Nute burn or deficiencies?

SparkyGrowstarted grow question 5y ago

Can anyone give me a clue as to why the leaves on my fast eddy are going this colour, she’s fed every 2 days with tri part nutes. At 1/2 the recommended dosage. Guessing she’s got about 2 weeks until I start to flush her. Thanks

I would be tempted to alter your feed to grow 0ml/L Micro 0.7ml/L Bloom 1.4ml/L Cal Mag 0.5ml/L You prob have a few weeks left till you start flushing, your plant will be taking nutrition away from the big leaves at this stage. When they start looking bad like that I tend to remove them to allow light to lower parts. The reason I say change your feed to above is to lower N and increase P and K

@hashy thanks for that. I’m happy to adjust the ratio but just a follow up question. If like @inspireme says and it is potassium deficiency and I’m taking away 0.4 ml of grow and only adding 0.3 ml of bloom, going by the NPK numbers on the bottles isn’t that less potassium then they are having now? (Not at all sure how it works and if my thinking is at all correct so sorry if I’m being dumb)

Looks like it could be very early potassium deficiency to me.

Calcium deficiency, cal-mag now in hand, water now, or wait for normal scheduled water? Last water yesterday.Plants are suffering from an early stage of calcium deficiency, received a bottle of cal-mag today. Watered last night cause I didn't want to wait any longer. Should I wait for my next water (2 more days) or give a single dose of Cal-mag now, to get some calcium to the plant?
