The 1st thing you have to do is correct your PH value because in coco the sweet spot is 5.8 and you can go up to 6 but you are at 6.5 since week 2. Cannabis is not very tolerant to ph issues in coco ( check the ph runoff ) The 2nd thing you need to do is to get a ppm/Ec pen to know the exact nutrient amount you are using for your feeding ( input ) and the runoff ( output) because it will also tell you if there is too much or not enough nutrient in the coco. If you are able to check and control these 2 values you can makes them bounce back if you don't forget to add cal mag with every feeding.

Looks like a case over feeding and over watering my friend. I highly suggest just giving her balanced water, in smaller doses, for quite awhile. There's a good chance she'll bounce back. I know you're following the schedule, but that schedule is assuming your girl was a little bigger by this time. She had a couple set backs and is not ready for the heavy nutrient feeds they recommend. I would also check and make sure the schedule you're using is the correct one. If you're using a coco nutrient feed schedule, these are usually higher doses than soil media. I just recommend backing off the nutrients for awhile. The symptoms are not a lack of nutrients, but an abundance. Feed with balanced distilled and/or low ppm tap and localize your waterings as best you can and never too much. Saturated soil with no root system can suffocate, stunt and starve the girls. I wish you luck in the coming days👍👍

Hi. These plantslook like they have been overwatered. Letting your soil dry is as important as watering it. They were fine in the little pots there was no need for transplant. In big pots like this its more difficilt to give the right amount of water. The humidity dome didnt help either. Make sure you dont water the whole pot, just half a cup of water around the seedling when necessary. Then mKe sure the soil is dry before watering again. You just transplanted theres no need to add nutes yet. Your soil should have nutes for at least 1-2 weeks. The reason they look like they lack nutrients is because of the overwatering, the roots are rotting and the plants are unable to take the nutrients that are in your soil. Read online about the wet-dry cycle and you shoyld be fine 👍 Good luck!

Hello Friend. For me it is better to put them in another biobizz soil and put a little water with root juice and calmag per milliliter of 1 liter of water. HAPPY GROW 👊
