Medium/grow method: Soil
Feed: and supplements used: Gh flora series half dose of what is written
water source: Ph'ed tap water
Strain/age: 1 month in flowering
light used: 300watt cob
Climate:25-29 degrees of celcius under %50 humidity
Additional info:
Hello everybody, this is my first grow and before i planted my seeds, i read lots of stuff about growing cannabis and i was thinking i was going to grow some beautiful plants with all those information i have learned. But in practice everything has gone wrong with 2 of my girls out of 3.
I am watering them once in 3 days with half a litre of water and i feed them every other watering with GH flora series(half dose of what is recomended. Always used ph'ed(6.6) water. They have another sister which is healthy and showing no signs of def.
One of the girls had yellow leaves starting of the bottom and went upwards. At first i thought it is normal since it's in the flowering stage and getting the N from the leaves. I was not into giving more nutes due to the possibilty to burn the plant. But eventually she lost most of its leaves and still has yellowing leaves issue. With last feeding(yesterday) i added half strength cal-mag(4-0-0) for the first time and raised the N a little bit(I normally add 0.5ml/L, i raised it to 0.70). But today they have purple spots on some of the leaves(Which i think is phosphorus def) and twisted leaves near to the top. I'm really worrying if they are dying. Should i flush them or increase the amount of nutes ? Thanks in advance guys..
