New to soil - Curled down tips

[alissha16]

Ok we have 7 plants veggie. We reported them just over 2 weeks ago and the problem began about a week ago. The new and newer leaf tips are curling under. On the sativa, a couple of the newer leaves are starting to canoe. We have been watering them with Phd tap water about every 3-4 days. They have air stones under each except the sativa. She's in her own pot with drainage holes. Her roots look beautiful.. The planets otherwise look beautiful and are growing perfectly. We used nutes once (advanced) when we transplanted. We have 1000watt light on 16/8 off ... I believe... I keep reading different reasons the plants could be doing this and it's a little frustrating. Any help would be super appreciated! Thanks in advance.

Are your plants on the concrete floor with no insulation? If so, I bet they will do better with a little foam padding between the floor and the pot. Cold soil can create nutrient availability issues. The plant leaves are dark so that could signify nitrogen issues (aka the claw) but it doesn't look to crazy to me. I would do the foam thing or raise the plants up off the floor some other way.

Your nutrient mix was to hot mate and your plant is showing classic N overdose with the clawed leaves, just feed with water or 1/3 of what you gave before and they'll, correct themselves soon enough

What he said. You got some pretty classic yellowing along the veins also from Magnesium issues, but resolve the overdosing first.
