Slow growth, advice appreciated. Pics & description

Struggling with slow growth. The largest plant is over a month old with most of the others at about 3 weeks. I started in Solo cups with Straight Happy Frog. Struggled with temperatures for the first week or two I am sure that isn't helping. Transplanted at a week and a half at 3rd nodes to the pots they're currently in. Does soil mixes 40 Happy Frog 40 Coco and 20 perilite. I am using old age organic nutrients at 3/4 strength. Water is pH correct. I do think I have been over watering with pots too large. Not sure that's all of my problems though. Growth has seemed to be stunted since the beginning. I just can't figure out what I'm doing wrong and any advice is much appreciated thanks guys

First off your fan is too high it's blowing on the light and not on the plant tops, you spilled water on the one plant LOL, try and learn how to feel the weight of the pot for when to water, they have to dry out completely between feedings/watering. Other than that you look okay, slow growth or not, looking green and healthy. What light is that above them and can you lower it a bit by chance with out the back of your hand burning? Let me know thanks.

Thanks for the quick response imagine impatience is going to be my number one enemy this grow. I have moved the fan lower the light is a 600 watt metal halide it is about 17 inches away from the Canopy top and temps are about 80 degrees with the lights on.

They look good. What are you growing.?Some strains are just slow. I had a couple train wrecks that were slower then slow.they pist me off really. Oh and they were nutes sensitive.. But thoughs look nice and healthy. Just don't get to impatient and start blasting them with nutes hoping to encourage faster growth.. They may take off as soon as they get to flowering good. I would keep doing what your doing and be patient

Thanks for the response farmer, staying out of the tent for a few days... haha

I think topping and transplanting too soon without recovery on young or picky plants could possibly cause enough stress to slow it down, Overwater it during the same time and youll have even slower growth.

Also,i dont think you should be using synthetic buffers with old age organics.

OK I will keep both of those things in mind in the future. Those sound like the most likely. Not 100% about the brown tips on the biggest plant though.

I liked the idea of getting the best of both worlds but I'm quickly realizing that's not how it works. I will skip that step also. Thanks for the reply
