[Rp365]

Morning this is the older leaves on my Acapulco gold I thought it was calmag def so I have added it to regular watering and foliar once a week not seeing any improvement more leaves everyday.

On ffof 5 gallons pot ro water as neccassary twice week feed of gh flora 3part
Water at ph 6.2
400 watt mh 18/6 but gets residual light from nearby hps. 20/4
Sorry I do not know soil ph if I measure runoff can we get soil ph?

any Ideas?

Any thoughts ?

Yes, get a run off pH reading. I suspect your pH may be out of range causing a nutrient lockout situation. One we know the pH we can go from there. Also, what strength are you using on the nutes?

Thx muddy will get you that reading shortly I am mixing the nutes at 3/4 strength of instructions will also get exact ml and etc

Also, how old is it and if you can, post a picture of the whole plant in natural light so we can see the true colors and where the affected leaves are on the plant.

Dwcocha thx I talked to a4 via pm plant has nute lockout I have done a flush ten gallons will try to buy some sledge hammer today and see what that does thx for looking in

The run off of 5.8 with feeds of 6.6 means your actual soil pH is somewhere around 5. That means you're in a nutrient lockout situation. At that low pH your plants aren't able to uptake much of anything except a few trace elements. The brown spots, crispy feeling leaves, and red stems are all symptoms of a lack of both P an K caused by the lockout. I see you did a flush. I hope you pHed your water before doing so. You will also need to add some lime to your soil to help buffer the pH. The fastest way to raise it is to use some hydrated lime. Hydrated lime can be toxic to the plant if too much is given. Use no more than 1 tablespoon per gallon of feed. Wait about 4 -5 days, then check your run off again.

I wish there was a "Don't Like this at all" button, all these guys are pros. I am sure you'll be right back on track. Strength and Honor
