After a few days this shit began to appear on 1 plant. Only a few other plants have spots but none like this one. Its pretty localized to that plant. I think it might be an insect problem but I can't find any insects or larva. I took the ones out of the soil and thought I saw a few thripes. I also say some flying thripes about 5 days ago and killed them all. The ppms in the res are now at 60ppm in tub 1 and 40 in tub 2. The plants otherwise look healthy. the large one shows no signs of spots or necrotic spots so I know they are getting enough calcium and nutes. The large one however seen in the picture has some dark edges on the lowest most leaves.

I have a Hot Shot Strip, the one OpieYutts suggests. What should I do?

The ph is at 5.8 for both so no problem there

Could this also be due to the fact that I am only running 60 ppms? They got a little burnt on the edges before but could the spots be from a lack on nutrient like P or K. I went up 30 ppms today already so I know I want to increase slowly. How many times should I be changing out the res? I filled the water to the 3 gallon mark about an inch from the top. and the roots look nice. lots of new white ones.

Note: on the infected plant the top leaves are looking great with no spots at all. Is the plant taking nutrients from the old leaves to the new ones?

[Weedhound]

Yes I certainly think both things are possible here Jeff...not enough total ppms and the plant is drawing on the older reserves to compensate.

I change things out completely once a week but draw off SOME old solution and add new at least once between then as well.

Since you are using tap water I would put them on approx 150-200ppms Pro Gro and see what they do with that. I honestly don't think you can get into too much trouble at that number. I still don't think you need any CalMag is you are using tap water but if you have Liquid Karma you could toss in 2m/gal of that as well.

Edit: let me clarify....thats 200ppms of Pro Grow IN ADDITION to whatever ppms your tap water already has in it.

Thanks Weedhound. I think I was being a bit too conservative with the nutes. I am adding ppms slowly back into the res as not to shock them. they are up to 90 so I doubled in the last 24 hours. I will add more tomorrow. I put 3 drops of Superthrive into each res and will be using some diluted Colossal Bud Blast tonight as a foliar spray when the lights are off. both products I heard are awesome and I think they will like the extra nitrogen on the leaves. I did add a few drops of LK as well as 3 drops of cal-mag in the res for good measure.

Cheers

Holy S*IT that helped. they both ate 20 ppms out of the res so they def. needed it Took the big tub to 130 ppm today and the small to 115. They look perky so I will folair spray again when the lights are off with the diluted BudBlast. Tomorrow I will take some of the solution out of the res since its midweek and replace with some fresh H20 and maybe bring the nutes to 150 if no signs of burn. Thanks for the advice!

Cheers

Now give it about 48 hours before you increase your number again......slowly does it. It takes about 24 hours to see a change so if you're adding things TOO quickly by the time you see a problem more damage is done than them going a little light on the chow for a day.

And lets see a new pic of them when you can swing it.

Took these 10 mins before they sleep.

Look a ton better. added another 6500k bulb and a 2700K one I had lying around. so now they have 4 6500k 26w cfl's running at 100w each and 1 2700K 26w cfl running 100w too. 500 total watts.

They have a fixture at Home Depot I saw. Flouro X or something like that. it replaced all their MH and MV outdoor lamps. It claims that at 100w its equal to 1000w incandescent light. it runs 6500K as well. Looks like a beast and at 60 bucks, seems pretty good. Thoughts?

The stems are stretched when they went into the dome from seeds but i figured they will be in 6 inch net pots when they flower and I can just bury the stems with the clay rocks until the first leaves saving 4 inches off every plant.

I think I want to build some recirculating dwc buckets. i have an ebb and flow right now for the flowering but I love those dwc units. I will be getting into my new place and will build a proper veg and flower room.

I do have a nice 6 inch inline fan and a 600w hps bulb, digial ballast and awesome hood. i want to add a few 6500k bulbs during flower on the sides as well.

look's like you have it going you way:wtf::wtf::wtf::rasta::rasta::rasta::thumbsup:

[JeffersonBud]

Thanks! In the wee hours of the morning, when the lights turned on, I changed out both res. It has been 7 days and now they are on thier second week of veg. I brought tub 1 to 140 ppm and tub 2 to 120. It is now mid day into their sun and they look great. Leaves are not over perky but straight out. They also ate another 10 ppm a piece but i will take WH's advice to wait 48 hours before upping it again. No signs of burn and I did spray with the Colossal BudBlast last night. 3ml of LQ and 2 ML of cal-mag were put in as well. i need a better ML beaker. The GH eye dropper I got with the liquid PH test kit, before I got my meter, I don't think is very accurate but maybe its just me.
