3/9 plants having leaf issues despite all 9/9 in the same conditions

GrandpaSamstarted grow question 5y ago

Is there a way to remedy this without flushing my pots (i dont have the space or privacy)? What would the best way forward be considering I am entering week 2 of flower today? Keen to remain 100% organic but happy to break that rule to save these plants from going under.

You have a potassium deficiency. Your plant is going into flowering good and really hungry for more potassium and phosphorus to make your buds. Would increase potassium levels. Good luck

That looks like a calcium deficiency. First few weeks of flower the plants grow alot. Add a calmag nutrient.

Light spots on upper leaves So I noticed some light spotting/discolouration on the upper leaves of Samus. I've never seen anything like it before but is it normal or something to freak out about? Are the leaves mottling?

Normal or should I be careful?🤔First time I see these little dots on the leaves, can anyone identify them or is it nothing to worry about, as I'm thinking? 🧐🤔

Auto seedling discolouration This discolouration has appeared on the leaves of one of my two gorilla glue autos, it has been there since the first true leaves which makes me think it could be genetic? I’d like to know if anyone has more information on the cause or if anything needs to be done about it.

How does this site work exactly? Also, couldn’t Figure out the yellow spots/edges that appeared on lone plants leaves. It didn’t produce anything worth mentioning in the end. Too much or too little Nutes? Thanks for any help.

Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!

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?

Hello. When I watered 3 days ago, I saw some brown spots on the lower leaves and thought I had got some nutrient solution on the leaves but now it's on the next set too. Any idea what is going on? All 3 plants are being treated the same. Thanks Chuck.
