So i am using fox farms and watering with pure water that i ph to 6.7. what is wrong with these plants. they looked amazing until i put them outside. Also my flowering plants outdoors look like garbage. What i am most concerned about is the first pic. This is a mother inside the tent that was doing fine. Im think maybe i have thrips? but im not sure. Ive been looking around with my hand lens and i cant seem to find anything. I think it migh also be the tobacco mosaic virus? if thats possible. Or maybe even broadmites. I know the plants that are about 8 weeks into flower i nute burned for sure. I am also very concerned about my 9 kaia kushes that i started from seed which are the plants that havent shown their flowers.

just looks burnt. nothing you can do really at that late in flower. and by pure water do you mean RO? might have some calmag deficencies or it could even be locked out due to an imbalance from over feeding.
 
Do you have a scope with 30x or greater zoom? Its not broad mites, its most likely rust mites. If its rust mites, my very 1st post was about rust mites, scope it out...
 
Yes I am using r/0 water. But I am really concerned about the plants that aren't flowering. I have a growers edge hand scope that I use. I didn't see any mites or eggs upon inspection. But I will again later. What really concerns me is the first few pics. And I do use cal mag

You must find out if you have any micromites. Its hard to believe this is nute burn, you would really have to be dumping some shit on em to get this effect. Its falltime its time to tackle it before winter if you have perpetual grow. If you dont have perpetual grow then you need to bomb your house at least and treat your yard, they will lay dormant till next year and come right back
 
ive seen that before on my plants im trying to remember what caused it. are you inside under a low intensity light (like t5's) and then moved out into the sun? if i recall i think the difference in the light intensity can stress under certain circumstances. but the yellowing/rusting leaves looks either like an imbalance and the plant is not uptaking properly. could be a calmag issue but probably not unless you overfed them with something and threw all the nutrient balances out of whack. creating a toxicity of one nutrient can lock out another.

are you giving them anything other than just the foxfarm soil? are they freshly transplanted into new soil when you put them outside or do you just move the plant outside in the same pot?

do you have a fan on your plants inside before you move them outside? what are the conditions inside vs outside like

leaf curling like that i think can be overfed plant. light too close to the plant (or if its moved from low intensity to sun light same difference, too much light initially, plant will bounce back after less than a week and thrive not a big deal if thats the case). i think if you have a fan blowing on it too strong it can do that also. or maybe if its really windy outside. as far as the tiny spots on the leaves doesnt look like mites to me, and im sure you'd be able to see them. the problem with buying bagged soil is they're all sitting together. different brands together. and some brands come with issues such as mites and gnats. im pretty sure ive read in the past about foxfarm coming with pest issues in the bagged soil.

i personally use roots natural/organic and dont have any problems.

to be honest with you i never ran into any issues in soil plants until i started using RO water. its too stripped down and i feel it leeches the soil plant. always had best success with unchlorinated tap water (maybe just use a filter such as hydrologic's tallboy to filter out chlorine). im in my first experiments with DWC now and had many sucessful years with soil prior. i still keep my mother plants in soil and ive been having some similar issues which im contributing to the RO water. i'm going to start dosing them with the same synthetic nutrients and calmag as i do in DWC to see if it helps. if not i'll just revert back to straight tapwater for soil plants. if theyre outside just give them hose water.

the tap water where i live is terrrible. I was using a tallboy before then i noticed these problems. Before i that i would just buy r/o water. Then i got a tallboy and started using that and noticed burnt tips. So i then invested in an r/o system. Now the plants flowering are basically done so not really concerned just thought they might help diagnose. The first 5 pic am what i am worried about. they were inside under a 400w mh and did not get transplanted. I think heat could have something to do with it but has been the same temp as it was when i started them as seedlings and they were flourishing. idk stumped here. Getting batteries for my hand lense tomorrow but im 99 percent sure its not mites. also the roots look fine aswell so no pythium or fusarium. IM really convinced its tmv just because i roll splits with american spirit and im about 15 feet away from them sometimes when i am smoking. Im def switching to promix bx for outdoors just because the the start with nothing type of thing. I definitely fucked up the flowering plants by giving them way to many nutes and my shitty filtered tap water.
 
well ill cast my vote for overfert and heat combo. just transplant them into a bigger soil only bucket and dont give anything extra and i expect it will work itself out over the next couple of weeks. make sure if its hot you arrent letting the soil overdry inbetween waterings
 
how bad is the tap water, is everything dead in your yard? plants are pretty resilient in soil. in a hydro setup bad water could definitely cause an issue. but the water would have to be bad enough to kill your yard in theory to kill your cannabis. given cannabis is just a weed. good soil buffers automatically and its very hard to damage a plant. assuming you're using non-synthetic nutrients, they can take a while to break down and 'feed' the plant. which can make it easy to overfeed because you dont see instant results as you may with synthetics. most bagged soils also have enough to carry them for a good month before you need to give them anything additional. as said before i use roots organic when i do my soil grows and i start them off in red cups. 2-3 weeks later ill bump em up to 6" mesh pots. another 2-3 weeks later 3 gallon pots. then another 2-3 weeks later 7 gallon pots for flower. the plants never show any signs of deficiencies. i dont give em anything other than water.

however in flower you can mix in a little extra fish bone meal, blood meal, kelp, and azomite. or use it as a top dressing like 1 tablespoon a week of each for the first month if you feel you need to push your plants a little harder (only in flower and only when they are established)
