First Grow: Linfa Weezy with Royal Dwarf

The correct answer is, what’s the ppm’s levels ?
You can’t grow in coco following blindly manufacturers nutrients schedule, you absolutely need an EC/TDS meter to check the Electrical Conductivity and the Total Dissolved Solid of your solution.

But in my personal opinion, by reading the leaves, the EC of the media is way too high, creating nutrients burns and random deficiencies due to nutrients lockouts.

check the runoff EC if growing with mineral fertilizers. Check the pH. Usually if you follow the recipe of the manufacturer you're set. I suggest not to cut the leaves if they are mainly green yet, the flowering might slow down

Do you know your soil's pH value? Looks like Macro nutrient deficiencies. If you've never flushed your soil before, now would be a good time to do it. That will reset your soil with the pH you want, and to flush out built up nutrient salts that could be causing your plant to burn and be deficient due to lock out.

Depending on the size of your pot, for example, if you had a 1 gallon pot, you would flush pH adjusted tap water through your root zone with 2 gallons. Then allow the soil to dry out so the pot feels light again, then feed with a balanced, pH adjusted nutrient mix.
