Hi guys new to the hobbie and was after some help identifyide an issue im having. Looks like nute burn but not using nutes. Using a t5 slim line tube lights so no heat coming off them (done the hand test) Its like a white spot getting bigger on all leafs Plants are about 5 days old
It looks like the soil is saturated. Did you just water? I’m not sure it’s mold but that’s what it looks like to me. That’s pretty humid but vegging plants like humidity. Maybe someone else can verify it.
I start my seedlings under a single T5. Six inches above until true leaves, then drop the light to three and a half inches. Once established, I run eight T5s at three and a half inches above canopy. Are you burning your seedlings?
Its coco with perlite. Yeah i use water at a ph of 6.1. Yeah i read somewhere to have it at 80% then lower it to 60/70% is 80% too high then?
Lights about 4/5" above the plants it was about 6" or 7" above when that white started lowered light as plants where stretching. Recommend raising the lights?
Well, it sure as hell ain’t light burn. 2x2’... I require 8x4’ to grow two plants. Check with @Papa Puff He knows his ‘white stuff’.
Did you pre-charge and rinse your coco? That could be your problem. What is the ppm and pH coming out? I don't think it's the light - I use a t5 and put it within inches without problems. May I suggest you learn how to properly grow in coco? Here's a good place - www.cocoforcannabis.com. Good luck.
Yeah rinsed it 3 times unril the PH run off was 6.5 its now at about 6.1 and precharged it with root stuff and shogun start. Not sure about ppm as still waiting for my meter to turn up gotta love ebay...lol. sweet cheers il check it out
