What deficiency is this?

[Revolutionary9]

Any guesses on what this deficiency is?


I don't think it's a PH problem because the water im using (from a ditch) is right on. The ferts i use tend to push PH up a little bit but the soil should buffer that, and i have 4 other plants doing great (nice shade of green, no yellowing)
I think this strain is just extra sensitive to nutes

The strain is CAPSTONE from Purple City Genetics = Super Lemon Dawg x (Cherry Pie x Orange Apricot) (sativa dom)I've been feeding once a week with worm castings top dressed, and a liquid bloom fertilizer derived from rock dust called BioLink 0-5-5
I also use a bit of cal mag plus and molasses
I water them every 3 days or so, whenever soil is dry.
The soil is really light, quality stuff from a big soil place nearby.

Not enough N and too much watering looks like to me. Since your seemingly organic might want to do quite a few guano teas.

Yeah, I agree N Deficiency. Its a Myth to not supply N to plants during flowering.
N to a plant is like Protein to a human.

How would you grow with no protein??

Flowering is the time the plant uses the most food, water, and light. Its not logical to limit N/Protein.

If humans do not consume enough Protein, we go catabolic, or we start eating ourselves. We go Catabolic/cannibalize ourselves.
Protein in Latin means of First Importance. Its essential for Growth, and Repair, not to mention Immune Function.

Id get some Peruvian Seabird Guano. 13-11-2...0-12-0 and Kelp. Might also find 0-11-0 or 0-13-0 No liquid kelp either. Dry. AZOMITE. Id mix 1.25tsp 0-12-0 to 3/4 tsp 13-11-2 per gallon water, in mesh bag Never loose. Can also add 1 tsp per gallon of soil. Level tsp too. Not heaping. 3/4tsp 0-12-0 x 1/4 tsp 13-11-2.

Reverse the ratio for Veg.

Thank you guys. I definitely bought into the idea that they don't need nitrogen in flower. Worm castings just isn't enough i guess. Thought the soil had plenty of N but i guess these are hungry plants
The simplest deficiency had me stuck / frustrated so thanks again

As he already written to you ambertrichome [...]Flowering is the time the plant uses the most food[...] and as you can see from the graph , in the beginning flowering phase you are at most nitrogen request of the plants.

Now that is a valuable pic +1

Its just simply not logical to cut back on Protein/Nitrogen, when youre trying to add mass.
