Yellowish leaves

Pro-bloom is a flowering supplement, it is not a fertilizer in its own right.........hence, your plants are starving! You need to get a bloom fertilizer, like "Pro Organic Bloom" from Terra Aquatica to use as well. The seaweed product and silica supplement you are also using are just that, supplements, and not fertilizers either.

Hi Dwonzal, My understanding of the Terra Aquatica TriPart is that you need to use all three parts - Gro, Bloom and Micro - throughout the grow. Gro contains higher nitrogen, Bloom has higher PK, and Micro contains the secondary elements like calcium, magnesium, iron, manganese, etc. It looks to me like you have a few deficiencies which is probably caused by the lack of Gro and Micro nutrients from the set. You're only using Bloom, and then two additives. I'm sure they're all great at what they do, but you're missing two key building blocks, hence the problems. If you can complete the set and feed the recommended dosage, I'm sure it will stop the spread and they'll recover. Good luck!

It just looks like it's not enough for these ladies. It's always good to go by recommended instructions for feeding plants at first but not every pheno is going to respond the same way. Point in case...your plants. I recommend increasing the feed because it's definitely an everything deficiency. N-p-k. Hope this helps

purtroppo non so che fertilizzanti stai usando quindi è difficile aiutarti per bene intanto trattasi di clorosi o ingiallimento delle foglie in pratica non riescono a produrre clorofilla le cause possono essere eccessiva irrigazione carenza di acqua ph sbagliato blocco nutrimenti o qualche carenza ci sono anche altri motivi ma non centrano nulla con il tuo caso il ph mi sembra sia giusto... devi valutare l'eccessiva o la scarsa irrigazione lo capisci controllando il terreno se quando vuoi irrigare è ancora bagnato non farlo lascialo asciugare per bene se invece è asciutto devi umentare l'acqua ma se dai 8 litri ogni 24 ore non è il tuo caso la cosa dei nutrimenti devi vederlo tu a meno che non mi dici che fertilizzanti stai usando e le quantita;)
