A deficiency ?

[st0ne]

Hello,

I picked up some Kush clones a week and a half ago, and have been trying my best to nurse them back to health. When I got them they were stressed and also tainted with thrips! gah!

I planted them in beer cups with high porosity Pro Mix, and have been very sparingly on nutes. The nutes I'm using are a local hydrostore 3 part. I've fed them twice now, once with bloom and the next time with veg. The PPM was between 600-700. Since then I've given them straight water, with the runoff being 500-600 with a pH of 6.3. Water from my tap is slightly basic at 7.4 with a PPM of 100.

I've also given them multiple foliar sprays of diluted Thrive Alive applications. I was dunking the clones in End All for the thrips, until recently where I acquired a systemic pesticide. I've been careful not to burn them. Regardless, the infestation doesn't seem too advanced; I just want to knock them out before I get into flowering.

In the beginning the humidity was only 29%, but after installing a humidifer I've got it up to 40%. Temperature is between 26-28 degrees celcius. A 400 watt HPS raised a good 2+ feet above canopy, with lots of indirect air movement.

Symptoms include intervienal chlorosis, short stature, purple stems on new growth, visable twisted growth on some plants including single leaf mutation.

The plants have been sick since I got them, although a few are doing well. The only thing I could think it to be is shitty nutes perhaps? pH? Underfed?

Sick plant,



Healthy plant,

my very first guess....ph lockout. You've fed them everything so ph is reallly the only logical answer if you really do have the thrips under control.

Are you correcting the ph of your tap water before you water with it? Say to 6.5 before you water with it?

Overfeeding and pH is wrong, try straight pH adjusted water for a couple of days

Are these clones from a re-vegged mother plant as the growth structure seems alittle off for my liking? Also how long have they been rooted for? I would stick to ph'd water at around 6.5 like weedhound stated and wait for 5-7 days to see how the new growth comes in.Patience is what is needed here my friend and keep the chemicals away for a few days like stated.

Peace,
Jazz

Pretty much what everyone else said. What stands out to me the most is that you said you watered them with "bloom". They're not flowering so I don't know why you would do that. Unless it's a coco-a and b for example and you're calling one bloom and one veg.

When things are not going well, adding everything under the kitchen sink is usually not the answer. Sounds like they were in pretty bad condition when you got them. I would also chill on the thrive alive foliar feeding. That stuff is pretty strong and they're so small that even if they needed it, it wouldn't be that much.

I would say to check the ph of your mix and give it a light flush of plain water for a few days and then a low dose of the veg nutrient. They should bounce back.

Good Luck.

I'm still trying to figure out why some plants do the purple stem thing and others are just cranking out nice thick green stems. So goes life.
