Thankfully the heat under the lights is nothing at all. led is cold that way and all the heat is the power pack running them , hence the fans to pull it out of the lights box.Just water and pH down for now, I have an EC/TDs/ppm reader but I can't figure out what batteries or where they go in it. IV emailed the eBay company but no reply so I'm just going without ATM. That new sprouting has yellow on its leaves and just yesterday the Coco was moist but today it was dry so with the new light in there I'll check it every day to ensure it's good. The girls are loving the light they have really opened up and are reaching for the light. I'm not sure how I'll tell the node count with them being so small but I can already see the two round leaves + two weed leafs and another one just starting in the middle of each.
On a side note this new light raised the temp in the room by a few degrees and 3 degrees in the tent alone so IV rerouted the exhaust fan out of the room hoping that will help with ventilation. I don't want to start a fire whilst I'm out of the house due to heat but my thermometer reads 29 under the light but that's about 30cms down on the ground, the plants would be under more heat than that I assume. Problem with the light is it's so damn heavy it's hard to tie it up, I'll have to look at some steel chains or adjustable chains for it.
Nodes is another term for " paired leaflets, so each pair of leaves up the stem are " nodes" .When you have about 3 or 4 proper leafsets , then mild feeding can benefit them. The yellowing could be light related if they are too close at this very early stage of their lives. The viper site should have a guide for their light hanging heights for each stage. It is surprising how powerful and intense an led can get for new plants and can bleach them out . keeping the coco moist ( not soggy) is the key here atm. she only takes water for a while and as no nutes yet , oh isnt too important. On nutes , the ph of the water is only to allow the Salt to release whichever trace elements in is attached to it when we feed the rootzone. At the right ph ,5.8 for coco , then you can hit the majority of elements that use that acidity/alkalinity to seperate from the nutes salt ( used purely to transport and hold the elements together till the water hits the root zone where the ph dissolves the salt part. This is why we flush the medium with an occasional rinse of just ph,ed water during their feeding cycles and why the runoff to 10-20% too. With my Mega crop there is no need to do it either as it isnt .adele like normal salt based nutes so no separation is needed so no ph. you will pick all of this up along the way and dont worry about asking anything. There are a lot of subjects regarding growing and a ton of opinions and ways for each so we are all still learners here too. My 1st ever auto grow now , 1st time using soil to grow for so e too but I have been growing weed over 25 odd years. I learn stuff every grow still now and new methods and stuff are coming thick and fast at present so we learn together as a community. merry xmas mate
