First grow

The yellowing appears to be due to hot soil, nutrient burn from excessive chemical nutes. I personally would just move forward with plain water (reverse osmosis if available) until the plant begins to ask for nutrients. Young plants seldom need supplements when in any kind of potting mix which can typically feed an average plant for about 1 month per gallon of mix, heavy feeders on the other hand will likely require supplemental feeding later in their life, then start with 1/4 dose and move up if required.

Well u do have tiny amount of nute burn but other than that the tell lanky plants just need to be repoted

i can only agree about lanky ones, they need more light ! BUT they need air movement too, to make theirs stems stronger, so from garden wire you can make support like i did here growdiaries.com/diaries/135979-grow-journal-by-asnoriu/week/737550 older ones, looked like clones to me too ;) anyway, they heavily overfed, i would consider to transfer them to final pots asap and not feed for few weeks even. All weed specialized soil has plenty of goodies for few weeks anyways. All the Best !

same as last time, your soil too rich or you just bombard them with nutritions and bad ph

study one spot on your plants and look to see if you can see any almost microscopic crawlers (aphids) on your plant. Also check the underside of the leaves for white spots..check the soil for root aphids. fungus gnats dont mess up your leaves like that. must be that or you are not waiting for the soil to get dry before watering. Overwatering will kill a plant and its the mistake i made on my first because i had OCD about it. Just be patient and the plant will tell you what it needs. In the plant world , more isnt necessarily better all the time. But ya pests, or watering practice. That or transplant shock.

Hi there They look abit over fed.. give them just water the next two feeds then cuts the neuts down a tad .. maybe add a small amount of calmag to sort out the calcium side of things Best of luck 🌱
