Been growing this plant using fox farm dirty dozen soil feeding schedule. I’m using a mix of fox farm ocean forest w/ 30% coco coir/perlite added. started at 50% nutes now up to 100% feeding every other watering

Planning on starting flowering within next couple weeks.

growing under led. Been adding 4 ml/gal of cal/mag to every feeding. Always ph the water to 6.5

Any help would be appreciated

That coco coir will/is giving u trouble. Next time just add perlite to the soil.

That’s a calcium def. most likely not caused by lack of calcium but conflicting media.. only way to know is to increase cal/mag and back off the feeding to 50% Unless it was yellowing before the increase in food otherwise stick to 100%

I am using the full fox farm dirty dozen kit. I stared with 50% ppm using a meter. I transitioned to 100% about a month ago. I water roughly 2 times per week depending on the plant and weight of the pot. I will attach a picture of the ppm chart I am using.

I have been using the exact ratios according to fox farms. Should I feed a high dose of tiger bloom (2-8-4)

or should I find I way to directly add phosphorus?

I think if anything there may be too much P which can cause multiple micro-nutrient lockouts. Excess K does that too. When flowering more of both is needed at first then less P and more K as flowering gets past the stretch. Durring veg much less is needed and that's when too much causes problems.

Make sure to read down the left sides of both for problems caused by excesses.

so should I not follow the fox farm schedule?

thank you for the help.
I HAVE NOT started flowering yet.
therefor, I have only used big bloom and grow big along with the other products recommend along side them. Big bloom was only added in my last feeding, after symptoms started showing
How would I know when the right time to start adding phosphorus?

I am having a hard time finding a feed schedule based on using distilled water as a base and LED lights. Anyone have any advice?

I want the nutrients from the soil but better drainage from the coco.
Am I wrong? What would you recommend?

This would help me a ton if I have been doing it wrong. So many different tips online I’m looking for something that works.

I understand that there are a few people that mix it with some success, but most people have problems.
If you want to mix a soilless medium with your soil, use peat moss.......not coco.
Soil and coco have different feeding and pH requirements for proper growth and nutrient uptake.......coco should stay wet and never dry and fed regularly, while soil contains nutrients and needs to go through a wet/dry cycle.
I really don't know what to tell you about feeding or what pH is best........soil is 6.5 and coco is 5.9.
Maybe someone that has success with this method can chime in and help.

Good luck.

When I zoom in on the leaves I see lots of white specks on some of them. That can be insects so try checking under the leaves with a loupe or magnifying glass.
