I have checked the plant problems thread but im still unsure what this can be. was hoping someone can look at the pics and help me pinpoint better.
So a little info:
This is week 6 of flowering.
Growing in FFOF soil.
Water gets ph'd around 6.5 before feeding/watering.
temps are 75F-80F.
under a 400w HPS
Feed every other watering with 1tsp molassas, 2 tsp iguana bloom. 1/2 tsp cha-ching, usually feed 1-2 x a week.
Other plants looks the same, some worse than others.
I thought maybe it was nutrient burn, which it may still be. I gave a good flush of several gallons of ph'd water the other day and couple days later dont really see much difference. I always hear the plant "bounces back" after a flush but didnt really see anything out of the ordinary.
The problem is the yellowing and browning start somewhat together but the browning starts at tips and edges then works its way into entire leaf over time like in pic 3. Its at lower and top leafs.
I did a soil test, which tests NPK and Ph of soil. the NPK of the soil looked good except for N, the reading showed next to nothing for N and the ph was good. P and K looked good.
So Im thinking it may be a combination of N defficiancy and nute burn or lacking a micronutrient. Just wanted to get other opinions on this and maybe someone will see the pics and say "oh that is a classic sign of ____"
Thanks for the help!
