Potassium deficiency?

6ix6ix6ixstarted grow question 4y ago

Please help me identify the problem. I’m thinking about potassium deficiency because i add only bio bloom and i dont have top max. Should i add some PK? The problem only with the top leaves, bottom leaves are fine. The other plant in same soil and same nutes is totaly fine

Your instincts are spot on .... potassium! Should you add PK? Yes! Your pH is perfect so if there was enough for her, she wouldn't be showing these signs... and it's about now in the growth cycle that plants are REALLY hungry for both potassium and phosphorus ... so get some to her pronto! Good luck!

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Saw this first day of 12/12 Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.

Light, nute, wind or heat burn?Im getting some browning on the serrated edges of the leaves, moreso on the upper fan leaves, but not on the sugar leaves, with some cupping of the upper leaves and the ones directly under the light are getting a lighter color overall. Any guesses? Light, nutes, wind or heat?

Is this heat light burn? HPS 600w at 20cm Is this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).

Looking droopy/yellow due to light burn?Looking like light burn (most intense from the top) and maybe overwatering? I am trying Nectar for the Gods #4 soil for the first time, and I just put it in a grow bag and put the clones in it. Unsure if I was supposed to prep somehow beforehand.

I have been having trouble with my leaf tips and edges appearing yellow and then turning brown. At first it was just the bottom leaves that were affected but now more of the top leaves have the burnt appearance just not as extreme as the lower leaves. What can I do to fix this?

Esto es normal? Floración - Double cookies auto I'm in my last week of flowering, and recently the leaves started turning like this very quickly. Is this normal? Did I do something wrong? I have 4 autoflowering plants that are in the same state. A lot of yellow leaves have been falling lately, but the buds aren't maturing.
