It's been 15 years since my last grow -- it's already been a really humbling experience. So much is similar, but a lot of the tech has evolved. But my nutrient knowledge is rebuilding. Anyways, was hoping to post here in a couple weeks outlining my grow, the build, etc., but had created this account knowing it was likely I was going to need it.
These are pics of 3 sprouts going into what I'd consider the 6th day of their first real week of veg. I began germination 3-30. I moved them into a small, temporary DWC system under an HLG 550 (the blue spec one) initially at about 20% power, dialing it up each day a bit but have stopped it at about 40% power -- 32" from the tops. They're in rockwool cubes sat in hydroton. No drip lines here -- What I do is keep the water level up bubbling beneath the rockwool and drop it with an adjustable float valve as the roots develop (there's RO water coming in to that valve). First roots are showing through the hydroton.
Water temps have been stable at around 64-65, Ph stable at around 6.0-6.1, room temp lower than I'd like at about 65 F and humidity low as well at about 45%. I'm using the Fox Farm Hydroponic feeding schedule and shooting for a 1/4 to 1/3 of the recommended strength. There's a small amount of superthrive in there -- about a 1/2 mL. They initially received the amount under seedlings and then when I swapped out the res I upped them into Week 1, shooting for a 1/3 strength. So, the water is at about 325-350 PPM. That doesn't seem unreasonable to me, but this looks like what I remember nutrient burn looking like. This would have been 4-10 when I upped the nutes a bit and initially two of the three started to shoot up -- the smallest I noticed nute burn on first, 4-13. Yesterday I noticed what looked like it might be the beginning on the two taller ladies. But it's progressed a bit.
Unfortunately, all I have in that room is that blue spec HLG 550, so these pictures were taken under that. I'll get a work light in there as I build the room. I'm building the permanent set up as these ladies grow -- talk about working against a clock. Never have I had as much motivation to complete a house project.
I've reviewed some pictures here and the stickies in this thread, so that's kind of confirmed that suspicion. I'm a teacher, always requiring my students to have reviewed the material, and having done that now I believe that what I should do here is possibly swap out the res, flush the medium and bring the nutes back down to a quarter strength for another week, given how young they are. But my first rule as a grower has always been.... DO NOTHING. So I've been doing that but this appears to be progressing
.
I'd like to not kill these ladies if possible and so I come here, hat in hand, asking for help, assuring you I'll pass it along! <3 Thanks in advance for your time and help.
