HELP!! First time hydro in need of help

Can someone please tell me why my babies are so unhappy right now? Aurora xMaster Kush . got them about 5 says ago in rockwool.Deep water culture system. 210ppm using massive nutrient line. Ph is 5.5. Water temp is at 76, room temp is 78 on a 24/0 under a 400w MH super blue. Could this be nutrient lock out? Or could this be from undeveloped roots?

Yes your right its nute lockout because your ph is wrong. Make sure the ph is 5.8 or things will get worse. 210 ppm seems a little low.

What's a good range to keep it between?

When I was at this stage, I had a ppm of 250 so 210 is perfect I say...but I didn't use any grow nutes at this time... only CALMG+

Looks to me like drowning plants. are you using a bubbler or just that drip line? and 5.8 is ok for DWC though 5.5 is usually what I shoot for, but 210 ppm? if they are already rooted thats a bit low, imo you need to add a big time bubbler to your res and use more nitrogen,

I usually dont see stuff like that in my clones so I cant really comment on the underdeveloped roots, however IMO you will see better results if you ditch that drip line and raise the res water to just touching the roots and throw in a bubbler

Hi there, they look big time over watered brother. That is rather common when they do not have a good root system developed yet. 5.5Ph is a tad low, but that by itself will not make them look like that, at least not in my experience. Make sure your meter reads correct, you can use the PH drops for that, aim for piss yellow The drops are only $6 or so. Watering interval should be like 30sec. every 2-3hours until they pull out of this (lights on). Cycle timer works great for that.

Good luck,
Kind

Depending on the PPM you water is starting at 210 seems to be a little high for the size of those (already stressed) plants, you pH should be at 5.8 - 6.1 at this stage and your water temperature are also a little high; you should be looking for your reservoir temperature to be around 70°C - 75°C.

Do you have pictures of the root, I would imagine if you think they are underdeveloped they probably are?

Looking again it seems your pH could be locking out Mg, Zn, and Fe. Get your pH tuned in and then see the results.

Here is a picture of plant with the locked out nutrients I described below, the leaf in your last post looks very similar.



regards,

Alright I shifted the Ph back up to about a 5.9. The res is now at 74. The roots are barely visible right now. Im going to raise the res level to root level. But let's say I want to just use the drip system. How often do I turn them on and for how long?

How long will it take for the plants to respond?

Alright the plants stopped getting worse so hopefully in the next couple of days they will start greening up. Very much appreciate the advice. Thank you.
Keep it sticky.

My guess is the roots will not be ready for the DWC soaking. Any pics of the roots?
