update.i need help couse this shit started again,now it cant be the soil again this soil in which i transplanted aboy 10-12 days ago is the weakest soil i can find and they started growing just fine till today i saw the tips of leaves on 2 of my plants bending up and down and turning brown and the leaf seems to be a little pale yellow,2-3 days ago it was more a helthy green.i checked the runoff water and the ph is ok 6.8,i saw i thread where some guy has a potassium problem looks similar can it be that its a deficiency now
