I feel like I haven't overwatered and definitely haven't been giving much of any nutrients, but I'm open to every, any, and all critiques.

Thanks in advance to he saint hat helps me.

The first photo shown is the blackberry kush
The second is the green crack (I'm also growing in 5 gallon buckets)

Lessen the nutes dude they’re young! What soil are they in? The second pic I’m talking about btw

if you add water daily you are overwatering.
soak soil completely, let drain/dry, then water again.
pick a feeding schedule and stick to it, no guessing.
stop spraying, start growing.!

Yeah leave a gap until soil is DRY! Can’t go wrong with that! Also the soil will contain nutes so stop using the bottled nutes until plants are larger! Especially the 2nd picture and use less!!

That bottom picture, the plant is very small for that pot and I see its wet from edge to edge. There is no way that plant needs that much water, and you are nuting which it most certainly wont need in a pot that size for awhile. Unlesd youve used it before and flushed hard at a harvest. People i know are mixed on stepping up in pot size. Ease it up a little on the water and nutes on that one for awhile let it dry out. Watering edge to edge where no roots are will lead to a build up.

Agreed! Water around the stem in small amounts!!

no, add water to the pot in one dump. the roots travel for nutrients, which are made through the whole pot when organics break down ideally. wetting just the stem area does not allow the dry areas to compost. you'd be better watering an area furthest away from the stem if you need to be different. roots find water but they dont like to be drowned in it. too much water makes for less 02, root rot, no fungal activity, dying beneficial organisms, dying soil web, slow growth, dead plants. growweedeasycom

the second plant is way too small to be getting nutes and have soil moistened/misted everyday multiple times a day, wait till soil drys out almost completely till next watering stick your finger in the dirt if you cant go 1-1 1/2 and inch without touching moisture its time to water you want those roots to search for water they will find it wherever it is trust me.

One dump?? If anything be better to lightly water around the edges of the pot after letting it dry out completely, either way water less dude.

seriously, we completely wet the soil, all parts within the container become moist all at once and we allow for constant drainage. The drainage pulls fresh air into the pot from the top as it settles to the bottom. when the bottom becomes drier we repeat the process for great success( for the few thousands of years I've read about the cultivation of cannabis)
The result is 100% of the soil is cooking all at once. The fungal web goes from end to end inside the pot(instead of little wet areas?) 100% of organic material inside becomes available to the plants roots on demand as its broken down by all of the aerobic activity within. We water, we see run off amounts, we gauge the amount of water to reduce wasted resources from the run off. All beneficial organisms are colonizing all of the soil. There are never dead spots, places with no beneficial organisms, root activity, etc. Watering any other way is not taking advantage of the root zone and its potential capacity of unending resources it can provide. A plant will grow with minimal resources like a houseplant does, but we demand more than a plant from our flowers.

I'm not arguing only educating amigo.

This would be an ok option if the soil isn’t rich and didn’t have lots of slow release nutes which appears to be the problem, telling the guy to do that will worsen the problem, I see your thinking and I agree to an extent bro but given the situation not a good idea, if replacing the soil with a lighter mix then jobs a gooden.

Thanks so much everybody for all the responses. I'm going to try and condense the responses I've gotten from all of you into this reply.

I've taken the general idea of a watering schedule as opposed to free styling it with misting the soil twice a day. That makes sense currently. When I grew outdoors this is what I did with the plants without any issues. But I think the strains I used outdoors were just rugged as hell, so it makes sense that I didn't screw anything up in hindsight haha. And waiting for it to completely dry. I'm holding back on the nutrients as well.

I will say, that that little plant drinks significantly more water than that bigger plant. (I anticipate watering the bigger plant 1/2 the amount that the little one will require). And the age old idea "less is more" seems to trump in the realm of growing cannabis. Notes taken.


I do have another question for you guys. I read up on green crack. It sounds like it's more flexible with growing (thus easier?). But that it's susceptible to powdery mildew.

Aside from the fact that I didn't think this through and will be getting a ventilation system for the grow tent; there seems to be a lot of confusion around preventative measures (and just a general lack of information in struggling to find).


It sounds like low temperature/high humidity is a breeding grounds for powdery mildew, but just as much as not having ventilation.


Any suggestions in taking preventative measures for powdery mildew? My humidity right now stays at a consistent 70% with an average temp of about 75 degrees and no ventilation (which I now realize is an incredibly n00bish mistake to make). I plan on cleaning the tent out tonight and airing it out. And have read about lecithin sprays as preventative measures.

70% is not all that bad in the veg stage, it WILL need to be lowered for flower though to between 40-55% and maybe even 30% in late flower, yeah man defo get the temp up and maybe lower the humidity 5-10% if you can! You should be good!

So I've given this plant two feedings. The first week after reaching out to this forum was a 1/4 gallon of water. (I waited for the soil to be ultra dry. The second week was a half gallon. No nutrients

The first photo is to show you all the tips of the top leaves. They appear to be yellow.

I believe the second photo is of the middle leaves of the plant and the last photo is a close up of the ultra yellowing leaves.

Haha. I'm hoping this isn't bud rot. Any ideas what might be occurring now?

Can’t be budrot without any buds dude haha, the yellowy/lighter growth in the top pic is normal, it’s your bud sites dude, the rusting on the fan leaves could be a couple of different things like calcium def, are you feeding micronutrients?

Hah. So sorry I meant root rot.

I haven't given that plant any nutrients for a few weeks. Definitely not calcium outside of a few light feedings I gave the plant approximately 3 weeks ago

Ahh I’d give her a bit of a feed bro. Some micronutrients with that also!

I just watered it on early Thursday morning. Should I wait for the soil to dry up before giving it some nutes?

Check the soil tomorrow and judge man, still moist? Do it Monday! How much water are you feeding per feed? (In litres preferably)

Sounds like a plan. Thank you so much for the feedback. I'm giving it approximately 1.8 liters
