What about that last pick near the stem. Calmag issue too? I never saw that before...

I have grown a few strains this chemdawg is a stubborn one shows hard gardening skills online not a beginner plant maybe others have an easier time idk .. yea she seems to like my t8 and t12 bulbs brights and reds but I blast 'er with the mh hps setup seems to mess with her a lil more no growth really kinda odd the lights are always at the right distances as well, and I got a nice Nova led light that does not show any help either, it has bloom and veg switches .. any idea Gquebed?? The roots look super healthy I use around 5 gallon pots good drainage too, and they are only 3 foot tall MAX not overly bushy, darn leaves keep doing this .. idk either .. I just picked up some garden lime I got one in flower that has some nasty leaves not sure what I should do with that plant :/ .. should only need a cpl tablespoons each .. another one in flower she is not much effected a few leaves but nothing crazy ..

H202 33%the roots @12mils a gallon. Could be the start of something in your roots. Cal problem maaaaybe.

Not really so well as "fast"..Best to use a liquid..
When you use eggshells...Grind them to a dust after drying them completely....Then soak. I would use some of that.
What are you in? Soil? What soil?
Feed what? How much? How often?
Do you pH the ingoing?
Skip the Hydrogen Peroxide thing!!
STFW?
NOT a "root problem" Plant isn't drooping or dying off....
He could be locking Ca, in what and how he mix's his feed.
Could be a starting pH thing but, doesn't quite look it....Same for a build up...BUT, it could be a bit of a combination of these.
Depends on how he answers, to get a clearer picture on those.
It could be as simple as the soil isn't charged with enough Ca....(back to the beginning)

if thats the issue....what will adding more Ca do for the plants?
like, i often see this on the forum, and some are using great packaged nutrients, with sufficient Ca, and always told to add more because its a Ca problem. seems confusing
thanks

if you're getting a deficiency due to a lockout from an over abundance of another nutrient, you want to leech your pot, pour about 4 to 5 times its volume of water through it, add light, ph balanced nutes to the last gallon, then let it dry out till it needs water again. plants have receptors inside of them that the chemicals in nutrients attach to, but more than one type of nutrient can attach to these receptors. if you have too much calcium or potassium they will block off the receptors that Mag would bond to, so no matter how much Mag you add, it won't help till you remove some of the cal and potassium so the receptors can be open for the mag, in fact, if you keep adding the nute you're deficient in, you can cause a chain effect of other lockouts, so don't just keep adding more of something, figure out why you need more, and fix that

There are not to many nutrient lines that actually have enough across the board - in my book.
The soil has to be right too...big factor.
Thing is Rog. I find you get more pH troubles from "flushing" that heavy! You don't need to. You can leech for like a 1/2 gallon of run off and be fine. I still don't like to do it that way.....That's the old school Jorge way..
The problem I found with any "flush" is that the soil stays wet for days after. When you water soil. the pH drops around a whole point or more. As the plant dries back out, it's rises back to the soil pH. If you "flush". The pH stays low long enough to further effect the plants nutrient uptake. It takes longer to show actual recovery then the way i like (now).
I like to water it out with a little Ca/Mg added (pHed). Like about 2 ml per gal. I do this for 5-7 days and the plant rebounds quickly. It takes 5-7 days for a soil plant to show any change. I've always seen any expression of blocking/pH trouble. Disappear in that time as expressed by the new growth...
I watered with Ca/Mg added because I use RO. At that point, I wanted the buffer in the RO water.
I'm so set in "my" ways. I forget that many don't RO.....

