Hi all, My LR2 sprouted this morning. Its my 1st grow and was really excited but at closer inspection i noticed 1 of the leaves is yellow??? I'm using a 250w CFL in a wardrobe with mylar on the walls. Planted 2 days ago into a 10l pot filled with Biobizz Allmix. The light is about 3/4 inches from the top of the sprout. Help please!!!!!!! Thanks
I dont know much about the soil you are using but from all the white stuff it looks like it might be pre-ferted soil which is just totally going to screw up the plant. So it looks like you might have nute burn already. If not, the 3/4 inch from the light also sounds a bit close to the lights but that should affect your first set of leaves first and not the cotyledons, as is the case here. You really want to be 3-4 inches from the lights. I would repot into non pre-ferted soil at this stage b/c doing a flush with such a small seedling would probably kill the seedling ... but maybe not.
Sorry i meant 3-4 inches... So from what i've read i dont think i could have burned the plant from that distance using CFLs. Maybe it is the soil, It does have some fert in it - 2l fert in a 20l bag of mix. although i bought it from my local grow shop...
Yeah I really want you to trust me on this 'cause I just went through the same thing. It's the pre-ferted soil. Please repot it to diiferent soil or if you cant't (like I couldn't b/c all I can get is pre-ferted soil) then flush it well. That yellowing at this early stage is a clear sign of either the wrong pH or nute burn.
the soil is burning it. get it out of there today if possible. things will only go downhill until you do. Get a good soil without time release nutes.
