I grow autos. What do you feel the trouble is? I see cupping. Maybe mg deficiency but I can't tell from the yellow'ish color of the photos. (Can you take photos in natural light, or change your camera's setting to compensate for the warm light?).

Cupping can accompany mg def, but more likely heat stress.

What is your soil, nutrients, water (tap or RO), temperatures, and ph of what you pour in and runoff?

If you look at my other threads there is alotof of pictures of whole grow room. My nutes are I organic blood meal, unsulferised molasses, And super thrive. Do I need something else? Also I'm using 70% perlite with 25% miracle grow organic potting soil, And 5% vermiculite. 3 gallon pots. I've been watering every other day with nutes on alternate days. Also my lights are 4 26 watt cfl, and one 100 watt hps. I lst today.

Here is my NL Auto 6 weeks old. 150 w hps. 100 w cfl.. Everything seems ok from your description except she is not putting on any size. My first plant was a bum seed. Never got taller than 8 inches. Just bad genetics. Maybe start over, but use more soil next time.. Just a thought.

Sunny gave good advice. I'd also say MiracleGro doesn't get a lot of love among MJ growers, especially the soils. Was your choice of soil and nutes because you want to be organic?

Yes I was attempting organic.
I haven't grown organic so I can't offer alternatives on your soil, or observations about your nutes. If your a newbie, it seems to me like organic would be more challenging than getting 1-2 more controllable synthetic grows under your belt.

If you consider a non-organic grow, I'd recommend Pro-Mix HP (with 25% perlite added), 1-2 Tbsp dolomite, and Gen. Hydro Flora Series (3-part) following the so-called "useless" schedule. (<<link). You can supplement with some bio/organic things.

Not trying to steer you away from organic. Maybe someone with experience can guide you through where you're at. Just saying there are "step by step" ways to grow that give you more immediate feedback. That direct control can be daunting. But, IMO, not as much as the uncertainty of waiting to know if the organic "brew" is correct. I admire people with the talent. But, as a new grower, I felt like the synthetic route was like "guardrails" on my first grows. Follow the steps and, it pretty much works. Cookie cutter. After a few of those, you start thinking "can I do better" and ....

Thanks I just added a new post do you have any experience in hydroponic? What about cfl?
Nope, neither. I've used T5HO on an autoflower with 2 CFLs on the sides. I felt like T5HO was good for vegging, and flowering shorter plants like SCROG or autos. Not good in flower with taller (untrained) photosensitives. I imagine CFLs suffer worse, but have the upside of more uniform distribution.

I use LED now. It's an imperfect world too.

seems like you are using boosters and not real nutes. you need nutes first. molasses is good for a carb boost while into flower. superthrive is a good vitamin boost but not a real nute.miracle grow has a broad variety of mediums but some drain too fast while others retain moisture to the point of growing algae. make sure it is one somewhere in the middle. looks like too much water not proper nutes to me. been awhile but im sure ive been there . it takes a lot of b meal to get the n you need. good luck

Add reflectors to your CFLs? Keep an eye out for a good deal on a T5HO fixture? Autos being smaller, you can do pretty good with T5HO and CFLs (if you're in a cooler climate and don't have to worry about the heat produced).

And any advice on nutes?
You mean nutes for your current soil? I'm not too familiar with organic nutrients. If I was trying to get by on the cheap, I'd buy Alaska Fish, Alaska MoreBloom and Alaska Kelp. They're at consumer garden centers like at Home Depot. The fish will stink things up.

You'd have to google for those product names to see how people use them. Usually half-strength is a safe starting place for anything.

First, is that your only seed if it was you can't tell if it was the seed
or environment a 6 wk. NL should look just like Sunny's (nice job,
cu do's to Sunny747) I would flush with plenty of plain water then
let it dry out well before you get radical.
Next get more seeds and new soil, try guano tea after 3rd wk.
of flowering but be frugal don't over feed!

My bad, I missed the 70%, no you can't over water but I would lose the MG soil
I use Wonder Soil which isn't soil it is a coir blend works well, anyway back to
Reo, Sunny may have a valid point try another seed.

I just went with a soil that people recommended. Come to think of it, the seed that I had that never really took off and turned out to be dirt weed was grown in Scotts Super Soil and MG Perlite. I wouldn't say that a nice plant couldn't be grown in MG products, but I found that I couldn't control the situation because I didn't really know what was in the soil. Some of the nutes are time released. Now I have flowers and vegetables growing in the Scotts. They seem fine.
