Hi all, first post here! Been a home grower for three years, mainly Coco. My latest grow is a Strawberry Cheesecake Auto.
Got into second week of flower and looked like too hot on the nutes (dark green leaves, slightly glossy, with slightly burnt tips) so I cut back from 1.5EC to 1.3EC (water 0.4EC). Now in the fourth week of flower and I'm getting new growth looking pale and with brown patches appearing. Lowest 2 leaves have turned yellow but this has been ongoing for last 5 weeks.
I'm wondering if there is nute lock due to too much nutes still, or if I now need to raise the nutes. Could it need cal/mag?
I'm a little stumped, this is the first time I've had an issue like this in Coco (I had plenty of other problems though).
Yer i think some calcium will do well here mate, but just a little, go for like 0.5ml per litre for a couple of feed and that should be fine i think 
You not using any pl 13/14 though? The plants would do well with some of that at this stage
Thanks Macky, I'll give it a little calmag and see how it fares. Normally start the PK 13/14 on week 6 of flower, think it would like some now? Just concerned about overdoing the feed. As an aside, wtf is with Canna Coco feed schedule calculator? I choose light feed and it's still way too much, I never give more than half what is suggested!
I never give more than half what is suggested!
Me neither brother, you are going to be a natural at this lol.
