They look really small for 4 weeks. I hate tossing things. I would wait and see if they pick up or if they start flowering soon u can toss them.

Yeah the other option is throw them in the flower tent and walk away and plant a few new ones.

Wait your title says almost week 4. So it’s 3 weeks old? I would give it some more time. That’s just my 2 cents

My 12 day old ones are bigger than that only thing I can think of is iva lack of nutes or crap soil lack of water. What is it your growing in.

just like title, these things seem to be growing hella slow.

A little overwatered, wprking on that, but at most week 4 shouldn't they be bigger then this?

Hlg 100 v2 light 4x3 space temps 78- 86, rh 50-60

Crappy seeds should i toss em and start new autos?
Need a little more info. Type of water? Ph? Light height? Size of pots? Etc etc etc. The more information you provide, the better the help will be. No matter how insignificant it may seem, add it in there. Sometimes the little things end up being the main culprit.

Have you checked your city water logistics? Sometimes depending on where you live, city water is bad, I know it is where I live, I have to use calmag which typically isn’t necessary when using tap water. Also, while I understand you are using Big Rootz, I’m interested in knowing what the NPK ratios are. It’s not listed on the bag or the site, at least from what I’ve seen. Very important information to consider. 4 weeks into the grow, I’m sure they are starting to get hungry, but without knowing what the NPK ratios are, it’s hard to narrow anything down. It says the soil is ph adjusted, so apparently ph’ing your water isn’t a concern, although I would do it anyway.

Copy, I may have to get an analysis done.

Today they seemed happier, will just let em go i guess, shrug. Not like the space is ultra premium needed at the moment.

Those NPK ratios aren’t gonna cut it. They are extremely low. My nitrogen ( N ) is an 8, and that’s about as low as I’m willing to go during veg, and you are at .3. P and K needs to be boosted significantly during flower, and you are at .3 and .5. My P and K ratios are 15-17. I would suggest either getting some liquid Nutes, or amendments. Those girls pretty much starving right now.

Ugh, well that's yuck. Guess its back to ffof for me.

So you run 8-15-17?

Guess its time for me to do some researching. Was hopi g to avoid having g to use nutrients, but looks like its unavoidable.

So, should I supplement the water with every feeding with a 6-4-4 (see attached, I like the fox farm ones, but honestly open to cheaper alternatives).

Not necessarily, I run 8-3-3 during veg. During flower I completely cut the nitrogen and run 0-15-17. If the plant wants Nitrogen, I let it feed on its self to get it. But I grow organically. My amendments aren’t that high in P and K, so I have to supplement with kelp and guano to reach the desired levels of P and K that I’m looking for. When I choose to bottle feed, I use the FF trio. ( grow big, big bloom and tiger ) My soil is promix hp, whether I bottle feed or use amendments. Coco is a whole other beast. Other than that, I use calmag and blackstrap molasses ( unsulphured ). And that’s about it. Always ph to 6.5-7. Never really have issues or deficiencies.
