I don't think there's nitrogen toxicity at all! I agree they look quite "stretchy" moving the light closer will help prevent this. 🌱👍

Hi BBFower Looks good mate you probably have very slight Nutrition toxicity. Not to worry to much at the moment. I am thinking more you could get your lights closer to stop that stretch on internodes buddy. And I will lower PH to 6PH. It works great with Soil. For the Nitrogen deficiency Suggestion- Solution: Reduce the Nitrogen your plant is getting! Reduce the amount of nitrogen that is being fed to the plants. If you are feeding extra nutrients, cut down that amount. If you are in the flowering / budding stage, make sure you’re using a formula that’s specifically meant for flowering, or else it could have too much nitrogen. If you are not feeding extra nutrients, you may have “hot” soil that has been giving your plants extra nutrients. In that case, flush your plants with filtered, 6 PH’ed water to help clear out the extra nitrogen. Effected leaves likely won’t recover, but you should see the problem halt with no new leaves being affected. Marijuana plants that get too much Nitrogen in the vegetative stage don’t grow as vigorously. Too much nitrogen is especially harmful in the flowering stage, because this will cause your plant to produce much smaller buds. If you react quickly and reduce your nitrogen levels at the first sign of toxicity, your plant will quickly recover. And I will lower PH to 6PH overall. Hopefully this helps and good luck with your grow.

stats are good.runoff ph 6.6 is good,soil is clean but they look lanky.I think because of 12/12 from start.yes it looks like a N toxicity at first but you should watch if it spreads to upper leaves.since both have it on first set of leaves,it would be a genetical situation.upper parts don't have any signs and overall it is a nice green.I don't think it is a N toxicity.But I would still cut off Nitrogen to stop internodal distance getting any bigger,just start giving bloom nutes at this point.Flush not needed by the way.Simply no need.
