Hi Everyone, first time grower , this is a dwc details: my ph is 5.8-6.0 humidity is 45% week 2 seedling using GH flora grow ppm is 750 (tap water is 160ppm, included in the ppm total) res temp is 19c res 36gal lights 12" from top of res (T5 HO) 18/6 cycle room temp is 23c Can anyone tell me whats happening to this girl im at a loss of what to do? thanks in advance!
looks like a cal and or mag def to me not to familiar with dwc so not sure if it could possibly be something else going on with root situation im sure a hydro guy will chime in
Salted up, rinse roots with fresh water and add fresh nutes and water to res at 300-350ppm, let pH swing up to 6.2 before you re balance keeping it low all the time can lock out some nutes as well.
Hey Fullmeltalchemist, thanks for your advice, do i pull the netpot out and run the entire thing through fresh water? or just rinse roots? Also i'm using tap, i have some distilled, should I rinse with tap or distilled? thanks!
I run tap water with no issues, never tried using distilled but then you need more additives like Cal-Mag. If you cant rinse the roots with a flexible shower head than fill a 5g pail with water, submerge the roots and massage them clean with your fingers but be careful not to tear any.
You are massively overdosing it. Add water until the ppm drops to about 300. It also looks like you have wet the leaves in the past
thanks everyone, great advice. btw i realized my ph meter needed calibration, so possibly why i was having more issues (guess i have to calibrate more frequently). Anyway I've dropped the nutes to 300ppm and upped the ph to 6.2-6.3. The leaves have become less droopy, they seem happier!. once they seem stabilized what should my ph be at? What do i do with the damaged leaves,, do I cut them off or just leave them. if cut them, where do i cut them at? how do I know what height to run my lights at, i have 8x t5ho 54w .
Ph problems are very rare, so even if the calibration is out, it's unlikely to cause you problems. Anything between 5.0 & 7.0 is fine, but between 5.5 & 6.5 is what you should be aiming for. Don't cut anything off, that will just provide the plant with more stress. Let it heal and become healthy again before doing anything to it as far as training or cutting bits off. Try and keep the bulb within 4" of the top of the plant if the temperature allows
