Hi there! I'm kind of new to the forum thing this is the first one I've ever joined but I've spent hours reading stuff on this forum, I just never joined until recently to hopefully get some help and save my plants. I've looked for hours without being able to properly diagnose whats wrong with my plants. Got two sick plants, a tangerine dream and a white widow both around 5 weeks into flowering that are dying quick! At fist the leaving starting to turn a pale whiteish yellow color that kind of looked like it may have been light bleaching starting at the top and some starting twisting and getting curly and then crunchy and it looked more like a nute burn, this was the day after i changed the nute solution. I used full strength nutrients as directed on the bottle before this since the plants seemed strong and were drinking quite a bit so i thought they could handle it. Prior to this I used a slightly decreased dosage, I used what the bottle said for 4 gallons in a 5 gallons bucket the plants whole life and it was fine until now. After this I emptied and refilled the bucket with the regular dosage and waited, and the next day when I get up the plants were way worse! All the leaves were hanging down and the the pistils are shrinking and some are turn brown faster. After noticing this problem i changed out my solution again and used only half strength and it has been a day since then and the plants just continue to die. I might have lowered the ph too much the second time I changed the solution so I made sure it was around 6.0 this time but the plants show no signs of getting better. The plants look like my first grow I did in soil when I didn't water them but I don't understand since its a dwc system. The air-stones are putting out just fine so i"m stumped on this one. This is my 3rd grow and I haven't run into anything like this before. Please help I don't wanna lose them! Thank you in advance for your time, here's some more info:

600w hps
Using Jungle juice nutrients, and I usually put a little peroxide in the water and have to lower the ph with ph down
Dwc 5 gallon bucket with tetra whisper pumps for each bucket, says up to 40 gallon aquariums on the box
Roots look like it might have root rot but I'm not sure since the nutes I use have color to them, still smell ok but seem a little mushy maybe

I will put some pics in the next post If I can figure out how, thanks again in advance!

either root rot or salt build up from using full nutes. in dwc the plants need much less nutes because roots are in constant contact. i never go above 600 in dwc.

Excuse the daft question SS (I've never done dwc).
In general, would you say dwc uses less nutes (for the same plant growth?) Or do you get through more water?
I mean in comparison to flood/drain.
It's just I'm looking for a cheaper way to do my outside (legal chili) plants in summer and nutes is a large part of the cost. Also, how is root growth compared to F&D? As you probably know, bonsai is a big hobby and I am interested in kepping the roots as small as possible.

Thank you for your reply!! I thought that could be it, I was thinking possibly a combination of both. Do you have any suggestions as to what I should do? I read that just putting nothing but ph balanced water in the bucket could help the problem, do you recommend this? And as for the root rot I read that removing some of the roots may help, would anyone recommend this after looking at the pictures? I reallllly need to get a ppm/tds meter!! Thanks again for replying!!

In my experience from the looks of the tops i would have said root rot, but you roots don't look too bad, certainly not enough to cause that kind of damage.

thanks for your reply! Thinking a possible ph problem and or nute burn with a small side of root rot? They are not looking good at all :(

If anyone else has anything else to suggest please do! I'm very worried that they're not going to make it. Thanks again to everyone who has responded :)

never done e&b. by far dwc is most efficient on nute use. use almost double in aero.

its important to have the proper tools with hydro, and its ok to start with cheap ones. its hard to say on the roots but they do look a little mushy, i would flush with tap water, there is no need to ph flush water or cloner water, ph affects nute uptake through the roots and with only water there is no need. if you have acces to a hydro store get clearex or another flush agent to help break up the salt. i would also recommend a beneficial bacteria, like greatwhite or podzyme. keep temps below 70 in the res.
