Firstly , maris dont hijack threads mate it confuses people and is very rude, we will deal with you later.
Now your problem(letstrip) is salt burn. It causes the rust spots, upper and lower shade leaf yellowing as the plant can no longer take up N and other trace elements. The rust spots are...
And your right fred ;). When dope plants flower they need large amounts of P and with those red stems the plants are starved of P. Get some hydro flowering nutes.
It looks like you blasted it with an AK47 , what the fuck happened bro?! That plant didn't just go like that over night. Yes its completely dead as shit .
Start again and do more research first.
Thats right with this sort of coco mix you only use hydro nutes every watering ,no ph adjustment and no guessing, quite simple really with amazing results. Dries in about 3 days med size pot. The mix/feed with no guessing have the plants healthy so the consumption is high and fast. Also to get...
Bro that looks like a fucking horrendous transplant. What happened? did you rip it out and shove it in the new pot with a she'll be right attitude?
All you can do now is stop feeding /watering, raise light and hope for the best.
Reduce watering ,feed them hydro veg nutes and use pro coco mix only next time, you cant just throw a mix together without experience and expect it to work. This coco is made for growing dope
Your making something easy seem hard.
Just use canna terra in coco every watering at the max amount on the label, veg and flower. You cant use a chart as plants consume more or less at different stages of growth and ambient temps and you must go by eye and feel of the pot.
Its stem rot and looks bad. It could survive but wont ever get to its full potential. Reduce watering, no spraying, remove all lower foliage, blow fans on the lower main stem 24/7.
Its not dry. This is what happens after a terrible transplant of an already sick plant that was not root bound or ready for re potting.
Its fucked ,start again and next time only re pot a healthy root bound(or close to it) plant.
No. Plants don't reveg from stress bro, they reveg due to an extended light period. If you think the ph is ok then i would say the excess K and build up of salts at this late stage has stopped the uptake of N and other trace elements.
All you can do is hope for the best as this is a major issue. Next time put them in holes in the ground as it drains better and in drought holds water longer than a pot.
All the rain has caused the medium to stay too wet too long and now they have a major root system issue. Yellow new growth is usually problems in the root system. Also being in all that scrub doesn't help as no sun or air can get to the pot to help dry it between waterings.
