Stunted plants.

[Foster]

k I’m currently growing 3 Photos pink kush, Purple punch, gg4 . Two and 3 of them had very little growth after transplanting. Colton 5 gallon fabric pots. One With happy frog and the other with root organic. They are on day 40 and I want to flower soon just trying to figure out what the issues are. I Transplanted to weeks ago. I’m using Advanced nutrient, sensei grow line and have started feeding at have strength. I water/feed when the top is dried out a few inches. The pot feels bottom heavy. I think I covered everything. If anyone has any suggestions, I’d love to hear them.

Lights?
PH?
RH?
temps?
indoor outdoor?
Pics of the plants!
Root damage from transplanting?
which plants are in what soil?
Are pots light before watering?
Water/feed schedule?

If you provide the info Rwise asks, the knowledgeable growers on this forum can provide suggestions.
And pictures are important both for diagnosis and just for the fun of bud porn! Let's see them girls!

Did the plants have a "nice intact root ball" during transplant? Maybe just water around the transplant and not the whole pot..Might want to mix some diluted nutes up in sprayer and help them out that way.

My bad. This is an indoor grow in 4x4. 18hrs of light. Light is mars hydro fc 4000 at 70% power. 76-80 degrees at 50-55 rh. Transplanted from solo cup to 1gal to final 5gal. Transplanting went smooth, and the plants all had nice roots. I feed them every 3-4 days ph 6-6.5 . The top of the soil dry 3-4” but bottom heavy if that makes any sense. The first pick is happy, frog soil. The second pic shows all three including the one that’s growing fine. The last pic is root organic soil, and the larger plant is also in roots organic. I I have had a light nute mix. I feel like I’m over watering them but again they’re so dry to top. Not sure this is my first indoor grow. I’m using advanced nutrient Sense they grow. I’m not sure why the pics didn’t go through the first time hopefully they will this time.

I have mostly used Ocean Forest and Big Rootz soils and I had similar issues with top of soil being dry on top and still pretty moist and heavy on bottom (I use plastic plant warrior pots). Those auto flowers grew more slowly than usual and final plant is were small. With judicious watering I got them through to harvest but the yield was less than expected.
I still use Ocean Forest and/or Big Rootz as my growing medium, only I add perlite in at about 1 part perlite to 3-4 parts soil. This gives me improved drainage, and I haven't had the top dry with a heavy, moist bottom again.

I'm no transplant expert but they look like they have recovered well from the transplant but are probably putting down roots filling their new pots.

You VPD looks high, maybe try raising RH 10% and wait for them to fully establish before flipping.

Do you have runoff when you water? How well do your plants drain? Does the one that looks the best drain better than the others? The leaves appearance make me think overwatering. It's very easy to do, at least for me. I've learned that less is more.

Thanks for the feedback. I haven’t watered until runoff. I wasn’t sure if watering that much would be too much. I’ll let them dry a little longer before watering again.
