You can also feed plain water once if this happens, before resuming on a slightly lower strength feed.
The plant will generally be a darker green when this happens and the foliage can have a slightly waxy look to it.Īgain it's nothing major and just means you should lower the EC of the feed by 0.2. This is the first sign your plant is a tad bit overfed.
This is when the very tip of the fan leaf curls down or the very tip becomes yellow/brown. The second thing to look out for is hooked leaf tips or tip burn. you're back in the optimum feeding range again. What you will see is a continuation of healthy growth and the lower leaves will stop paling. Go easy with adjustments and whatever you do don't expect the leaves to return to their bright green because that won't happen. It just means your plant is a bit hungry and will indicate that you need to up the EC by 0.2. This is the first sign of nitrogen deficiency. Sometimes it can be a general plant thing, but if your feed is close to spot on, it'll only show on lower foliage. The first thing to watch for is the very lowest main fan leaves for paling. The Key to this stage of growth, as it is through all of the veg period, is to keep an eye on two things: By this point they're on roughly 1.2 - 1.4 EC of formulex, which should give you a very good general idea of how they feed through this early stage of their life, and how quickly and healthily they come on on just formulex and nothing else.
