Magnesium Deficiency ? How can I fix it ?
tiasmaaastarted grow question a year ago
got a little deficiency (maybe burned? but I think not).
I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).

Never tried myself, but never understood those soil and coco mixes, but ph 6.5 could be too high, 6.2 guess would work better.
Now to me it looks like nute burn, a bit too much nitrogen, that blocking absorption of magnesium, so you have first signs .. would not worry, cut all N out, few pk feeds and I would plan plain waterings before chop, aka flush.
Looks nice !

тут только 2 варианта. это либо недостаток магния либо не достаток Potassium. очень похожи их симптомы. но точно это не передоз.

Your pH should be at 6.2-6.3 for optimal growing according to your nutrients.
Looks like you over fed something to me and it locked out the potassium. It’s not a magnesium deficiency. Magnesium deficiency starts at the bottom and will severely damage the leaves and work its way up as it’s a very mobile nutrient. I think you should just reduce the nutrients your using slightly and the plant should start eating normally again.
The plants show mixed signs of potassium deficiency and nutrient burn so that’s why I am saying what I am.

I think the problem is your pH here... get that down to 6.0-6.2 and both calcium and magnesium will be more available to the plants. I'd also suggest you buy some fresh calmag but only use it once a week as you don't want to overdose and get a toxicity of THOSE nutes! Your grow looks gorgeous and you've got quite a while yet to go so it would be a good investment...
Good luck!

Nutrient deficiency or surplus?Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F

Spots and yellowing on the leavesGood evening I have an autoflowering at the eighth week and recently yellowing has begun to appear on the leaves that I don't understand if it is the leaves that go towards the natural end or a problem of burning of fertilizer or even a fungal infection.
