I'm not a hydro guy but that looks like a salt build-up in your plants to me. I also have no clue as to what high ph does to plants in hydro so for all I know I'm blowing smoke out my arse. Are you using chemical fertilizer on your babies? Ok, that's it I'm out of guesses.
Just finished fingering my girls for a smell test, nothing like a sweet smelling vagina...after all, aren't they nothing but one big vagina while flowering?
Here's a shout-out to whomever, (you guys were talking about old folks, so please excuse this one for being an old stoner and not being able to remember what came from where) the c4/caseyband ended week five of 12/12 yesterday, sweet, sweet, sweet and very frosty. This baby is going to yield some super buds. Also, the romulan. I have not smelled a plant that smells so purely sweet as the romulan. She went into 12/12 on the fifth of march along with a green poison. Smallish buds so far but very frosty and the nicest sweet smelling plant I've grown, it has a fantastic aroma. The green posions are also very sweet smelling but not like the romulan and unlike the romulan they produce a nice looking plant with nice hard nugs and I expect her to finish in eight weeks from seed. The company says seven but it ain't happenin'.
So thanks to somebodys for sharing.
Another thing, I switched to all organic last grow and have continued the practice this grow. Is it my imagination? My plants seem to produce a much more oily resin now than sticky. The c4/ caseyband is both oily and sticky but all of my other girls are much more oily and I also noticed this my last grow too. Any opinions?
And we all grow in our own ways and harvest when it suits us, let's not get into a dick swinging contest eh boys. Not trying to be an asshole just sayin'. We have great vibes on this thread, we are all welcome to disagree, let's keep it civil, shall we?
