Need help plz

Let’s see a pic of the entire plant

 

Magnesium def!!!!! Give her some Epsom Salt or Cal-Mag!

 

Is that soil or coco?

 

Looks like soil …..

 

Agreed!! Especially if it's fox
Farm ocean forest they deplete on mag quick! 30 days tops I get without feeding. Around that 30 day mark I normally begin to add grow nutes Ronny water.

Looks like promix. If thats' the case, you should be feeding it to runoff every day. Check that runoff pH and EC, could be leaning on lockout. Peat breaks down and it gets to a very low pH at the root zone.

 

Nute burn if anything. Feeding her like she had lots of light but a 200W CFL isn't near enough to use up even lower levels of nutes.

Low Mg or N will cause yellowing over the whole surface of the leaf and not just the tips and edges like you got there. Tossing more salts like CalMag at it will only help burn it more.

Get more light on her so she can utilize what feed she has and it'll grow a lot better. Not sure how your light is set up but should have a good reflector to direct all the light at the plant and not just hanging there with most of the light lighting up the grow space away from the plant. I see a lot of CFL growers doing that.

Just tin foil on the back side of the bulb will do a good job of getting most of the light onto the plant.

Find some more light(s) before you flower her if you want a decent yield. Even a 150W HPS security light with that CFL would do a decent job. A 400W Super HPS or decent little LED would be better.

Good luck!

 

That's a soilless blend then so you feed like hydro. I use ProMix HP that's soilless. No coco just peat.

 

Those are both soilless mediums and neither should be treated like soil - they are drain to waste hydroponics.

 

...because your runoff is probably like 4.0. You need to check the pH (and TDS/EC) of what is coming out. Go feed your plant, then collect the flowthrough and report to us.

 

Your pH is too high going in - that's soil pH. Should be 5.8 or so. I suggest you do a flush with 1/4 strength nutes, pH'd at 5.8. Good luck.

 

Hey lambokid,I hope you calibrate your pH pen more often than I do, which is once a week. You'd be shocked to see how much they can drift, and what the actual ph of the solution is.

 

That's the exact reason I use the pH drops.

 

Clearly they don’t.
