deficiency...please save my 4x8 guys/gals!

[smurfin'herb]

Hello, my computer is broke and i am on a friends so i dont have my camera pic program for pics sry. im in flower and I am having two problems, one looks like a sulfur deficiency and one looks like potassium from my observations. The sulfur shows bright bright yellow on all the newly forming growth all over the plant (it starts from the leaflet base and goes up) and after a while i notice if i kneel down and look upwards toward the light through the affected growth i see thin patches looking like they dont have chloryphyll. I flushed 6 days ago and added 750ppm connoseur, 1tsp/gal hygrozyme,50ppm cal mag (r/o water), and 2tsp/gal gnatrol, then 3 days ago i watered with plain liquid karma, the problem still seems to be in swing. please note that i may or may not have added sweet right before this deficiency took place. i dont remember, but i had this same deficiency in veg when i added it it seemd like.

The next is that the lower leaves on my plants are browning and becoming brittle and falling off. The browning starts at the tips and works its way down the leaf. but note that some leaves are barley browning yet still falling off, im thinking overwatering might do this?

temps are 65 night 78-81 day... humidity 49-55 day 55-60night?idk. I will only have this computer for 48 hrs so any help in that time period is helpful. i wish i could give pics, i have a 4x8 stuffed fullllll and i gotta pay out my investors so i cant lose this crop.

first problem.
never work to pay off investors...on a grow? whats from stoping them from turning you in, besides some cash? what if things go sour?
...ok enough of that.

its probably more a magnesium problem from the sounds of the yellow. are you in soil or hydro you didnt say ph needs to be correct.
if your using tap water then you mostlikely have lockup.



thats a pic of a lockup.

u said connisuer, thats AN did you use part A&B ? i hope so. u need to use RO/distilled water inbetween feedings you will burn the plants out with 750ppm connie each water. if thats what your doing then there burnt already and you need to flush with ro/dis water to fix the lock.

more info.

ph/
water
other nutes?

your RH 50% humidity it a tad high you want to lower that as much as possible. 20-35% is fantastic for flower, dry air makes oily buds.

my ph meter broke 2 weeks ago so i use gh drops for ph, its around 6.0. I am in coco coir (bcuzz)(3 gal grow bags) and i flushed when i saw sulfur lookin def 8 days ago. and then i noticed the other def 2 days after that and it was pretty progressed when i caught it so it must of been round the same time as the other one. i use r/o water and add 50ppm cal mag to it. my feed schedule is 750ppm connie as well as hygrozyme and gnatrol. then when they need water again i just water with 50ppm calmag and liquid karma, then repeat the process starting again with 750ppm connie A and B. My legends ultimate indicas (on the same table same feed schedule/regimen) are showing this symptom but just barley. I dont know what the name of the strain most affected but it tastes orangish and smells lemon pine sol. So theres no salt build up, 80% sure not overwatering, 80% sure ph is ok. i just noticed some leaves on the bottom deficiency turn light green while browning/rusting/crisping/curling while some stay normal green color while doing the same thing. The ones that turn light green arent as affected as the dark green ones but it seems they fall off just as easy if not easier. My water is clean, my feed regimen is simple, my ph is ok, no salt build up, i just dont know what im doin wrong.

also its not a mag deficiency. im 10 days in flower and the newest leaves that arent even folded out yet are neon yellow starting from the BOTTOM of the leaf. the jagged leaf edges are still green and curl downwards back up underneath the leaf. The new growth is affected only and it feels weird, like oily kind of. its gotta be like iron or sulfur.

sounds like when you flushed it you threw off the plants osmatic pressure with its ntues and washed a bunch away, although calmag only containes 3 minerals, sensical is better, its got a-z....
you should consider RO water, or get some jugs and go to the glacier machines. thats what i do. that tap water is destroying the plants. ive seen it myself everytime i grow w/tap i get what your saying.u can even get some of the 1 gal jugs at the store, if your growing in bags you dont use more then 4 or 5 gal probably? its worth the money, especialy if your using connie.

if you do use RO follow the 900ppm feed and 3x the cal-mag

if you dont use ro bubble the water in a bucket (5gal?) atleast overnight to rid the chlorine. that will atleast help. and also use the 500-600 feed for the connie.

the tap probably has 350-500ppm and it sounds like a lock-up.

chloriene, chromine, lead, heavy metals arnt exactly friendly either.

hydro by radio (no test equipment) get some test strips or a meter fast.

Is it a HydroHut?

 

[smurfin'herb]

dunno what a hydro hut is, but i have a 4x8 table with 15 3 gal grow bags and i hand water. MY WATER IS R/O from a hydrologic 100gpd system. Oh an i use 50ppm cal mag plus not just calmag, i should really up it and add 3/4 of a tsp/ gal? thats like 150ppm.

 

[smurfin'herb]

when i flush these, how long should i wait before giving them nutes? I am afraid if i do it directly after the flush then all the salts will just go in and out of the coco because it is stuffed with water and has no more room. Right now i feed and then 3 days later i just plain water with LK and then feed again, is this a good regimen or not? Oh and whats osmatic pressure, i heard a lot of jargan but not that?

use more calmag... 5ml/gal

use a slightly higher ppm on the connie

 

[smurfin'herb]

i get 50ppm out of 1/4 tsp of calmag plus. so 5 ml would be 200ppm. My tap going into the r/o is 235 ppm and i dont use it so why would i add 200 ppm of calmag? And a tech at advanced said only use 50ppm of it. Also my babies showed slight nuteburn (yellow tips on new growth and tips curving) after i flushed and added 750ppm connie, so im kinda scared to up it. So is a full feed,water,full feed,water regimen ok to do in flower in coco, or will that burn them? sry, new to indoor.
