I’m running multiple 1000w Bestva and have the lights now at 32” because of slightly burnt tips. Have the tips burnt because the light intensity is too much?

There's various reasons as to why your plant tips may have burned this early . One of the reasons is that you are using nutrients they might be strong still , i would dilute it even more if I were you 1/4 strength . The other things could be potential light burn 1000w output is a lot of your young seedlings , I would find a way to reduce it to 400 watt at the very most for about a week or 2 then kick it back into 1000w . Theres a few reasons for this a) the plant can only absorb so much photon's so even tho your running 1000watts of light the plant isn't able to use 1000w worth of light b) the light is very intense for a young seedling so you could cause light burns if your not careful . So if your able too dim your lights down to 400w or a little below that and bring it up over time . Reduce the amount of nutrients fed as they are very very young and adjust the doses accordingly. Remember that less is more when they are first starting off .

Hello @SCgrow ! I don't really see any light burn ( although 1000 watt is to much ) or any major nutrient burn. Just lower a little bit the dose of the nutrients and you will be fine! Also you need to buy an EC meter if you want to keep going with those synthetic fertilizers otherwise its very possible you are going to have problems with the nutrients again at the future. Happy growing ! 👊

You wanna have those lights just high enough man, depends on penetration really, if you can lower them to around 20 inches. Make sure the lights are all "straight" because if they're a bit too crooked next to eachother can cause some extra lights in a bad way. that burnt tip though is nutrient burn, probably because your soil was "hot" - just keep following the wet dry cycle, maybe dial back anything with N in it for a while, dassit ! 🚀

Hi SCgrow, Its not your Lights that burnt your Babies. That looks different. Bunt Tips are a true Sign of Natrium Excess. The Tips get yellow/ brown and die. This damage is happened days ago, it takes time until they show that picture of excess. In my opinion wait with nutrients until the End of week 3 , you soil has enough food for the babes. If you start Feeding take 1/3-1/2 of the recommend amount of Fertiliser and look how she reacts, then you can raise the amount slowly The Lights ale also for Plants that are older than 3-4 weeks ( after root development) try to reduce the light ( dimming) For further questions darke to ask per PM

Most likely it's because you are feeding too early; let the plants feed from the soil, only give them nutes if you see a deficiency. The lights been too close can give them heat stress, where the leaves edges curl up like a taco
