First time Green Gelato with my-lar tent

uups...!! I start the PH-case what I wrote and edit last diary week. I had little earthquaqe in greenhouse. Tap water PH was secretly rise up to PH 8, I dont know when. I watched how the left side of the flowers (leafs) slowly turn yellowed past 10 days. I began to have doubts about nutrient deficiency - copper and zink matched the description. First advice is check the PH. I check and fertilizer solution on tray was PH 7.1 - I dont know how long time. Anyway I fix it to PH 6 last friday and I flush pots PH-fix solution - but i dont see much progress. Warnings what I read Zink - If the plant is budding, its flowers may stop growing or even start dying if the problem isn’t corrected. Copper - In flowering it’s important to correct a cannabis copper deficiency as soon as possible because buds may stop maturing if the plant isn’t fixed up right away. And fact is that to my eye it seems that Buds are little change colour but grow has been slow. I will continue follow right PH and I dont add extra Cal+MG anymore and little less nutes from now if girls could recover Now Feelings are not so high - but yes it still turns into joy and high 😅