The plants have been responding best to my t8s and t12s esp in veg any ideas on that? One plant in flower right now looks pretty toasted I am going to trim roots bigger pot give it a good nitrogen boost if the roots look really nice and white maybe this plant wants bigger than a 5 gallon pot?? I am keeping them under 3 foot with some proper lst training the strings are not choking the plants either. Soil I reuse my soil it has a good shot of peat and decent outdoor dirt just a tad of sand and some used up miracle gro soil no nitrogen left in the mg soil so fine there I use Fox Farm trio usually keep it within a cpl tsps once every two or three waterings and with the nitrogen the flowering ones are cut back to a quarter tsp or so .. veg ones good shots of all but a lil more nitrogen I did not realize until recently the trio does not contain cal mag maybe that is it?? When the plants are in there first month they show no symptoms until they hit about a foot tall then the leaves take a beating the bulbs keep the growth good on the tops .. weird thing is is my other cpl in flower appear fine cpl bad leaves but going fine they are almost 3 weeks in flower .. ones in veg in 5 gallons are a lil beaten up half and half I already sprayed em all for rust issues last time I looked the roots had no brown all nice and white .. I got some citrus trees in the house they are just in a south facing window very low maintenance I just fed those a quarter tsp of miracle grow they grow well they get a few spider mites I will use either floramite or avid one year avid and another yr floramite .. proper waterings past cannabis plants were not that picky and responded well to my hid light set up..the sour diesals I had before were not much work that was when I was growing with miracle gro the mg was too much nitrogen only problem overall with that .. my ph tester when soil is damp wet it is in check I have to get the ph tester working by dipping it in the ph down then I test the ph water then the plant I keep the tester clean it works fine. Leaves look good besides the pics above they start doing that eventually, the one in flower is in rough shape .. my two in veg not too superior either ..

Yup - lack of Ca.
You would do better to use fresh soil or learn how to recharge soils with new nutrients - organic ones. That includes Ca. and you have to "cook" the soil for 2-4 weeks...
Skip reusing anything that was MG soil...
MG ferts at 1/4 tsp per gallon - will function - NOT SUGGESTED! Scotts owns MG and has admitted in a press release. that MG soils/nutrients are meant to screw with cannabis
The rust or necrotic spots will never recover. Look good, clean growth in the new growth. Soil take 5-7 days to show any change.
Forbid 4F is better then Avid or Floramite!
I'm not a fan of FF nutrients.....I suggest a change.....Pick carefully and don't start any increase or change to "bloom" foods for 2 weeks after the "flip". Depending on what you use. 1/2 and 1/2 veg and bloom for week 3 and then 100% bloom.
Good luck

Yea I only use the MG on my citrus plants not the cannabis like an 18 9 9 kind of blend. Would a fish emulsion with like 5 10 10 be better than FF trio?? Like Alaska Morbloom OK?? Soo I am prob going to have to repot the bad plants try to reveg 18 plus hours bigger pots get the calcium loads up like you described earlier? A magnesium blend will not hurt either .. doubt it has any boron manganese issues?? The thinned out one in flower COULD be toast right ..

Btw could adding say fruits and veggies mixing it composting indoors in a large container help fuel up my soil maybe get some earthworms in there or would it get pretty foul waste of time?? Good nutes and micros can't get my soil up not with cannabis is this causing issues too? Thanks.

Good fert NPK ratio 3-1-2 = 3 parts N 1 part P 2 parts K or a multiple of that like 6-2-4 , etc. cut it to be the 3-1-2 and use daily.
Dumping things in your soil? They have to be composted first. Then mixed in.
Reveg that late ? might as well finish it out and start with fresh soil etc next time.

I should be getting enough boron and manganese in the trio right? Soo prob kill her no revegging that one?? Most the fan leaves are fried on her think she will make it in flower?

Dr. Who .. see this is about all the leaf structure she has .. what now still flower she still has well over a month to go?? And here is a pic of my healthier plant BIG diff they were all fed the same but maybe depends on soil structure idk .. you are right though she is too far in flower buds are already bulking up slow ..

Almost looks like my hps bulb 600 watt pissed her off due to weak nutrient(calcium) loads right those leaves seem to get worse when I slapped it in there for a few days .. distance was good even lower leaves same story so not a heat issue weak plant can't handle?? I put the flouro tubes back in a shit ton of 'em .. I always dry sprays before throwing them back under the lights as well.
