Can Anyone Tell Me WTF Is Happening To My Plant?

shes been doing really well, nute ratio 3-1-2 shes 9 weeks into veg.....

i have to say, im not sucking out half as much air as i should be.


is it just lack of light im seeing ?

or nute burn ?

i was planning on drying her out, then giving her some plain water....

here is an even better photo of a fan leaf that has just dropped off.....part of it is VERY crunchy, the other yellow part tears incredibly easy.

im thinking nute burn, lack of light , or ???

due to the fact that the veins still look green when the rest of the leaf is yellow i would probably say mg def. but i would say check ur ph first. is it starting from the bottom and working its way up?

i will check my ph over the weekend, and yep starting at the bottom.

well if its startinf from the bottom n working up its probably a N deficiency. but check to see if the veins remain green or if they yellow at the same rate as the rest. if the veins r green n the rest is yellow then its a mg deficiency. but remember to check ph cuz that could just as easily be the problem.

also just know im no master gardener i jus like to give insight cuz i know sometimes its hard to get ppl to reply here.

nice one , thanks fella, ill keep a close eye on her , check the ph and ill keep an eye here on the thread.

no problem. keep me posted on the lady. i love to see how things turn out.

well, im going to flush her, dry her out and give her some good ole plain water, do a ph run off test, and then 'maybe' look at doing something to help with this possible mg def....

incidentally, im seeing 75% brown crunchy leaf and 25% yellow soft leaf

if anyone else can offer an opinion ?

after you flush i would hit her with a 1/4 to 1/2 strength nute mix. just in case if it is a def ur not removing all the food she has left. if anybody else can give a second opinion on the mg def the best way to help is foliar spray some epsom salt

a few more photos....

im starting to think its definitely mg def after looking round, so, if that IS the case, im a happy man again, it seems easy enough to cure

BUT if anyone can PLEASE help me ? this is my 1st grow.

can i get some more opinions please ?

Might need some iron & zinc. I put some in my plants if I start to see yellowing to curb it.

ive just treated her with some epsom salts, because i thought and was told it could well be a mag def.

i just ordered a bottle of bio essentials now anyway....

looks like ph

the water going in is just below 7, ive ordered a digital ph tester and digital soil tester.

so far its been suggested that its mag def, zinc and iron and ph as well....and someone also said it could just be lack of light.

im starting to wonder who is correct......ill just have to keep trying, tackle each thing at a time until i see some improvement

ive added some epsom salt, and i have coming a digital ph water test kit, some ph up, ph down, and a digital soil ph tester and a bottle of bio essentials [ trace elements ]

ill update in a week.

I see this alot and in my experience this seems to happen to the inner leaves that are usually near the main stems or under a very dense canopy.... Sound familiar?

I think this is just a light penetration issue.

Unless you can provide some more plant pics of the affected plant and try to include all angles so that i can tell for sure.

BUt it did look like you had some burn on some of the leaves in the background of one of your pics.


Whole plant pics will help to diagnose fully for you.

ill get some up later, also, ive only been using a 3-1-2 nute ratio.

i was considering changing to a 20-20-20 ratio.....does that equate to 2-2-2 ?

I think we are seeing a picture her, mag def, zinc, iron, nitrogen! Underfeeding maybe?!

So even if it was mag deficiency mainly, without the right levels of the other ferts its not likely to be cured with just mag. Get your trace elements sorted, think thats the bioessentials and increase the ferts bit by bit maybe with a touch of mag - if it is not present in the bioessentials or your water (test your water ppm to find out)!

I add my seaweed or trace elements once every few waterings as the soil dosent need very much, can be easy to overdo the trace elements a lot of times, one or two applications should be enough for most of flowering.

As always try this first and await the results. Bottom leaves dying or going yellow (as in one pic) whilst the rest of the plant is green and healthy suggest a deficiency. 3 1 2 is a touch low in phosphorous but dont change this yet, try increasing the ferts and trace first.

When i first flushed properly i noticed it left hardly any ferts in the soil, plant started to starve in under a week, now when i flush i add almost a full strength dose of ferts and trace elements back to replace what was loct from the soil. It is easy to get out of balance with flushes and ferts, consider this too. Good luck.

2 2 2 is the same as 20 20 20 yes. Maybe a better nute ratio than 3 1 2 for veg. Peace
