Brother you need a little cal mag in your life lol, it contains a little nitrogen which will help to darken up the leaves plus obviously keep the calcium and magnesium issues especially in coco. EC is quite high they must be a strain which maybe requires higher than average levels.
To be honest though they look real good๐
@bobtheblob, canna actually now sell a cal mag additive so might be worth buying theres.
Many company stripped the cal mag out of their 2 part feeds over the last few years to force us to buy a separate bottle lol
@Esoteric_growing, yep, I reuse it all the time and probably not flushing it properly, that shrivelling looks like chem burn to me. Not all seedlings suffer from this though, so it's a combo of bad coco + sensitive gal I guess
Amazing grow! Really good job dude! I wish you the best results with the most delicious buds!
Nice to see your journals! I will drop by some times to check your progress!
