Indoor grow, three varieties of seeds used. Kali Mist, Strawberry Banana and Skywalker. I am using Fox Farm Ocean and used nothing but the soil, no added nutrients. I am now using Fox Farm Bloom. My issue is with Kali myst.

All my other plants look great and treated exactly the same Even the other Skywalker plants are doing well. This one is quite small comparing to all the others and it is very yellow also in comparison. I am in day 16 of 12/12 flowering stage. I could use some guidance. First time grower here and could use some guidance.

What's the soil PH? and what PH do you feed? How often do you give nutes? and how much per watering?

I’m using the two prong moisture meter with ph and light meter. It shows high ph but the soil is ocean by fox farm and the water is reverse osmosis that is ph 6-7. No feeding in vegetative stage and big bloom since 12/12 not quite two weeks ago

I use those too. I only give about 20ML spread throughout the week of big bloom, and 15ml spread out of the tiger bloom.

You are lacking nitrogen. Nitrogen is used for the production of flowers. The plant is taking it from the leaves because it can't get it from the roots.

You need a balanced feed from start to finish.

Thank you, you are quite helpful! Q.
Should I give 20ml spread out each week throughout the 12/12 bloom? And tiger bloom at the same time and sane amount? I’ve learned a lot. Mostly what not to do ha!

start her on that mix for a week. Just mix up the solution for the week in one shot. You will have to shake the shit out of it and check ph before every use tho. Also if you water to feed in the mornings every other morning water with plain ph’d water. Base how much solution you will make for the week off of the every other day feeding schedule.
don’t mix more than a weeks worth. Each week she may be able to take more.

oh...I have 9 plants. Will I use 20ml a week for each plant or for all?

20ml per gallon of water regardless of how many plants you have. Just mix an appropriate amount. You can do it in separate gallon jugs to keep it simpler.

As it is on the old leaves, instead of a newbie, it's a mobile component deficiency. It seems phosphorus deficiency. But I would advise you to FLUSH YOUR SOIL and start going easy on NPK. Mostly PK
