    Rockwool Pros???? Deficiency week 2 of flower??

    Well im pretty positive it's just fungus gnats but I'll take a closer look. Just hit everything with nematodes to shut down the issue... And I'm pretty positive at this point it was all caused by being rootbound/ not enough volume... i potted several plants in plastic post with gro cubes and...

    Rockwool Pros???? Deficiency week 2 of flower??

    and I'm getting plenty of runoff... irrigating based on the shot size... the recommend 3-6% shot size (of block volume) ive been all over the board.... too much, too little... now im around a 5% shot size in flower feeding every hr (but ive tried way more feedings even up to every 20 min) same...

    Rockwool Pros???? Deficiency week 2 of flower??

    temps are like 75* rh is at 50% i think it is a root bound thing... ive tried lower ec, tried higher ec... i noticed yesterday several of the cubes had irrigation solution running off them... its like the top of the 6x6x6 are a solid mass of roots... i have to get the drip stake and punch it...

    Rockwool Pros???? Deficiency week 2 of flower??

    I'm leaning towards these being root bound and trying a few plants in 5 gallon pots of gro-cubes fingers crossed this will help anyone chime in, yay or nay?

    Rockwool Pros???? Deficiency week 2 of flower??

    this is all drain to waste, so the nutrients are fresh pulled from the dosatron every irrigation cycle... my nutrients are two part. part 1 is CalNit (calcium nitrate) part 2 is either HVG Growth or HGV Flower...

    Rockwool Pros???? Deficiency week 2 of flower??

    I need HELP, wtf is going on??!!

    The ONLY differences are I'm using DE lights WITH Co2 and MUCH larger plants (because of plant count limits) with dosatron system and I put plants on unislab first day of flower I used to feed 100ppm calmag (.2EC) and total with A & B was 600ppm (1.2EC) @ 5.8 ph so on advice from grodan I...

    I need HELP, wtf is going on??!!

    I'll have more pictures of everything Monday through the hps sunglasses so you can see colors and get a better picture of what's going on.... buds look dank AF though and huge for only day 35 but obv things could be better if leaves/ plants aren't perfect

    I need HELP, wtf is going on??!!

    Hey guys, I've been growing rockwool dtw for a couple years (growing over 6+ years overall) It's great and I've always done very well, my home setup always looked perfect. I fed 0ppm ro water with 100ppm calmag (.2ec) and 600 total ppm after a/b (1.2ec) I feed this throughout... plants always...

    Ok guys soon without doubt it was the lights... Too much light over 18hrs... Even at 650w (22 gavitas in the room) Once I dialed it back to 12 hrs they INSTANTLY bounced back. Now they're all looking great!! Still some dialing in to do and not on my phone with pictures now but I'll post some...

    I think I have the solution.... talked to a commercial grower I believe knows his shit, he said the 18hrs of intense light from the gavitas was just too much for the plants. It makes sense and i thought it was a big difference but had never experienced it... I've seen the jungle boys veg room...

    And I just noticed you said 6.3 to 6.5 made your problem go away! That's surprising, i'm assuming you're in soil where I'd think 6.3 would be just fine. Since im in rockwool I've always been 5.8 on veg and bloom, plants always looked immaculate on my old setup with those ph's... been growing...

    Yup... so on the 500 scale I'm pretty sure its about 170ppm of calmag they're getting. I'll run a test on the dosatron tomorrow to make sure that's what it's coming out at. And I agree it looks like ph is outta whack which would cause all sorts of lockout issues explaining my symptoms but the...

    Thanks for the tip, it seems reasonable but with the dosatron system it says my ph is between 5.6 and 6.1... I've checked several times and it seems the ph is on point. I'll look into it a bit deeper I do know my well water is low ph so after RO the water comes out at 11ppm It takes quite a...
