I love your setup....clearly well thought out.
Could be, but if you don't see any leaf yellowing then I wouldn't worry too much about a N deficiency. I'd also be very careful not to go overboard with N at this point. It would be a shame to burn them and set them back at all at this stage, they look so nice right now.Reddish stems can be the first sign of an N def but usually just indicate a leaf is mature and that the plant will eat it if needed.
As I said it is generally an indication that it is a mature leaf and IF there is an issue they are the first ones the plant loses.I frequently get red stems when the plant needs absolutely nothing at all. Some of it is simply genetic or environmental, but definitely good advice to keep an eye on any deficiency that might be related.
Agreed! Except that cannabis doesn't need much P. Its the primary nutrient consumed during flowering cycle. I presume you meant during vegetative stages.As I said it is generally an indication that it is a mature leaf and IF there is an issue they are the first ones the plant loses.
IME P def comes from other stresses. Cannabis really doesn't need much P so if it's not getting enough it's probably a lockout issue.
I will agree that if there is a P deficiency its probably from PH drifting.No I mean during it's entire lifespan. Flowering cannabis needs less N and more P than it does during veg relatively but it still needs more N than P. I'm basing this on what I've seen of tissue sample data for cannabis and flowering the same cuts with low N high P and high N low P and seeing healthier more potent plants with the low P diet. I would love to have a hydro setup and take res samples to analyze mineral uptake and use that information to design a complete food that was actually what the plants ate. Cannabis has very similar nutrient requirements to fruiting plants like tomatoes and peppers which do best with feeds that are around 3-1-4. The big difference is that cannabis will flower with a slight excess of N over K while most peppers and tomatoes prefer an excess of K for optimal fruiting response. Bloom products have a place as boosters but not base nutes IMO.
Nice, are you running Jacks? I love it for the money. What do you think about the the 15-10-30 for mid to late flower? I wish it was available in the buckets like the other Classic blends. It seems it would have enough N for a long haul and a nice K kick for bulk and resin.I've been running 20/20/20 straight through and doing great. I have a lot of friends running either the Citrus FeED or the Peat Lite which are 20/10/20s and other friends who run DG's foliage pro as a base straight through and that's 3-1-2. I tend to like long flowering sats and they do so much better high N low P. Losing all your mature fans at week 5 is ok when you have an 8 week strain but a 14 weeker will have problems...
