Hi!
Dear friends, I need help!😱
I see yellowing progress of leaves . At first I thought it’s normal, but it’s far to the harvest – 3 weeks. I compared the different images and detected a lack of phosphorus... Yesterday I changed the solution completely, now use only Flora Nova Bloom. Maybe someone else will tell me?
The 104th day:
Satta made me jittery. Leaves have strongly yellowed and dried after jumps of pH, the plant has lost about 30% of the leaves during 3 days. As I’ve written before, the solution was changed, I've washed the tank and filled Flora Nova Grow. ... Improvement has not come. pH grows on 0.3 units during 12 hours, ppm decreased from 1100 to 1020 - that is mean the plant actively eats anions, phosphorus, sulfur and nitrogen.
I regulate the pH in the morning and in the evening, and half an hour ago according the advice of a reputable friend. I added 15 ml of ripen to the solution. Spray Biobud 1 time a day, I think I’ll stop to spray in a couple of weeks before Harvest, because I do not want to smoke chemistry. Next we will look at the dynamics. I shifted the lamp up by 5 cm. The central cola was already near cooltube (15cm). When I changed the solution one little cone was broken, now it is drying on the box 😁. When you look at the plant every day it seems there is no dynamics, but looking at the pictures in the diary – there is 😊
You can manicure yellowed leaves, that obstruct the light. And reduce the EU to 1 in two weeks before the harvest. So it will be with gain of weight. Everything is ok. slight yellowing is not terrible 😊
This method is good for soil, because there is remains of nitrogen in the soils as a rule. And you will have nitrogen from the leaves and and stems, all will turn yellow all at once. Give nitrogen for 3 days. It’ll absent in the solution only some last days. do not rush, read more about DWC 😊
Algae were due to solution temperature. Know Cannabis grows cool at a temperature of 18-20 degrees. If the temperature is lower, it will die, if the temperature is higher, it will stop growing. 26 is ass, drain the water.
When you make photo under HPS set “filament lamp” in the camera and hold a blank sheet of A4 under the lamp (light will be scattered). The lamp gives much light and makes the light spot. It’s better to do photo without HPS, the best option is under fluorescent light with the flash. Experiment 😉
Don’t play with pH. It may be fatal at this growth phase. If plants eat a lot – give them more😏
Today ph is 5.3, ppm is 860. I added 1l of water (pH 7) and 10ml of Flora Nova Bloom. At the result pH is 5.22 and ppm is 1240. Flora Nova is very acidic at the first hour after mixing solution, pH decreases on 1-1.5 , but some times after it stabilizes. Satta looks normal after ph fluctuations.😋

Stop to spray at the second half of flowering, because the mold can be =)
What is the solution now? If acidic – it want more potassium. It's time to reduce the concentration. The cones will not gain in volume, maturation stage started.
It’s nice, good luck!
Scrog was set very high for this flowering stage. In this time there is no fast growing and colas have already been braided into the net (you missed this moment). Now your scrog is for beauty, it doesn’t perform its intended use. your next steps should be such: set scrog a below, so the cones will be above it, do it slowly and carefully; or remove scrog and pull branches to the side using ropes, it’ll be easy.
If we eliminate the nitrogen, it will spoils the food. nitrogen is the conductor of phosphorus and all the other elements. phosphorus without nitrogen is not absorbed, it remains like dead weight in the the substrate and becomes superfluous. We need to decrease nitrogen and to add potassium, and the most importantly it is to reduce the total EU on output to 1 EU. After the bush bloom according passport and gains weight. As a rule before the end of the last week plant doesn't eat all fertilizers. EU is about 0.5 - 0.7. It tells us that the nitrogen is ended, all the rest will not be absorbed. Who breaks the nitrogen early and lose weight of cones 😊.
Maybe you need to slow nitrogen? Potassium monophosphate only hasten the end, and you'll loose opportunity to grow weight of cones. Give solution with increased phosphorus. I would have done:
1. Ash
2.NPK 90-110-200
By personal experience: At the start of the flowering I always put the ash. Thereby nitrogen is sharply reduced. The plant is quickly switched to the flowering. Then nitrogen is reduced to normal value. High nitrogen at the vegetation stage gives long flowering.
Hi! From the 4th week you must add to Flora Nova Bloom some phosphorus and potassium, such as PC. Bloombastic by Atami is good. You can't correct yellowed leaves, but have to add elements for growing cones
Thanks for advice, bro. I can’t move the scrog, it’ll break two beautiful colas (they bent under the scrog on 10-15cm). And fixing prevents gently stretching. I think it'll stands another week, and then I’ll take off it.
About stretching…I’ve already pulled as far as possible, the extreme sides haven’t enough light. If I stretch it more they will be absolutely in the shade. I’ll do folding of leaves, just do not quite understand - take the wire and carefully tie them to the trunk?
