[nick slaughter]

27 days old

Started losing fan leaves 2 weeks ago and now spreading at a faster rate. Cal mag has been used The last 2 weeks and tiger bloom 2 days ago. Been watering with distilled water twice a week all nutes 1/2 strength

Nick-- lower fans will start to fade out like this during bloom, but as noted, you say the pace is increasing? I suspect the bloom nutes may help, P and K are now in full demand, and Grow doesn't have the right ratio for this,... I do see some tip burn, telling me nutes, even at half str. were right on the edge of tolerance,.. OF is a rich soil, and though I don't see signs of it, often, their soils are badly off pH right out of the bag..talking low 5's here! ...some folks get lucky and have bags that are seemingly OK,... watch the tips for any progression of burn; keep on the Bloom nutes, half str.,... I seriously recommend getting a soil pH probe for direct in-pot measurements.... the Accurate 8 is a good model .....here's why: off pH messes with nutrient uptake, which in turn causes defc. symptoms to start,.. deficiencies happen because either a lack-of certain nutes, off-pH lockout of them, or toxicity from way too much of the/salt build-up..... fixing these goes in different directions... lack-of is simple, just add more.... but off pH and toxicity need to be addressed by fixing that first, adding more nutes to plants in that state will make matters worse! Having the pH probe can help determine which is the case,... do you have a pH meter (liquids only)?

What @Waira said, stuff is super concentrated, and i have used it for almost a decade now. Well up until about a month ago.

1/4 strength will get you through in barren soil mate, and using the Ffof its a little hot to begin with. I too have seen those exact images in my own grows from the tip burn to the faded fans.

pH is important and you are in the need of bloom nutes now. BE WARNED, if you are using tiger bloom its super acidic. It will drop the pH of any liquid its added to so i assume it does the same to the soil. Get you a meter and test the soil, i know it means spending more money but when you look at the savings in the end its well worth it.

Eventually over time they hand and eye becomes accustomed to growing and such devices become only needed in an emergency to understand something that is new to a grow.

Thanks for the replies definitely going to get ph meter. Today I didn't notice anymore yellowing of leaves just the small rust spots

 

[nick slaughter]

Ph was at 6.8

what brand of pH probe? or did you mean meter...
