Phosphorus deff? or cal mag?

Ph is 6.2
temps:22-26 celcius

im giving nutes once a week with 1ml/l Biobizz Bloom(plant takes 2L of water every 3 days ) do you think its a posphorus def?

thank you

To low ph if soilless, definitely up your bloom looks like your in 3-5weeks of flower depending on strain so your bloom definitely needs to be higher,it's organic so depends on medium but you can follow the bottle chart, I use it. Definitely not lock out if it's all you've given. Get your ph to 6.5 slow. If in week 5I'd without doubt be giving it 2ml. A litre at least probably more, depends on what medium your in. I'd be feeding more often too, try f w f w.

thanks for the answer ...Soil is Biobizz all mix. I watered the plant with ph water 2 days ago so the soil was still moist so I gave her 1 litre instead of 2 she usualy at 7.0 ph, with 2ml of Bio bizz bloom ,0.5 ml Cal+mag +1 ml Alg a Mic.
Is that okay ? And shall i wait now for her to dry and then continue as normally with just 2ml/L on every feeding?

All mix is a heavy nuted one, I always had issues using it with no micro additive like heaven for example but you should get to the end. I'd only give cal mag for a couple of waterings, you don't need a lot in bio bizz, if at all, depends on strain. Try to get your ph stable, jumping about from 6.2 -7 isn't good, some strains will hate that. Try let them dry right out between watering, when pot is light, or leaves droop a bit. Otherwise less oxygen less growth. It's all a balancing act. You should be using grow also, bio bizz, but in all mix your probably ok. Definitely start thinking about using a booster like big bud , it does work.
