the ppm should never exceed the wattage of your light and thats at the very end. if you veg 4 weeks (veg not seedling.) and flower 8 weeks. from the start of veg i would use 50 ppm or less of nutrients and increase by 50 per week till week 4, then no nutrients period. (cube, solo cup, 1 gallon, 3 gallon).

@Johnyb,ok I see now. I wasn't sure between over watering, over feeding, and too much light. Now I can definitely say there's maybe too much light bro, this is why she's droopy with purple stems and tips and stripes taco'ed leaves. She's out of Mag and can't photosynthesize properly. That 300w led at 15 inches might be a lil bit too close.

your light, especially an led, should be at the top of the tent. the light needs to spread out. your plant is about a 35 watt plant. if you give it 300 watts its going to run away fast. the plant cannot go faster than 100%. the nutrient bottles are way, way, way to high. the nutrient bottles make an assumption that you probably don't know about. their bottle assumes you have 10 plants in vegged under 600 watts in 1 gallon buckets, flowered under a 1000 watt light in 5 gallon bucket. and those measurments are not to be fed weekly. the max ppm you should ever be at is the wattage of your light. 400 watt light 400 ppm, and thats for the week total

Good Morning, Glad to have a new grower on the map. Might i give you some friendly advice. I would back the light away a lot. the leaves are bending down like a slide (possible to much light), saw toothed edges on the leaves (pointing up and looks like a saw blade, not enough mag caused by to much light), leaves are taco-ing, (pulling the outside of the leaves up and moving them in (not enough mag). the brown tips on the ends of the leaf are from too many nutrients (usually, highly likely). I hope this helps you succeed with your grow better. :blush:
