Hi Folks.
Ok, heres my set up,
Sweet Seeds (I think) Red Devil
No of plants 4
Grow Type Soil
Grow Stage Veg, 19 days from seed pop
Pot Size 15 Litre
Lights 275 Watt LED
Nutes Advanced, Sensi Grow
Medium 60% Coco 40% Clay Balls
Ppm 600
PH 5.8
RH 55%
Room Temp 29o C
Solution Temp 25oC
Room Size 10'x15'
Pests None
Ok, just to reiterate, this is an autoflower and my 1st attempt with autos, I know the room conditions are ok as I have some very healthy Dina-fem KushnCheese growing along side these autos.
I started them in rockwool blocks, giving an 8th of reccomended nutes, 1st few days the growth was very good but then the lower fan leaves started developing what can only be described as grey scale, almost like rust on steel, I wondered if perhaps it was nute burn so flushed with water for 3 days but with no improvement, growth was still fairly good but the leaves that got the 'rust' 1st are now yellowing and drying out, there is some purple on 2 of the plants stems, being a red version of Big Devil, this could be normal.
I guessed as flushing made no difference perhaps it was a Nitrogen deficiency so I upped the nutes to a quarter then half the reccomended nute dose but the problem still persists.
When the 1st roots showed through the rockwool I put them in the coco mix and this seems to have shocked them into much slower growth, the growing tips are a good healthy colour but as they age they develop the grey rust then yellow and start drying and curling under.
I have since read a few posts where people say do not feed autos until week 6 so could the light feeding I gave them in their 1st days be the cause ? Ive never seen anything like this, I have looked through all the threads on plant problems, pictorials etc & the closest thing I can find is Nitrogen deficiency but I cant believe that as I am using a balanced feed, a feed I have used succesfully for a few years so I am stumped. What on Earth is the problem ?
I apologise for not posting and photos, I am new to this forum malarky so havent yet figured out how to yet.
I would very appreciate any help on this, I like the idea of autos now they have improved but I am obviously doing something detrimental to autos whereas my method works fine on normal strains.
Thanks Folks.
