If so, What and When? Are plant's infected with pest's Yes, Springtails & Thrips (Thrips have been knocked back to v.small population) This started a few weeks back, First I thought it was a MG def so I added Epsom salts and it just got worse.. Then saw some pictures of leaves simielr to mine with P & K def's.. Sorry for the awful picture, Those 3 colas are 1 plant that is most affected but the others are slowly catching up with it. Should I flush or are they just hungry? , PH problems? (dont see how)
Hey Man, how goes it? Looks like you have been a pretty busy guy. Good looking work there my man. Well, imho, if you are 7 weeks into 12/12 then what I am seeing is not strange. As the plant gets closer to maturation the big sun leaves will yellow and die off. That is what I think that I'm looking at here. Do you have any idea of how long it takes this strain to finish? I harvest when the 3 push of Trich's starts. Right around 10-14 days before chop, chop is when you would stop feeding and just flush. 7 days before I chop, is when I cut off whatever big fan leaves are remaining. Hope this help, and chill a bit...the finish line is in site...pretty soon, you'll be puffing your herb.
Cheers for the reply mate, The early signs of this started at week 5-6, I thought it might prolong flowering as it cannot uptake its nutrients? I also have a 12 week strain in my tent which has similer problems but not as severe yet, Think I should just carry on and flush at week 8? and week 11 for sativa?
Hey man, without knowing the estimated flowering period and not being able to see the trichs it will have to be up to you. The buds didnt look all that plump but then again I cant tell from the pic. Id say for the plant pictured go ahead and start flushing. (i.e, indica, already at 7 weeks, give it one or two weeks flushing that will put you at 8-9 weeks flowering.) If it really is having nutrient lockup then that would probably be the best idea. Just my opinion from what I could see and understand. Peace
Yeah, I'd go with the flush at week 8. when the very first drops start coming out the bottom of the pot, catch enough of those to check the ph and the ppm. The one in your tent is, imho, just a few weeks behind. What nutes do you think are locked out? BTW, throw down some more Porn. No free rides.
