DWC Plants seem to be becoming sick

[Blizzin]

Don't raise the lights......you're using flouros right? Just grab a good paper towel and go around pulling leaves apart and dabbing up the moisture. When you see two leaves overlap that is usually where water forms. If you raise your flouros too high they will become useless to you. I honestly believe your issue was water or nutes splashed onto the leaves and ANY light will burn wet leaves. Dry yours.

IF you are running straight DWC I'm not surprised that the lower leaves are dying off. As long as your new growth looks good and it's just the older LOWER stuff I personally consider that normal. If the drooping starts crawling up your plant and appearing in the newer, higher growth I would call it a different issue.

As for humidity.....all you can do is your best but if it remains high you may very likely encounter disease issues later. Consider a good fungicide like Serenade and follow the directions on the bottle EXACTLY......anything you can do to prevent your molds and funguses is good.

Your welcome. Hope that info helps.

well just flushed everything out and used half nuts now 630ppm for 5 gallons and recalibrated blue lab tester was .2 off, so see how it works. Also thinking off splitting plants into 5 gal buckets is it worth it in your opinion Weed and this late in vegging? almost 4 weeks anyways thanks for help

Blizzin, you write that you're using GH but that is a three-part nute. Are you using the Micro part as well? You probably should be using all three, the veg, micro, and flower ferts together in different strength depending on the cycle. For example, use a little more of the veg fert (green one) for veg growth and less of the flower fert. Use the same concentration of micro throughout the entire grow. It's good that you measure both pH and PPM. This is necessary in hydro, but no so necessary in soil. It looks to me like the spotting you're seeing is probably magnesium deficiency, but it's hard to tell for sure because the spots don't show too well in the photos. If what you're seeing is golden-yellow spotting in between the leaf veins (on the meaty part of the leaf), then it's probably mg deficiency. It isn't enough to just use one bottle of GH nute. The reason why nutes for hydro are seperated into different containers is because the manufacturers want to give the grower the ability to modify how the ferts are used and tailor them to different situations. The other reason is becuause the manufacturers want to get more of your money. But since you're using GH you can get the micro if you don't have it or just throw in a small amount of epsom salts, like half a teaspoon and see if that makes a difference. If I'm right about it being mg def, then you'll see the plants improve in about a day or so. The bummer about epsom salts is you need very little of it but have to get it in a large container typically, at the drug store. I've seen mg def before and that's pretty much what this looks like. The GH micro has magnesium in it, but the micro is the only bottle. One other reason to split the ferts out is to prevent the elements from binding to each other and falling to the bottom of the container. Then they're useless. I'd leave the PPM at 1200 as I think that's a good number for DWC. In fact you might consider raising that to 1400 as the plant looks rather large. It looks fairly good so far, I think you did a good job and you're almost there. If you feel you can clone that thing, go for it. The more, the merrier. I don't know how cutting PPM in half will help as the plant looks good now. You just need to identify the problem and fix it. There's probably pics on this site and on the web of deficiencies. Try googling if you want, but I'm pretty sure it's mg def based on the pics.

When you switch to 12/12, just cut back a little on the veg fert and give more of the flower fert. Keep the micro amount the same. You just shoot for the same PPM number, only higher phosphorus, lower nitrogen. By the way, it's almost impossible to light burn plants with flouro, even if the leaves are wet. Flouro just isn't hot enough.

Thanks for post. Yea i use all three of the GH nutes. Micr,bloom,and whatever the other one is and following bottle instructions for veg phase. Damn I am torn between 2 opinions cut back nutes and add slightly more hummmm.. gonna let it go another day or 2 and see how it looks.

[polishpollack]

Yeah I figured you'd feel stuck. I don't think 600 PPM is enough. What about the spotting? Are you seeing golden yellow spots in between the veins?

[Weedhound]

Thats one of the reasons I suggested using RO and CalMag vs bottled water. But I am not seeing an mg def there and I dont think you need to go higher. If you do.....watch carefully for overnute.

I'd still love a photo of the entire thing.....it would help a lot.

[Weedhound]

And I completely disagree that flouros can't get hot enough to burn wet leaves.

hey wuz crakin this should be a easy descision on who you should listen too,
heres what you do look at the join date of member/then look at their reputation/then look and see if they have any grow logs in your type of growing water or soil then apply a little common sense and go over the post again.

too me, the pollock is steering you in the wrong direction and is a inexperianced grower and poster as you can see in his reply the first thing he asks if you have the GH micro nutes which you clearly stated you have all 3grow/micro/flower
but he misses that in your post and tells you too go buy it, things like this are big indicators the person replying is inexperianced ! and you should take their recomendations with bigass of grain of salt


hey WH, I actually burnt my finger on my T5's the other day not bad but it bubbled doh! mine are a tad hotter than commercial as they are a cool ass DiY fixture

so if your still unsure you should ask more questions, i'll leave you in very competent hands the weedhound's hands good luck

Ok new pics Tuff to get pics of single plant sorry weed hope this helps and thanks again

i dunno, i think they look great. but are you going to mother them or what? what are they, 16 -18 inchs tall? i do 9 under 1000hps and i would have gone to 12/12 already.
i think weed is right about the ventilation combined with the spraying and humidity. if those were mine id clear out some of those ugly leaves from under the canopy. when i grow kush in winter i get some leaves looking like that on the center plants. i clear some of the lower stuff and set up fans lower to help push air in there. bushy bitches that love to grow mold, but i love babba kush.
i run GH w/ 4-5ml of calmag. my ppms run 1300-1400 (@1000 in summer) and dont normally need to flush (except for summer) but i do flush if i ever think somethings wrong and dont know what it is.
try to get that humidity down but man i think they look great.

[Blizzin]

great thanks icbh, Yea there about 16 inches tall. So you saying you would go intoi 12/12 by now? still to early no?
