thank you man ! ,you think there is still chance on my plant to reheal ?! also 1;6 ratio so for 700 ml i would use 100ml fert and rest is water
?
I'm a first time grower. I'm in the flowering stage right now. I use pre-fertile organic soil. I also use organize nutrients That's fertilizer from botanicare brand. During the beginning stages from seedling to veg, (In your situation) nutes is nedded. Since your soil has (no added nutes), you need to give them nutrients. I used cal-mag, silica blast, pro grow, liquid karma, pro blend tea, superThrive (Walmart), etc. ( whatever botanicare advices) during the stage your plant is in. Each nutes has their purpose. If you choose to grow with botanicare, or any organic nutes this is what I have to say.
My advice use less than advised. (Portion 1/2 or less than botanicare advise you feed your plants). Pay very close attention to your babies. The second I saw discoloration in the fan leaves is when I cut back to basic spring or distilled water.
** in the case of dismay feed them ppm:0, pH6 (drinking water).
Also know as much as you can about the strain that your growing. Some strains can take nutes over-feed and others cannot. Mines are forgiving. Since your in the Seedling to veg stage, your NPK needs to be 2-1-1. Your nitrogen needs to be higher than your potassium and your phosphorus.
I've studied on the ways marijuana has grown to know that "tomato" cages come in useful to my grow. They grow similar in tomatoes but in production, varies in growth.
There is still a chance for your plant to re-heal but you have to act quickly. If your budget can get tomato nutes. (Do what you can, that your budget allows) from experience; (the little that I have,) go organic. It's an envestment, but worth it.
I base my feeding (3 plants) per gallon. It's safer to feed your babies per gallon (as a beginner). With that you can calculate your ppm and pH accurately. Basic advice: pH ~6.5, I chose 6.0 ( based on my strain). Ppm: start from ~100 or 200 per week and go up, based on growth cycle and nutes.
Based on your post, your plant is dying. Not from over- feeding but from lack there of.
Invest in fertilizer. My pick is organic. Most don't believe in flushing towards the end of the flowering cycle, Others do. I'll leave that to your speculation.
Your plant needs vegetation nutes (2-1-1 NPK), organic or not is your preference.
